Dear Sir,
I am using ADUC841 microcontroller from Analog devices,which consists of 8052 core.In this it is having 4Kbytes of Flash data memory.I wrote the routines as mentioned in application note for writing the data in Flash.But the data is not storing in Flash.So,please send me some guidelines for writing the data in Flash.
Thanking you,
Yours sincerely, Shivakumar Manda
I had read the datasheet and according to that only i wrote one simple program to store the bytes in one page.Here I am sending the function statements to write the bytes in data memory.
void Flash_Mem_Write_Page(void) { EADRH=0x00; //Select Address hoiher byte EADRL=0x01; //Select addres lower byte
EDATA1=0x12; //writing the data EDATA2=0x13; EDATA3=0x14; EDATA4=0x15;
ECON=0x02; //writing the bytes Sleep(40); ECON=0x04; //verifying Sleep(22);
if(!ECON) //match is there it will return 0in ECON printf("WRITE\n"); else printf("NOT WRITE\n"); }
Thank you very much for replying.
"I had read the datasheet"
I hope you read it more carefully than the instructions here for posting source code:

You also, apparently, didn't notice the problem in the 'Preview' - I hope you've reviewed your own code more carefully?
