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 (PE12 and PE15). An active LED indicates that a logic high (1) is present on the pin.

9.1 mikroBUS™ pinouts clicker 2 for PIC18FJ employs a solution to optimize the use of available pins and MCU I/Os. The PWM SEL jumper (Figure 9-2) enables two modes of use for the second available PWM line: 1 The default position of the jumper is for applications when you’re not using the PWM line on the 1x26 pinout on the right side of the board. This keeps this PWM available through mikroBUS™ 2 If you resolder the jumper into the second position, it would turn the PWM line on mikroBUS™ 2 into a GPIO.
10. click™ boards are plug and play! Up to now, MikroElektronika has released more than 90 mikroBUS™ compatible click™ boards. On the average, one click board is released per week. It is our intention to provide you with as many add-on boards as possible, so you will be able to expand your development board with additional functionality. Each board comes with a set of working example code.
