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

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 570 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 dspic software dspic 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 (RA0 and RG9). 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 dspic33 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 OSC1 and OSC2 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. And the 32. TK MHz oscillator (X2), a Real-Time Clock and Calendar (RTCC) module. Figure 6-1: 8MHz crystal oscillator module (X1) and KHz crystal oscillator Page 18

19 7. USB connection dspic33 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. Figure 7-1: Connecting USB cable to clicker 2 Page 19
