I am using p89c52 phillips microcontroller chips with 4 kb flash memory. In a step of my project, I need to receive data from one microcontoller and store them in the flash memory of another so that i can view and use the data later.but I cannot do that as the flash memory included is a rom and there is no instruction to move the received data from micro controller (which comes into sbuf) to the code memory of that one.Can anyone suggest anything please? http://www.8051projects.net/forum-t10591.html 2009-01-07T17:55:40-08:00 Ajay P89C52 does not support In Application Programming (IAP) so you wont be able to use flash on runtime.
