Does SimpleFOC work with botwheels?

From memory (3 years ago) I had a seriously complicated pullup setup. i.e. a pullup and a voltage divider.

On my halls (part of hoverboard motor), the hall needs 5V but the esc1 is a 3.3v and not 5V tolerant. therefore used a 1k pullup between h1 and 5v, h2 and 5v, h3 and 5v and then a voltage divider to step down 5v to 3.3v for each H1, H2, H3. So needed about 9 resistors. LOL

Sadly, I think that was a wasted effort
From my measurements between the hall pads and CPU’s VDD pin, ESC1 has 11.8K pullups onboard. And the hall sensors never output 5V, so there’s no danger of damaging the CPU. They do need 5V supply, but the output is either ground or floating, which is then pulled up to the 3.3V CPU voltage via the resistors.

All part of the exploratory process! :). It is not waste effort, esp when you tell others so they don’t have to check next time
