Also Canada, few hours out of Toronto

I've been doing hardware and software engineering for a few years but I'm a lot better with hardware.
My partner is a software engineer, and we started a small business a while back. Not making any money right now, but hopping it'll pay for the tools eventually.

I just got a semi custom ECU using a Microsquirt Module running on a Stealth. The artificial software limitations of the uS pissed me off (same CPU as the MSII but omits a few features I needed).

So we've started looking into making one from scratch and found this project.

Has any thought been put into the 5v M4F chips from Cypress?
Such as the S6E2G36H0AGV20000
It shouldn't take much to move ChibbyOS over.

OS probably not too bad but also would need HAL (peripheral drivers)

Welcome!

Ya I did a little more searching and it looks like you looked into the FM4 series before.
But support was a bit limited.

I haven't touched any RTOS systems, so I'll need to learn a fair bit there. Those cypress dev boards are about $65CAN so I may grab one to play with.
But considering the work put into the STM32 already, it might be easier to just stick with that.
What about a 5v ADC?

Ps. It's late Thanksgiving evening here. So I've had a few.

What features are you looking for? It looks like this cypress chip is a fairly generic 32bit arm, with a fairly standard number of IO. I'm guessing that a chibiOS supported chip is possible, which satisfies your desired features. If chibiOS already has the HAL drivers, that greatly simplifies the effort.

We have put in some effort into the STM32F407IGT6 a 176 pin 32bit ARM.

Also there has been some looking into stm32f429 on the below board.

We have also considered SPC56## also known at MPC56## chips. These have 2 ETPU's which can do some low latency operations. The key problem is that the ETPU compilers are a pain. There are assembly compilers, but not free C compilers. As well there are some pre-compiled modules, but they typically are missing things you really want. So you either need to purchase a compiler, or write a bunch of code in assembly. However having 3X processors is a nice feature.

I believe some of the F7 discovery boards are also pin compatible with the F4 might be worth taking a look at those as they would be the easiest speed boost if someone was willing to put the time into making it all work.

I believe some of the nucleo boards carry F7 processors and are a bit newer in terms of ST link etc but would need to be pin compatible with the existing kit?
