PICBASIC PRO PROGRAMS FOR 18F4331:
Encoder Programs

These fundamental PicBasic Pro programs were written to introduce new statements that periodically would be combined into a program with a robotic application. Most of the programs are very short, focusing on one new command or a new application of a command. Check Technical Lessons for Year 2 for more background information.

The microcontroller used for the most part is the PIC16F88-I/P from Microchip Technology,
http://microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=64. The data sheet is available at: http://ww1.microchip.com/downloads/en/devicedoc/30487c.pdf. Jameco stocks the PIC16F88-I/P at a cost of $3.25 each for quantities less than 10. Microchipdirect lists the PIC16F88-I/P at $2.60 each for quantities less than 26.

Some of the programs have adapted to the PIC16F877A.

The programs are written in PicBasic Pro from micro-Engineering Labs, Inc., melabs.com. We prefer the melabs U2 Programmer over the EPIC Programmer. The cost for both the PicBasic Pro Compiler and the U2 Programmer with Accessories is $369.90 USD.
