Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

A little costly(MHO only), but it would be a nice simple plug-and-play solution.

EDIT: My QFP chips have arrived.

They look like they won't be too difficult to solder with 0.8 pin spacing - famous last words...

My 44-pin QFP boards have arrived, so I will try to get one soldered up ASAP, so I can then try the 44-pin firmware.

Well, I have managed to solder my first QFP - not as hard as I thought it would be.
Thanks mainly to EV Blog's excellent YouTube videos with nice close up shots, I was quite well prepared. It all went exactly as he said in his video - the only hard part, was getting the chip correctly aligned on the footprint - that was tricky - breath out, and it moves a fraction of a mm!

However, I now have my QFP on my prototyping PCB, and so now I can set about loading in the 44-pin HEX.
