But why why why an stm32. A mega 256 will do the job too for a 2cv including sequential injection and ignition. Stm32 is onla a big pain in the ass.

I did ignition on a mega328 and with a second board with the lpg injection too. Never failed on me in 9 years. I'm thinking to do a simimilar board 2x2 sequential running on an Atmega 1284 and my own software. I have the schematc ready so far.

Faster clock speed, and expandable memory. Trying to future proof a little.

This is on my own board, and does not have an MCU plug into it. The firmware supports STM32, but not so sure about the config of the F411. I will need to edit the FW to support my pinout and my selection for SPI mosi, miso etc.

I also need to add some chips via hot air soldering.

I wanted a really small board as well. Idea is to bolt it on to the points box, in a simular way to a 123.

First thing is to do is see if it works at all. :D

Production is complete, and I'm waiting for FedEx to pick it up from China :)
Should be here by the end of next week :D

Edit
Subject to Customs of course :)

Ok, so .... If you have 2 black wires, and one of them has a white line running down it. Which would you say was positive, and which negative?

Post Re: My Beduino
I bought some GS/GSA Alloy wheels for the Shed.

They won't fit straight off, as the trackrod end will foul the rim. This only happens when on lock, so the trackrod end is turning and coming into contact.

So, I will try a spacer. If that fails, I may need to see if there is enough metal to machine some off the rim. Though, I will look at the trackrod end as well.

The spacer will be the easier option, but means there is less thread on the wheel nuts.

Machining, I guess it's best to do all four wheels, so they are inter-changable.

Not sure about fitting to the back yet. :)

File comment: You can see by the black marks where it is fouling.

Just trying to make it a little tidier than it is. The trouble is, it keeps gaining on me! It's a bit like trying to polish a turd!

The fibreglass bonnet will help some. Though I do miss the bracket fungus that was growing out of the wooden one. :D

I think there is a little scope to remove 0.5 - 1.0 mm from the trackrod end. Doesn't have to be all the way round, and it's just on the corner. This will allow a thinner spacer on the wheel. :) And also keep the front and back wheels inter-changable.

Are AK trackrod (bit that bolts to the hub) arms shorter?

The whole build is good.
