As TDK has mentioned: buffering a larger amount of data helps a lot. Make it a multiple of a sector size (N * 512 bytes). The drawback: you need larger memory (RAM) on MCU and the data sits still just in memory until you write it back (you flush the temporary buffer to...
I have a UART interrupt filling a circular buffer. The CCS code �hangs� the PIC while waiting for the EEPROM write to finish, that�s 8ms of time in my application, at 9600 baud I will miss 6 bytes!!!. The CCS code uses the technique of waiting until the WR Write Control ...
Hello, I need to write the data received by the UART into the EEPROM. I don't understand how to write the instructions. Can you help me? Thank you. /* * main implementation: use this 'C' sample to create your own application * */...

Summary of Problem I am trying to communicate through UART with an E32 TTL 100 LORA module from a Raspberri Pi 3 B+. When I write to the port there is no error but the call doesn't return. Apparently it enters an infinite loop and the bl...
