4. Programming the microcontroller Figure 4-1: STM32F415RG microcontroller The microcontroller can be programmed in two ways: 01 Using USB HID mikroBootloader, 02 Using external mikroProg™ for STM32 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: step 1 – Connecting STM32 M4 clicker www.mikroe.com/downloads/get/2144/ mikrobootloader_usb_hid_STM32F415RG.zip 01 After the mikroBootloader software is downloaded, unzip it to desired location and start it.
step 2 – Browsing for .HEX file step 3 – Selecting .HEX file 01 01 02 Figure 4-3: Browse for HEX Figure 4-4: Selecting HEX 01 Click the Browse for HEX button and from a pop-up window (Figure 3.4) choose the .HEX file which will be uploaded to MCU memory. 01 Select .HEX file using open dialog window. 02 Click the Open button.
step 4 – Uploading .HEX file 01 01 Figure 4-5: Begin uploading Figure 4-6: Progress bar 01 To start .HEX file bootloading click the Begin uploading button. 01 Progress bar enables you to monitor .HEX file uploading.
step 5 – Finish upload 01 Figure 4-7: Restarting MCU Figure 4-8: mikroBootloader ready for next job 01 Click OK button after the uploading process is finished. 02 Press Reset button on STM32 M4 clicker board and wait for 5 seconds. Your program will run automatically.
Programming with mikroProg™ programmer Figure 4-9: mikroProg™ connector The microcontroller can be programmed with external mikroProg™ for STM32 programmer and mikroProg Suite™ for ARM® software. The external programmer is connected to the development system via 2x5 JTAG connector soldered on the CN2 connector pads, Figure 4-9. mikroProg™ is a fast USB 2.0 programmer with hardware debugger support. It supports STM32 M3 and M4 devices from STMicroelectronics.
mikroProg Suite™ for ARM® software On-board mikroProg™ programmer requires special programming software called mikroProg Suite™ for ARM®. This software is used for programming of all supported microcontroller families with ARM® Cortex™-M3 and Cortex™-M4 cores. The software has an intuitive interface and SingleClick™ programming technology. To begin, first locate the installation archive on the link bellow: http://www.mikroe.com/downloads/get/1809/mikroprog_suite_for_arm.
Programming with ST-LINK V2 programmer In order to adjust the ST-LINK™ V2 programmer to be connected to the development system, it is necessary to provide the appropriate adapter such as the mikroProg to ST-LINK V2 adapter. 2x5 male headers should be first soldered on the CN2 connector pads. Then you should plug the adapter into the ST-LINK V2 programmer (2x10 header), and plug an IDC10 flat cable in headers, Figure 4-12.

5. Buttons and LEDs 01 02 03 Figure 5-1: Two buttons, two LEDs and a reset button 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).

6. RTC battery STM32 M4 clicker features RTC battery pads for powering microntroller’s internal RTC module. Battery is used as an alternative source of power, so the RTC module can keep track of time while primary source of power is OFF or unavailable. In order to use this option it is necessary to connect (solder) external battery (type CR2032; voltage range from 1.65 to 3.6 V) and unsolder jumper J1, Figure 6-1.
