Scan the SPI Flash Memory IDCode This demo uses the SPI Flash Memory Controller and UART modules of the Mini SoC to scan the memory device identification code of the on-board SPI Flash Memory and display it on the terminal output. The transaction is logged to the on-board SRAM through the SRAM controller module. 8 MachXO Mini Development Kit User’s Guide To scan the SPI Flash Memory IDCode: 1. From the terminal Main Menu, press 1. The ID number is returned as a hex value and the transaction is logged to the on-board SRAM and the current address pointer is indicated. Example: ID:0x12 (SRAM ADDR:0x00010) Note: The ID for your board may differ. Reading the I2C Temperature Sensor This demo uses the I2C Controller and UART modules of the Mini SoC to read the on-board I2C temperature sensor, convert the raw data to Celsius units and display it on the terminal output. The transaction is logged to the onboard SRAM through the SRAM controller module. To monitor temperature: 1. From the terminal window press 4. The Mini SoC normalizes the meter output for the ambient temperature and lights 4 (D0-D3) of the LED bank (D0-D7). 2. Place your finger on the on-board I2C Temperature Sensor (U14) for 2 to 5 seconds. Depending on your skin temperature, the level should influence the temperature monitor (1 LED = 0.25°C). 3. From the terminal window, press 2. The current temperature in degrees Celsius appears and the transaction is logged to the on-board SRAM and the current address pointer is indicated. Example: Temp:30.50°C (SRAM ADDR:0x0000B) Reading the DIP Switch Bank This demo uses the UART module of the Mini SoC to read the user-input switch inputs 1-3 of the DIP Switch Bank (SW1) and output it to the terminal as a hex value. The transaction is logged to the on-board SRAM through the SRAM controller module. Note: SW1D (Schematic Sheet 3 of 8) of SW1: SW_SPST_4 is reserved to enable/disable the on-board Sleep Mode circuit. To read the DIP Switch: 1. From the terminal window press 3. The switch setting is returned as a hex value and the transaction is logged to the on-board SRAM. Example: SW:0x0 (SRAM ADDR:0x0000A) Reading the Transaction Data History from On-Board SRAM This demo uses the SRAM controller module of the Mini SoC to read the transaction history logged to on-board SRAM during the period the Mini board has been powered. 9 MachXO Mini Development Kit User’s Guide To read data history from SRAM: 1. From the terminal window press 5. The transaction log is listed. Example: SRAM: Temp:30.50°C ID:0x12 SW:0X0 Copy Data History from On-Board SRAM to SPI Flash Memory This demo uses both the SRAM and SPI Flash Memory controller modules of the Mini SoC to copy the transaction history logged to the volatile on-board SRAM to the non-volatile on-board SPI Flash Memory. To copy data history from SRAM to SPI Flash memory: 1. From the terminal window press 6. The data log is transferred and the terminal indicates “Done”. Example: Done. SPI Flash: Temp:30.50°C ID:0x12 SW:0X0 Read SPI Flash Memory This demo uses the SPI Flash Memory controller module of the Mini SoC to read the on-board SPI Flash Memory. To illustrate the non-volatile nature of the Flash memory, you may power-off the Mini board at any time by disconnecting both USB cables. Reattach the cables, restart the terminal application, and then perform the memory read to confirm the data is intact. To read data history from SRAM: 1. From the terminal window press 7. The transaction log is listed. Example: SPI Flash: Temp:30.50°C ID:0x12 SW:0X0 Note: To clear the Flash memory, press SW1 to reset the Mini board and clear the on-board SRAM. Copy data history (currently cleared) from the SRAM to the Flash memory. Re-Display the Main Menu During the demo session the main menu will scroll off-screen. To redisplay the menu, press 0. You may confirm that the SPI Flash memory will retain data in a power-off condition by removing both USB cables to power-down the Mini board. Rerun the memory read to confirm the data is intact. While the Mini board is powered, a running log of all transactions is logged to the on-board SRAM. 10 MachXO Mini Development Kit User’s Guide MachXO Sleep Mode Demo The MachXO sleep mode demo illustrates one possible implementation for power savings. Using this method, the MachXO device provides supervisory logic to control its own SLEEPN pin. Periodically, the device becomes active to monitor a trigger event. If the event is not present, it deactivates to save