7 1. Power supply Battery power supply Figure 1-1: Connecting USB power supply You can also power the board using a Li-Polymer battery, via onboard battery connector. On-board battery charger circuit enables you to charge the battery over USB connection. LED diode (RED) will indicate when battery is charging. Charging current is ~300mA and charging voltage is 4.2V DC.t USB power supply Figure 1-2: Connecting Li-Polymer battery You can supply power to the board with a micro USB cable provided in the package. On-board voltage regulators provide the appropriate voltage levels to each component on the board. Power LED (GREEN) will indicate the presence of power supply. NOTE Some click boards need more current than the USB connection can supply. For 3.3V clicks, the upper limit is 750 ma; for 5V clicks, it s 500 ma. In those cases you would need to use the battery as the power supply, or the vsys pin on the side of the board. Page 7

This 16-bit microcontroller features large dual partition flash with live update capability. This family includes up to 1024KB Flash, 32KB RAM, USB and advanced peripherals. Key MCU features CPU speed: 16 MIPS Architecture: 16-bit Program memory: 1024KB Pin count: 100 USB v2.0 On-The-Go (OTG) Compliant Page 8

9 3. Programming the microcontroller Figure 3-1: PIC24FJ1024GB610 microcontroller The microcontroller can be programmed in two ways: Using USB HID mikrobootloader, Using external mikroprog for PIC24 programmer Page 9

10 3.1 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 clicker 2 for PIC24 clicker-2/pic24/clicker-2-pic24-bootloader.zip After the mikrobootloader software is downloaded, unzip it to desired location and start it. 01 clicker 2 for PIC24 Bootloader WinRAR ZIP archive clicker 2 for PIC24 Bootloader File folder Software File folder mikrobootloader USB HID.exe Bootloader tool for mikroelektron... mikroelektronika Firmware File folder clicker 2 for PIC24 PIC24FJ1024GB610 USB HID Bootloader v2.700.hex HEX File 01 Figure 3-2: USB HID mikrobootloader window To start, connect the USB cable, or if already connected press the Reset button on your clicker 2 for PIC24. Click the Connect button within 5s to enter the bootloader mode, otherwise existing microcontroller program will execute. Page 10

Select.HEX file using open dialog window. Click the Open button. Page 11

12 step 4 Uploading.HEX file Begin uploading 01 Figure 3-5: Begin uploading Figure 3-6: Progress bar To start.hex file bootloading click the 01 Begin uploading button. Progress bar enables you to monitor.hex file uploading. Page 12

13 step 5 Finish upload 01 Figure 3-7: Restarting MCU Figure 3-8: mikrobootloader ready for next job Click OK button after the uploading process is finished. Press Reset button on clicker 2 for PIC24 board and wait for 5 seconds. Your program will run automatically. Page 13

14 3.2 Programming with mikroprog programmer The microcontroller can be programmed with external mikroprog for PIC programmer and mikroprog Suite for PIC software. The external programmer is connected to the development system via 1x5 connector Figure 3-9. mikroprog is a fast USB 2.0 programmer with hardware debugger support. It supports PIC10, dspic30/33, PIC24 and PIC32 devices in a single programmer. It supports over 1100 microcontrollers from Microchip. Outstanding performance, easy operation and elegant design are its key features. You can also program it with ICD2 or ICD3 if you reroute the wires like shown here. 1. NC 2. PGC 3. PGD VCC 3.3V 6.

15 mikroprog Suite for PIC24 software PIC24 mikroprog programmer requires special programming software called mikroprog Suite for dspic. 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. mikroprog Suite is updated regularly, at least four times a year, so your programmer will be more and more powerful with each new release. Figure 3-10: Main window of mikroprog Suite for dspic programming software Page 15

16 4. Buttons and LEDs The board also contains a 01 reset button and a pair of 02 buttons and 03 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 (RG13 and RE8). An active LED indicates that a logic high (1) is present on the pin. Pressing any of the two buttons can change the logic state of the microcontroller pins (T2 and T3) from logic high (1) to logic low (0). Figure 4-1: Two LEDs, two buttons and a reset button Page 16

17 5. Power management and battery charger clicker 2 for PIC24 features LTC , 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. Figure 5-1: power management and battery charger IC Page 17

18 6. Oscillators Board is equipped with 8MHz crystal oscillator (X1) circuit that provides external clock waveform to the microcontroller CLKO and CLKI pins. This base frequency is suitable for further clock multipliers and ideal for generation of necessary USB clock, which ensures proper operation of bootloader and your custom USB-based applications. There is also KHz crystal oscillator for the RTC Figure 6-1: 8MHz crystal oscillator module (X1) and KHz crystal oscillator Page 18

19 7. USB connection PIC24 microcontrollers have 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. Figure 7-1: Connecting USB cable to clicker 2 Page 19
