Programmer Circuit for EEPROM on MDM-DEV-1.
Good tutorial on the 877 and how to use the hardware features, includes some C software. This information was on www.andrew.cmu.edu/user/
apangar/pic but this link is broken. Download these 4 files L1, L2, L3 & L4.
|The datasheets for the MDM-1 and MDM-DEV-1 are good sources of hardware information. Even if you are only buying a MDM-1 the dev board datasheet is packed full of usefull technical information and circuit configurations. In addition don't forget the MDM-1 software applications. If you are buying the dev board then all this comes with it anyway. Remember you do need to buy a programmer, follow the link below.

On-line book which although based on the older Pic's is worth reading.