power. When the SLEEPN pin is asserted (low), the following occur: • The device powers down internally, dropping power consumption to less than 100µA • All I/Os are tristated When the SLEEPN pin is de-asserted (high), power is restored and the MachXO is reconfigured and ready to operate in 1ms or less. Due to the dramatic reduction in power consumption and the fast “instant-on” capability, a scheme can be implemented with a few simple, inexpensive external components deactivate the device and reactivate with a duty cycle ratio that saves substantial power. Figure 3. Sleep Circuit (Abbreviated) MachXO R56 10K C60 0.33uF S1 I/O (14) I/O (89) Q5 R59 10K C59 33uF R20 10K SW1D SLEEPN (70) When I/O pin 89 goes low, C60 discharges. PNP transistor Q5 then conducts, discharging C59. Provided SW1D is closed, this value is forced onto the SLEEPN pin of the MachXO device, putting it into low power sleep mode. Once in sleep mode, all I/O pins are tristated, allowing C60 to slowly charge. This then turns off Q5 and allows C59 to charge. Once the amount of charge is sufficient to place a logic high level on SLEEPN, the device returns to normal operating mode. The MachXO begins operating, as defined by its programmed function. In this demonstration, I/O pin 89 is driven high initially to allow the device an opportunity to remain active long enough to check whether switch S1 is pressed. If S1 is not pressed, I/O pin 89 is driven low and the cycle repeats. If S1 is pressed at that moment, the device remains operational for the entire cycle of an internal counter (~3 sec) and the LEDs are illuminated during this time. S1 is then checked after each subsequent cycle. To exit sleep mode or to reprogram the device, open switch SW1D (SW1-4). Download and Program the MachXO Sleep Mode Demo Design To download the MachXO Sleep Mode Demo source files and reprogram the Mini board: 1. See the Download Demo Designs and Programming Demo Designs with ispVM sections of this document. 2. Use .\Demo_MachXO_Mini_Sleep\project\impl1\mini_auto_sleep_impl1.jed to restore the MachXO Sleep Mode demo design. 11 MachXO Mini Development Kit User’s Guide Operating the Sleep Mode Demo To operate the Sleep Mode Demo: 1. To observe the sleep/wake power savings, place voltmeter leads across J2 (VCC CORE) or J3 (VCC AUX). Each number attaches across a 0.2 ohm resistor between the +3.3V supply rail and VCC_CORE or VCC_AUX. The average voltage level will drop significantly during the sleep/wake cycle. You may estimate current consumption with Ohm’s Law where I = V / 0.2 ohms. 2. Toggle SW1_1 (A), SW1_2 (B), and SW1_3 (C) to the OFF position. All user LEDs D7-D2 are dim and user LED D1-D0 are lit. The DIP switch inputs 1-3 are tied directly to the LED bank according to the table below. SW1 LED N/A 0, 1 (ON) _1 (A) 2, 5 _2 (B) 3, 6 _3 (C) 4, 7 3. Adjust DIP switches 1-3 and note the pattern on the LED array. 4. Enable the MachXO Sleep Mode circuit, toggle the SW1D (4) to the ON position. The MachXO enters a sleep/wake cycle. According to the parameters of the external Sleep Mode circuit the MachXO will periodically wake to check for user input and drive the LED bank. If no inputs have changed it will return to the sleep state. The LED bank will flicker during the sleep/wake cycle. 5. Depress SW1. The MachXO wakes for ~3s and the LED array is lit according the SW1 values. Once the SW1 is released the Mini board reverts to the sleep/wake cycle. To exit sleep mode or to reprogram the device, open switch SW1D (4). Note: Pressing push-button SW2 will assert the dedicated MachXO SLEEPN input with any design. TransFR Demo This demo illustrates the TransFR (TransparentFieldReconfiguration) feature of the MachXO PLD. The TransFR solution uniquely allows logic to be updated in the field without interrupting system operation. The demo first programs the MachXO device with a count-up function, which drives eight LEDs. It then freezes these outputs while a count-down function is loaded into the device’s SRAM configuration space. The demo then concludes by releasing the outputs to display the count-down function. The TransFR feature allows the MachXO to lock its I/Os in a deterministic state while a new configuration is loaded into the device’s SRAM configuration space. This minimizes system interruption by dynamically configuring the MachXO with a new pattern without tri-stating its output pins. The inputs for the incrementing and decrementing design are: • CLK: Clock to drive the