if you use it for general spi com, run a a reset line to the 2313.

whenever my avr doesn't see any spi activity for a second or so, it plants the 2313, and everythings cool.

ok

bye

how do you use it for SPI general? I just plug it in and program with it, I dont see any option, the device is a SPI..its programmed with the SPI file.. it programs in that method, not big-bang port twiddling via Serial or Parrallel. it converts the usb to SPI as far as I understand?

get the code for avrdude. strip it down, and run it as a child process. that way, when it dies, youi just restart it.

easy for me to say. lol.
