Parallel Programmer

[myplasticegg]

I have made my programmer using this method ( Arduino - ParallelProgrammer ) but I am not sure where to hook it up on my spiffie kit MPGuino. I see 4 sets of 2 jumpers (8 total) near the buttons... where else could it go?

thanks, Shane

You probably need an isp connector for that programmer (2x6). The spiffie should be programmable with a standard usb cable though, like hooked to most printers/scanners these days.

yeah, I had the resetting issue and it won't boot up now. I've tried to upload a new sketch, can't find it. Need to re-boot it.

You can rig up connections to the appropriate isp pins on the cpu with whatever you have handy. Here is a schematic that has the isp mapping:

I made an "in circuit" adapter for my ftdi cable out of an extra DIP socket (plus hotglue and careful bending of the tips, reset cap, etc, etc). I just press it on while programming. Maybe rig something like this up if you plan on doing it more than once.

Sorry for the stupid question, but what pins are what on the ATML chip. I know what numbers to tap into, but the chip itself isn't numbered.

Thanks, Shane

for isp, MOSI, MISO, SCK, Reset, +5(VCC), GND

I have everything hooked and i open the code in arduino 0011 Alpha (is this the right program?) It gives me an error;

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

I have tried to run it with USB powering it and without.

yah, the parallel guy is flakey in my experience. I wound up loading a bootloader and verifying that it worked by watching for the blinking.

Those errors mean that the ATmega bootloader is not responding to avrdude.

Is the chip dead or should I try get a better connection to the chip with the bootloader? I need to get this thing going again ASAP as it is graded.
