The EVM contains one HDC2022 (see Table 1). Table 1. Device and Package Configurations DEVICE IC PACKAGE U1 HDC2022DEB WSON (6-pin) DEB The EVM hosts an MSP430F5528 microcontroller (µC) as well as the HDC2022. The µC is used to control the HDC2022 and communicate with a host PC through a USB port. The EVM is designed to be broken into two sections if desired. The sensor section can be separated from the µC section of the board to reduce thermal mass surrounding the HDC2022. Figure 1.

If immediate write mode is selected on the Section 4.5, then changes made in the selection boxes will be written to the HDC2022 device as soon as possible. The Auto Measurement Mode, Temperature/Humidity Resolution, Measurement Configuration, activate Soft Reset, and Activate Heater widgets perform the same functions as on the Data Capture tab (refer to Section 4.2.) The other widgets are described below: • • • • • • DRDY/INT_EN Pin Configuration: Selects the output for the HDC2022 interrupt pin Interrupt Polarity: Selects the active/inactive state of the HDC2022 interrupt pin Interrupt Mode: Sets the behavior of the HDC2022 interrupt pin. Humidity/Temperature Offset: Sets the value of respective offset register within the HDC2022. Humidity/Temperature Threshold: Sets the value of the threshold registers within the HDC2022. HDC2022 Interrupt/DRDY Configuration Enable Bits: Selects the source of the HDC2022 Interrupt. Figure 7.

The Auto read drop-down box configures the rate of polling the register contents. When Auto-Read is off, it is necessary to click Read Register to fetch the contents of the current register. Read All Registers can be used to fetch the contents of all registers at once. The Write Register buttons are disabled when the drop-down next to these buttons is set to immediate mode. Immediate mode will trigger a write operation each time a register is modified. When deferred mode is selected, the write register button is enabled, and write operations will be performed only when the write register button is clicked. These settings give the user control over I2C bus activity, and enable individual transactions which can be easily observed via oscilloscope, logic analyzer, or bus-sniffing device. Figure 8.

Figure 10. HDC2022EVM 5.1 5.1.1 Input/Output Connector Description J1 & J2 – 5x1 Headers These headers are not populated and can be installed if the EVM is broken in two sections: PC interface and Sensor. J1 and J2 allowfor communication of the two sections using a 5-wire cable.The plated through-holes may also be used as a point to probe these signals during EVM operation. 5.1.2 Jx.1 GND Jx.2 SDA Jx.3 SCL Jx.4 INT Jx.5 VDD USB Type A Connector This connector is used for communications with the PC and provides power for the EVM. 5.2 EVM Operating Conditions The HDC2022EVM power is supplied via the USB connector. The LDO (U4) converts the 5V from the USB to 3.3V used by the HDC2022 and the MSP430. The EVM may be directly inserted into a USB port on a PC or laptop, or may be connected to the latter using the appropriate USB cable. The controller and device sides of the EVM have different temeperature limits as shown in Table 2. These are set by the onboard MSP430F5528 and the HDC2022 ICs on the controller and breakout portions respectively. Table 2.

This is done by setting the ADDR pin to VDD via a 0 ohm resistor (R4) (refer to Figure 11). Figure 11. HDC2022EVM : Sensor Module To change the I2C address to 0x40, remove 0 Ω resistor R4 (refer to Figure 12 ). Figure 12. HDC2022EVM: Layout Resistors for I2C Address Setting - Top Table 3.

Figure 13 shows the board perforations that allow the two sections to be broken apart. Figure 13. HDC2022EVM: PC Interface and Sensor Module The communication between the two modules is ensured through the connector J1 and J2 and a 5-wire cable. In this configuration the thermal mass of the EVM is dramatically reduced, improving the temperature measurements performances of the HDC2022. The cable connecting J1 to J2 must conform to I2C cable length constraints. When used in this configuration, the GUI can still be used to communicate with the EVM and collect data. If the thermal mass of the sensor section is still excessive, the sensor section can be reduced by breaking it at the perforation shown in Figure 14. The PCB segment that hosts the HDC2022 is 5.5mm x 5mm. Figure 14. HDC2022EVM: PC Interface and Smaller Sensor Module Also in the case where the EVM is broken into two sections it is still possible to use the GUI (ensuring the connections between the modules) or alternatively it is possible to connect the sensor module to a custom micro-controller.

The primary method for flashing the HDC2022EVM is Spy-Bi-Wire. In order to reflash the firmware you will need the following: • PC • HDC2022EVM to be flashed • MSP-EXP430F5529LP and included USB connection cable • 3 x Male to Female Jumper Cables • UniFlash (Offline or Cloud Version) – Install Offline version from: http://www.ti.com/tool/UNIFLASH – Cloud version is accessible here: http://dev.ti.com/gallery/ To update the firmware on the HDC2022EVM complete the procedure below: 1. 2. 3. 4. Plug in the HDC2022EVM to the PC via USB Connector to provide power to the EVM. Connect another USB cable to the MSP-EXP430F5529LP Remove the SBW RST and SBW TST Jumpers on the MSP-EXP430F5529LP board Create a wiring harness by connecting jumpers to SBW RST, SBW TST, and GND on the MSPEXP430F5529LP. 5. Insert the male end of the jumpers through the SWBTCK, SBWTDIO, and GND through holes on the HDC2022EVM. These are shown in Figure 16. Make these connections as follows: • SBW RST ↔ SBWTDIO • SBW TST ↔ SBWTCK • GND ↔ GND Figure 16. HDC2022EVM Spy-Bi-Wire programming connections 6. Open UniFlash. 7.
