3.1 Programming with mikroBootloader You can program the microcontroller with a step 1 – Connecting clicker 2 for PIC32MZ 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: download.mikroe.com/examples/starter-boards/clicker-2/ pic32mz/clicker-2-pic32mz-mikrobootloader-usb-hid-v100.zip 1 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 clicker 2 for PIC32MZ PIC32MZ clicker2 for PIC32.hex HEX.file 1 1 2 Figure 3-4: Selecting HEX Figure 3-3: Browse for HEX 1 Select .HEX file using open dialog window. 2 Click the Open button.
step 4 – Uploading .HEX file clicker 2 for PIC32MZ clicker 2 for PIC32MZ PIC32MZ PIC32MZ PIC32MZ Begin uploading 1 1 Figure 3-5: Begin uploading Figure 3-6: Progress bar 1 To start .HEX file bootloading click the 1 Progress bar enables you to monitor .HEX file uploading. Begin uploading button.
step 5 – Finish upload PIC32MZ.hex 1 PIC32MZ.hex Figure 3-7: Restarting MCU Figure 3-8: mikroBootloader ready for next job 1 Click OK button after the uploading process is finished. 2 Press Reset button on Clicker 2 for PIC32MZ board and wait for 5 seconds. Your program will run automatically.
3.2 Programming with mikroProg programmer The microcontroller can be programmed with external mikroProg for PIC, dsPIC, and PIC32 programmer and mikroProg Suite for PIC32MZ software. The external programmer is connected to the development system via 2x5 connector Figure 3-9. mikroProg is a fast USB 2.0 programmer with hardware debugger support. It supports all PIC, dsPIC, and PIC32 devices in a single programmer. Outstanding performance, easy operation and elegant design are its key features.
mikroProg Suite for PIC32MZ software PIC32 mikroProg programmer requires special programming software called mikroProg Suite for PIC32®. This software is used for programming of ALL Microchip® microcontroller families, including PIC10®, PIC12®, PIC16®, PIC18®, dsPIC30/33®, PIC24® and PIC32®. Software has intuitive interface and SingleClick programming technology. Just by downloading the latest version of mikroProg Suite your programmer is ready to program new devices.
4. Buttons and LEDs The board also contains a 1 reset button and a pair of 2 buttons and 3 LEDs, as well as an ON/OFF switch. The Reset button is used to manually reset the microcontroller — it generates a low voltage level on the microcontroller’s reset pin. LEDs can be used for visual indication of the logic state on two pins (P34 and P18). An active LED indicates that a logic high (1) is present on the pin.
5. Power management and battery charger Clicker 2 for PIC32MZ features LTC®3586, a highly integrated power management and battery charger IC that includes a current limited switching PowerPath manager. LTC®3586 also enables battery charging over a USB connection.
6. Oscillators Two onboard oscillators act as external sources for PIC32MZ’s two system clocks. A 24 MHz oscillator provides a reference frequency output to the clock multiplier PLL. A a 32.768kHz oscillator provides a clock for the internal RTCC. Figure 6-1: 32.
7. USB connection PIC32MZ microcontrollers has an integrated USB module, which enables you to implement USB communication functionality to your Clicker 2 board. Connection with target USB host is done over a micro USB connector which is positioned next to the battery connector.
