Hi Sir ,

Im planning to build SPI communication  using Arduino Uno for W25Q80 SPI memory chip .

Here i  receive 512 bytes of binary data from serial port and that i need to save it in W25Q80 memory chip using SPI interface and same will be retrieved from memory chip and print  it in serial port .


I tried for example code for my requirement but i did not get it  , Can you please suggest or  link me to the right code sample for my requirement  .


Thanks in advance for the support ..!!

With a 64 byte serial buffer, you need to be very careful that you read the data faster than it arrives, so you don't allow overflow to happen. The code you posted doesn't show that happening.

Why? Why doesn't the sender simply remember what it sent?
