PIC

We live in an age of wonder... I can buy 32bit MIPS processor boards (aka PIC32) for $49. I am considering using one for my car computer project, but on this page at the moment I am only talking about using a PICKIT2 to control a keyboard.

The chips

What I have around right now

• PIC18F25K20 (28pin)
• PIC 16F873 (28pin)
• PIC 12F675 (8pin)
• PIC 12F683 (8pin)
• 24LC65 8Kx8 EEPROM
• 8 MHz ceramic resonators
• 4 MHz ceramic resonators
• 32kHz xtals for slow but very low power operation (button cell powered data collectors)

Development tools

Hardware

I am now using a PICKIT 2 purchased directly from Microchip. For $50 you get a development board, the programmer, and the software. http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en023805&redirects=pickit2

1/13/13 -- My recent foray was unsatisfying because I found my Pickit 2 does not support the 16F690 for debugging with the C compiler, even though it's the chip on the Pickit 2 board... I am setting up a breadboard with a 16F873 I had in my junk box. Hope it works.
