Hi everybody !!! I've got a problem with my Nordic nRF24E1. It's a powerful transceiver with an integrated 8051 microcontroller (Dallas DS80C320). It has only 4KBytes of internal program memory. The trouble is that I've a program of 16KBytes located in an external EEPROM of 32Kbytes.I think that my sole solution is memory paging. But I don't know how to switch between pages and I don't know when I must do it. Does anyone know techniques for memory paging with 8051 ? If you have another solution than memory paging, I'm very interested... Thanks Regards Corentin Briat
In other words, I need to load the program code from the external EEPROM (of 32KBytes) into the internal memory by blocks of 4KBytes because the internal memory size is 4KBytes. 1) buy a jumbo bottle of aspirin 2) work on it 3) give up and install a parallel code memory. Erik
If the uC is socketed on the board, why not just replace it with a capable derivative. E.g. The Philips p89c668 has 64k code flash and 8k data RAM, but there are plenty of other choices. If it is soldered, maybe you can still replace it. Erik
