PowerPIC Hardware

The PowerPIC is built on a PIC16LF19197 with 56KB of flash memory and 4KB of RAM. Required features included: a real time clock and calendar module for timekeeping, a LCD controller for driving the stock Casio display, and a 10-bit PWM for driving the piezo buzzer. Some additional useful features are: a 12-bit ADC for roughly determining battery level, and a temperature sensor for roughly gauging temperature.

The only other components besides the required passives are a 32.768kHz crystal, and a LED that is used for the backlight.

Changelog

Version 2.0 - Added experimental backlight. - Added RTC crystal for accurate timekeeping.

Version 1.1 - Switched buzzer from RF0 to RG7 so we can use the PWM peripheral. - Switched keypad rows to RA0-RA3. Row 1 was using RA5 which is VBAT and unusable as digital output - Added additional test points for the side buttons, allowing buttons to be simulated for development - Added additional GND test point

Version 1.0 - First hardware version
