Hi all,
If I have an Atmega1280 connected to a MAX3421 USB Host Controller via SPI, am I going to have problems when I try to program the Atmega via the AVRISP mkII? I'm having a hard time seeing how the AVRISP mkII is able to 'select' the Atmega. The programmer connects to the standard SCK, MOSI, MISO, RESET, +5V, and GND on the Atmega, but the MAX3421 also connects to MOSI, MISO, and SCK.
Thanks for helping me understand this.
