Hi I searched the net to find out how I can write into lpc2000 internal EEPROM I found some for other devices but nothing for lpc2000, I even doubt if lpc2000 has internal EEPROM! Can anyone help me figure out how I can read and write to internal EEPROM of lpc2388 if it has any such memory?
Yeah, it seems I have to use IAP to write in flash or use the battery backed up SRAM I am studying for writing in flash right now, but don't have any idea how to write in the battery backed up SRAM How can I tell the compiler (Keil uVision 4.2) that a variable should be stored in battery backed up SRAM
Define the memory region it occupies in the Target dialog or scatter file, and use #pragma's or directives to use specific segments, or reference the variables/objects in the scatter file?
I'd imagine you can also access it like any other memory in the address space, you could also use pointers and structures to manage the data you put in NV memory.
It might be helpful for you to review the technical documentation for the tool chain and become more familiar with the options and controls available.
Thanks I looked at keil uVision example for MCB2100 IAP code I have 2 more questions 1. Do I have to disable PLL before I enter IAP code 2. I understood how to write from RAM to Flash, but how can I read back from Flash to RAM? Somewhere was suggesting to use XDATA banking to read from flash and store it in RAM, but I couldn't understood how XDATA banking works and whther there is an easier solution for reading from FLASH
Thanks again for your kind response
