I am doing a personal GPS and I use the PIC18F26J11, connect the GPS and the SIM800 and use a 26C16 memory to store the telephone numbers, but I would like to use an SD(FAT) memory, I see that it is not equal to the recording and reading of an eeprom memory, someone has a example to record one number of 6 or 8 digit in an SD memory and read them when required
The examples in wiki are somewhat confusing for me and there is no one that shows how to record the number in the SD and call it when needed and in the forum I did not find any example. . .
Thanks
Enrique
