Hi Everybody,
I have a program that reads data from the the main memory, and loads it to parameters.
Afterwards, i set some configurations and stores them back into the main memory, but it get stuck in the following lines:
for(i = 0; i < BAUD_MENU_LEN; i++) WriteToFlash((char*)MEM_L_BDRT - i,(char)L_BaudRate[i]);// Legal BaudRate
i comment those lines and try again, i load data from main memory and write it back, and read it again bu now it stucks again from the start of the loadparameters function.
this is the load and save parameters code:
#define MEM_CNTBY 0xFC00// Count_By
#define MEM_NOD 0xFBFF// NOD
#define MEM_DP 0xFBFE// Decimal_Place
#define MEM_BDRT 0xFBFD// BAUD RATE

#define MEM_ZERO_L 0xFBF5// ZERO LAST 16 BITS

#define MEM_MXWGT_L 0xFBF9// MAX WEIGHT LAST 16 BITS
