Hello folks !!I'm writing because I need some suggestions on how to upgrade the firmware on a SPI slave. In this scenario I have a .txt file which contains the bytes I need to send, via SPI protocol, to a SPI slave hardware. The best thing I have tought is to open the .txt and copy its content into a variable. The problem is that the firmware has 224 KB size for a total of about 57K element.. And I have to initialize the variable by hand.. element x element... Any suggestions ?? Thank you for help !!
