Frequently asked questions
How do I program the PIC16F688?
Use a PIC programmer that supports in-circuit serial programming (ICSP), such as a PICkit or an equivalent, with Microchip's programming software. Plan the ICSP pins into your board layout.
Which pins can I use for analog input?
Only RA0, RA1, RA2, RA4, RC0, RC1, RC2 and RC3 can be used as ADC inputs, mapped to AN0 to AN7. Check the datasheet pin diagram before wiring sensors.
