Posted on September 12, 2012 at 11:25Dear friends,
I'm using the eeprom emulation STM32F2xx_AN3390_FW_V1.0.0 for saving the configuraiton. I make some test code to understand the source code, I can test with 3 varibles with address 0x5555, 0x6666, 0x7777. But after I increase NB_OF_VAR ((uint8_t)0x05) and my souce code testing below. I read the value of address 0x8888 and 0x9999 are always zeros. I was wondering that friends can give me a helpl
uint16_t VirtAddVarTab[NB_OF_VAR] = {0x5555, 0x6666, 0x7777, 0x8888, 0x9999};
