PWM valves (generally 2 wire) accept a variable duty-cycle square wave to control their position. Any general-purpose output hardware that can handle the electrical load can be configured to control a PWM-style idle valve. Dedicated pins do not need to be allocated for these style valves. Honda, Nissan, Mitsubishi, Subaru, Ford valves are commonly this type.
Bipolar stepper motors (generally 4 wire) have two coils that are energized in different patterns in order to move the valve open or closed, one step at a time. Bipolar stepper motors require **two H-Bridges** (Proteus) to control one bipolar stepper idle valve. Alternatively, a dedicated stepper driver IC can be used(Prometheus?) or added via a drop-in adapter board. GM, Toyota commonly use these.

## What about adding IGBTs on the board to drive coils directly?
Actually we already have this in the form of the Prometheus and Hellen boards.

These boards are intended as all in one solutions.

What-rusEFI-Cannot-Do.md
View File

@ -17,4 +17,4 @@ We get a lot of questions along the lines of "Can rusEFI run on XYZ processor?"
There are many possible STM32 chips and development boards available on Ebay and Aliexpress that might in theory work with rusEFI.
In reality there is absolutely no guarantee that any one of these will work as there are so many small variations of pinout, ram spec, processor speed, IO configurations, etc that it is impossible to support them all.
This is without considering the problems that come with fake/poor quality chips or the GD32 series.
For these reasons rusEFI only officially supports the chips listed [here](stm32-readme) we cannot provide assistance to get rusEFI working on any other chip set.
