I've been experimenting with the AVR protocol in waveforms on the electronics explorer, and I've been getting some weird results. For most speeds the board is not identified correctly, and for the speeds that do work, verification always fails after writing flash. The connection is sometimes stable enough to read/write fuses. I've tested with a few boards (2 attiny85, 2 atmega328p). All of them program fine with other ISP options.
I imagine I'm just doing something wrong, so could anyone point me in the direction of some resources? My simplest test case is just an ATtiny85 connected to 5v or 3.3v with the ISP wires connected directly. The internal clock is 16MHz and I checked it's calibration.