counter and internal logic • RSTn: Resets counter to 0, asserted low. • CNTEN: Enables counting when asserted high. • CAP_EN: Captures the counter value on LEDs when asserted high. • LOADn: When asserted high, enables the counter values to be displayed on LEDs. When asserted low, this input tristates the pins that drive the LEDS, and forces a synchronous load of the values captured by the CAP_EN. 12 MachXO Mini Development Kit User’s Guide The CLK connects directly to the oscillator on the board. The RSTn (global reset) is connected to user push-button (S1) of the Mini board. The other three inputs come from the SW1 DIP switch bank at the right hand side of the Mini board. The outputs of the MachXO device are as follows: • LED_OUT[7:0]: Most significant eight bits of the counter to be displayed through eight LEDs to show the counter values in binary format. Download the TransFR Demo Design To download the TransFR Demo source files, see the Download Demo Designs section of this document. Programming the Initial Up-Counter Design To program the up-counter design JEDEC file: 1. Set the control signals with the Mini board SW1 DIP switches as follows: • LOADn (SW1_1) is set to 1 (OFF) • CNTEN (SW1_2) is set to 0 (ON) • Cap_en (SW1_3) is set to 0 (ON) 2. Use ispVM to download the Mini board with the .\Demo_MachXO_Mini_TransFR_Up_Counter\project\up_count.jed file. See the Programming Demo Designs with ispVM section of this document for details on programming the Mini board with ispVM. The up-counter design is first loaded into Flash then immediately into SRAM space. In doing so, the LEDs will light up, showing the initial value of the counter (all 1s). The SRAM and Flash configuration spaces are now both programmed with the count-up function. 3. Toggle SW1_2 CNTEN to the OFF (1) position. The LEDs show the up-counter values. In the following procedure you will load a down-count function into the MachXO Flash program space. After the TransFR operation is complete, the down-counter results will be displayed on LEDs. 4. Toggle SW1_2 CNTEN to the ON (0) position. Note the up-counter value. Download the Down-Counter Design to the MachXO Flash Space To program the down-counter design JEDEC file: 1. From ispVM System, choose ispTools > Scan Chain. The New Scan Configuration Setup window appears. 2. Double-click the LCMXO2280C entry in the Device List. The Device Information dialog appears. 3. From the Data File section click the Browse button. The Open Data File dialog appears. 4. Browse to the .\Demo_MachXO_Mini_TransFR_Down_Counter\project folder, select down_count.jed, and click the Open button. 5. From the Device Access Option section, choose Flash Background Mode. 13 MachXO Mini Development Kit User’s Guide 6. From the Operation section, choose: XFLASH Erase, Program, Verify, and click OK. 7. Choose Project > Download. ispVM reprograms the Mini board. Programming requires about 20 to 40 seconds. A small timer window will appear to show elapsed programming time. At the end of programming, the configuration setup window should show a “PASS” in the “Status” column. The down-counter program is now loaded into the Flash configuration space. Since the up-counter function is still programmed into the SRAM configuration space, the count up function still appears on the LED bank. The count-down function will be loaded in the SRAM space when the TransFR operation is performed in the next procedure. Transfer the MachXO Flash to SRAM Space At this point in the demo, the down-counter function is loaded into the Flash configuration space, and the up-counter function is loaded into the SRAM space. In this section, an *.svf file is generated and used in the ispVM SVF debugger tool. The debugger tool steps through the SVF file to lock the I/Os at their current state (via TransFR technology), load the Flash configuration space into the SRAM space, then release the I/Os. This allows the loading of a new configuration without the I/Os ever having been tri-stated. To prepare the transfer of Flash configuration contents to the SRAM space of the MachXO: 1. From ispVM System, choose ispTools > Scan Chain. The New Scan Configuration Setup window appears. 2. Double-click the LCMXO2280C entry in the Device List. The Device Information dialog appears. 3. From the Device Access Options section select Flash Background Mode. 4. From the Operation section select XFLASH TransFR. 5. Click on the Expand button. 