Hi, Recently I bought a atmega8 development board from futurlec/mrt. This board has it's own, yet another idea how the isp connector and (parallel) programming cable (labeled AT-ISP V1.1) looks like. There's also a windows software supplied to program the uC.
All signal lines between the isp connector and atmega8 (reset, sck, mosi, miso) are inverted with a 74ls04. Since all IC components are installed in a socket, I was able to bypass the inverters, by inserting wires in the ic socket of the 74ls04 (creating a pin compatible 'passive non-inverting device' ;-)). With the following added to /etc/avrdude.conf, I was able to program the atmega8: programmer id = "atisp"; desc = "AT-ISP V1.1 programming cable for AVR-SDK1 from micro-research.co.th"; type = par; reset = 6; sck = 8; mosi = 7; miso = 10; ; My questions are: - Is anyone using this board successfully with avrdude? - Would it be possible let avrdude invert the programming signals, so that a board like this would be directly supported? The avrdude.conf file might then, for example look like: programmer id = "atisp"; desc = "AT-ISP V1.1 programming cable for AVR-SDK1 from micro-research.co.th"; type = par; reset = _6; sck = _8; mosi = _7; miso = _10; ; Using some character (_) to invert a pin.
