PIC 16F84 Serial Programmer
Kees Krijnen writes:The Microchip PIC16C84 was one of the first serial in-system programmable microcontroller. I saw PIC serial programmers published in Electronic magazines in 1993. Today, many PIC programmer circuits - for serial and parallel PC ports - are published on the Internet.Despite its somewhat unusual design - like the 128 byte page RAM/Register direct/indirect memory mapping - it is a popular microcontroller, easily available and programmable now as flash microcontroller 16F84. The developer environment MPLAB from Microchip is free of charge and many application examples are available.