14 MachXO Mini Development Kit User’s Guide 6. From the I/O State section, select Leave Alone. Click OK. 7. Choose File > Save As... The Save As .XCF File dialog appears. 8. Browse to the .\Demo_MachXO_Mini_TransFR_Down_Counter\project directory, specify TransFR.xcf and choose Save. 9. Choose Project > Generate SVF File... The Generate SVF File dialog appears. 10. From Source File (*.xcf) section, choose the Browse button. The Browse Source *.XCF file dialog appears. 11. Browse to the .\Demo_MachXO_Mini_TransFR_Down_Counter\project directory, choose the TransFR.xcf file and click Open. 12. From the Save SVF File as: section, choose the Browse button. The Browse SVF File dialog appears. 13. Specify TRANSFR.svf file and choose the Save button. 14. Click the Generate button. ispVM reports: Build Single SVF File: Successful. 15. Click OK and click the Close button. You have now built the TransFR serial vector format (SVF) file that you will use in the ispVM SVF Debugger program. To transfer the Flash configuration contents to the SRAM space of the MachXO: 1. Choose ispTools > SVF Debugger... The SVF Debugger application initial Svf File1 screen appears. 2. Choose File > Open. The Open Data File dialog appears. 3. Browse to the to the .\Demo_MachXO_Mini_TransFR_Down_Counter\project directory, choose the TransFR.svf file, and click Open. The TransFR.svf code appears in the SVF Debugger window. 4. Choose Configuration > Cable and IO Port Setup... The Cable and IO Port Setup dialog appears. 5. Click the Auto-Detect button. The SVFDebugger detects the EzUSB port and USB cable. 15 MachXO Mini Development Kit User’s Guide 6. Click OK. 7. Place the cursor at the top of the file, above the first instruction. This will ensure that you step through all the instructions in order. 8. Press the Step key F11 (Command > Step). The SVF Debugger advances to the next line of executable code. 9. Step 2-3 more times. Each time you click the STEP button, it executes an instruction, then advances to the next instruction. Each time you step through an instruction, it is translated, goes through the USB download cable, and is executed in the MachXO device. 10. Continue to slowly step through the code and stop just before getting to the instruction that reads (about Line 51): ! Shift in ISC ERASE(0x03) instruction SIR 8 TDI (03); Note that LEDs are still counting up. Now step once while watching the displays. Note that the displays have stopped. The device outputs are now under boundary scan control. A TransFR operation (embedded in the just executed instruction) has locked the outputs at whatever count values they were at when the TransFR action occurred. 11. From the Mini board, toggle the SW1_2 CNTEN to the ON (0) position. This will stop the counter from counting once the device is out of the boundary scan mode. 12. Press F11 until the cursor highlights the BYPASS instruction: ! Shift in BYPASS(0xFF) instruction SIR 8 TDI (FF); 13. Press F11 once more. The cursor highlights: RUNTEST IDLE...; At this point, the new pattern has been loaded into the SRAM memory space and the switch inputs are monitored, but the outputs are still controlled by boundary scan and are still frozen at the same values. 14. Press F11. SVFDebugger reports “Process Done. No Error”. Click OK. The MachXO I/Os are now released from boundary scan control and counter’s initial value (0xFF) is driven to the LED displays. The displays do not start counting yet because the CNTEN is deasserted. 15. From the Mini board, toggle the SW1_2 CNTEN to the OFF (1) position. The LED display starts counting down from the initial value. The MachXO has exchanged the up-counter for the down-counter function, without disrupting the output PIOs. Another variation of the demo is to initialize the down-counter with the current state of the up-counter. After step 12 in the procedure, toggle CAP_EN (SW1_3) up and down once (toggle from ‘ON’ (0) to ‘OFF’ (1) and back to ‘ON’ (0)), then toggle LOADn (SW1_1) down and up once (go from ‘OFF’ (1) to ‘ON’ (0) and back to ‘OFF’ (1)). Following step 14, the counter value displayed on the LEDs will not change. Following Step 15, the down-counter will begin from the value displayed on the LED bank. Note: See TN1087, Minimizing System Interruption During Configuration Using TransFR Technology for more information. 16 MachXO Mini Development Kit User’s Guide Download Demo Designs Lattice distributes source and programming files for a variety of demonstration designs compatible with the Mini board.
