deʃhipuThe ATmega8 chips arrived, and I decided to try and see if my servo controller code will run on it equally well as on the ATmega328p that I used previously. After soldering it to the PCB (I'm getting better at it) I edited the Makefile to change the target, ran it and... got errors. Looks like a couple of registers got renamed, so I took the datasheets, compared them and made the appropriate changes. This time it compiled, so I flashed it to the chip, and... it doesn't work. I looked again, and realized that the fuses are completely different for this chip! To the avr fuse calculator. I changed the fuses in the makefile, flashed again and... it works!
I still need to properly debug and finish the Python code for walking -- the last weeks were a bit too busy to setup the testing and focus on this properly, but I hope I will get it done soon.
By the way, I also received the PCB for the #SpiderWing -- the Feather version of this. I'm going to be developing them both in parallel for now.

I ported some ATmega328 code to the ATmega8, and I agree that maintaining a portable version of the code requires some attention. At $0.50/piece the ATmega8 is a good µC. If you ever need something that's even cheaper (and no less capable) you may want to have a look at the STM8S003F3.

Looks interesting. I ordered a bunch and will try to setup a dev environment when I have a free moment -- however, this is actually the largest cost for me, the time investment needed.

The value of the time spent on building a development platform can't be underestimated :-) Keep it up!
