The project i am working is as below:

I got ADuC7061's USART is connected with PIC18F46j50 EUSART. the aduc7061 continously transmits an information and the pic18f receives that information through its eusart0.

Now the question is that I have to store that information on pic18's eeprom and then display that information after some manipulation onto 128x64 graphics display.

Answer 1

The PIC18F46J50 does not have integrated EEPROM memory. You have two alternatives:

• Use a PIC which contains EEPROM memory. See http://www.microchip.com/ParamChartSearch/chart.aspx?branchID=1004&mid=10&lang=en&pageId=74 for a product selection table.

• Use the program flash memory. This has some drawbacks like less number of maximum write cycles compared to EEPROM and only bank-wise erasure, but might be sufficient depending on your requirements. See also Emulating Data EEPROM for PIC18 and PIC24 Microcontrollers
