MicrochipEdit

We intend to use the PICKit 2 programmer from the workshop, with the PIC16F690 from Microchip. We will program it using MPLAB, probably in C. Datasheet

Explanation about what "weak pull up" means in datasheet

ICSP - In Circuit Serial Programmer

MCLR - Master Clear - Spikes in the power supply can freeze up a PIC or cause erratic behavior. Most PICs have an MCLR function that causes a full reset when this happens. To use this function, put a 10K resistor (R1) between the power supply and the MCLR pin.

Programming Voltage - First, the programming voltage is raised (VPP) to put the PIC in programming mode. Next, the data line is changed to reflect the value 0 or 1. A clock pulse is applied to copy the data pin value into the PIC. When all the data has been copied, the VPP is removed.
