MK22FN512VLH12 microcontroller The Kinetis clicker development tool comes with the MK22FN512VLH12 microcontroller. This 32-bit high performance microcontroller is rich with on-chip peripherals and features 1024KB of Flash and 192KB of SRAM. It has integrated full speed USB 2.0. support. Key microcontroller features: ◾ ◾ ◾ ◾ ◾ ◾ ◾ Up to 120 MHz operation (1.25 Dhrystone MIPS per MHz) 32-bit ARM® Cortex®-M4 architecture 512KB of Flash memory 128KB RAM 2x SAR 16-bit ADC, 2x 12-bit DAC Two crystal oscillators: 32 kHz (RTC) and 32-40 kHz or 3-32 MHz USB OTG, 3x UART, 2x I2C, 2x SPI, etc. Programming The microcontroller can be programmed in two ways: 1) Using USB HID mikroBootloader, 2) Using external mikroProg™ for Kinetis programmer. Programming with mikroBootloader You can program the microcontroller with a bootloader which is preprogrammed by default. To transfer .hex file from a PC to MCU you need bootloader software (mikroBootloader USB HID) which can be downloaded from: www.mikroe.com/kinetis/clicker-2 After the mikroBootloader software is downloaded, unzip it to desired location and start it. step 1 – Connecting Kinetis clicker To start, connect the USB cable, or if already connected press the Reset button on your Kinetis clicker. Click the Connect button within 5s to enter the bootloader mode, otherwise existing microcontroller program will execute. step 2 – Browsing for .HEX file Click the Browse for HEX button and from a pop-up window choose the .HEX file which will be uploaded to MCU memory. step 3 – Selecting .HEX file Select .HEX file using open dialog window. Click the Open button. step 4 – Uploading .HEX file To start .HEX file bootloading click the Begin uploading button. Progress bar enables you to monitor .HEX file uploading. step 5 – Finish upload Click OK button after the uploading process is finished. Press Reset button on Kinetis clicker board and wait for 5 seconds. Your program will run automatically. Page 3 of 3 Programming with mikroProg™ programmer The microcontroller can be programmed with external mikroProg™ for Kinetis programmer and mikroProg Suite™ for ARM® software. The external programmer is connected to the development system via 2x5 JTAG connector soldered on the CN3(TKDARKO) connector pads. mikroProg™ is a fast USB 2.0 programmer with hardware debugger support. Outstanding performance, easy operation and elegant design are its key features. mikroProg Suite™ for ARM® has an intuitive interface and programming technology. First, download the software from MikroElektronika's webpage (http://www.mikroe.com/downloads/get/1809/mikroprog_suite_for_arm_v132.zip). After downloading, extract the package and double click the executable setup file, to start the installation. Click the Detect MCU button in order to recognize the device ID. Click the Read button to read the entire microcontroller memory. You can click the Save button to save it to the target HEX file. If you want to write the HEX file into the microcontroller, first make sure to load the target HEX file using the Load button. Then click the Write button to begin programming. Click the Erase button to clear the microcontroller memory. Oscillators The MK22FN512VLH12 microcontroller is equipped with internal 32 kHz, 4 MHz and 48 MHz references that provide a stable clock signal. Since the chips have an integrated PLL, this base frequency is suitable for further clock multiplication. The board also contains an additional 8MHz crystal oscillator, as well as a 32.768kHz one, which provides an external clock for the internal RTCC module. Buttons and LEDs The board also contains a 01 reset button and a pair of 02 buttons and 03 LEDs. Each of these additional peripherals are located in the bottom area of the board. Reset button is used to manually reset the microcontroller. Pressing the reset button will generate a low voltage level on microcontroller’s reset pin. LEDs can be used for visual indication of the logic state on two pins (RA0 and RA1). An active LED indicates that a logic high (1) is present on the pin. Pressing any of these buttons can change the logic state of the microcontroller pins (RD2 and RD3) from logic high (1) to logic low (0) Resources - Kinetis MK22FN512VLH12 data sheet (http://cache.nxp.com/files/microcontrollers/doc/data_sheet/K22P121M120SF7.pdf) - mikroProg Suite for ARM direct download (http://www.mikroe.com/downloads/get/1809/mikroprog_suite_for_arm_v132.zip) - USB HID bootloader for Kinetis clicker (http://www.mikroe.com/downloads/get/2574/kinetis-clicker-bootloader.rar) - Kinetis K22 overview on NXP.com (http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/kinetis-cortex-m-mcus/k-seriesperformance-m4/k2x-usb/kinetis-k22-120-mhz-cost-effective-full-speed-usb-microcontrollers-mcus-based-on-arm-cortex-m4-core:K22_120) Retrieved from "http://docs.mikroe.com/index.php?title=Kinetis_clicker&oldid=437" ◾ This page was last modified on 20 June 2016, at 18:20. ◾ Content is available under Creative Commons Attribution unless otherwise noted. http://docs.mikroe.com/index.php?title=Kinetis_clicker&printable=yes 7/11/2016
