Please do not modify the program firstly, and download the "UART-EEPROM.hex" directly to test "02-UART 1 reads and writes
EEPROM- using MOVC to read". Select the frequency 11.0592MHZ when downloading.
PC serial port setting: baud rate 115200,8,n,1.
Do sector erase, write 64 bytes, and read 64 bytes of EEPROM.
Command example:
E 0 Perform sector erasing operation on EEPROM, E means erasing, the number 0 is 0 sector (decimal, 0~126, see the specific IC).
W 0 Write operation to EEPROM, W means write, number 0 is 0 sector (decimal, 0~126, see the specific IC). Write 64 bytes continuously
from the start address of the sector.
R 0 Perform IAP read operation on EEPROM, R means read out, the number 0 is 0 sector (decimal, 0~126, see the specific IC). Read
64 bytes continuously from the start address of the sector.
M 0 Perform MOVC read operation on EEPROM (operation address is sector*512+offset address), number 0 is sector 0 (decimal,
0~126, see the specific IC). Read 64 bytes continuously from the start address of the sector .
Note: For general purpose, the program does not recognize whether the sector is valid or not, and the user decides according to the
specific model.
