I have a Sprkfun serial 7 segment display (pn COM-11442 ) and would like to reprogram the Atmel328 chip with a dedicated application.
The examples on the website seem to be about programming a Uno to send messages via UART, SPI or I2C and although there is a mention of reprogramming the embedded 328 details would appear to be missing. Is there a URL with such information or can some kind person guide me.
I am quite comfortable at programming an Arduino Uno from a PC either via the USB serial or via the ICSP header and a USBasp to replace the bootloader.
I have added the 7 segment display to the board types supported, but cannot find any information on how to connect up the programmer to the board. What do I select as the programmer and what do I connect it to. There does not appear to be an ICSP header so no idea how to re-flash the bootloader.
Do I need to wire up the ICSP direct onto the ATmel chip pins?
Thanks
Peter
