I got almost all of my wishes granted with RP2350

This is very exciting! For the last several years I have been developing a brushless motor driver based on the RP2040 [1]. The driver module can handle up to 53 volts at 30A continuous, 50A peak. I broke the driver out to a separate module recently which is helpful for our farm robot and is also important for driver testing as we improve the design. However this rev seems pretty solid, so I might build a single board low cost integrated single motor driver with the RP2350 soon! With the RP2040 the loop rate was 8khz which is totally fine for big farm robot drive motors, but some high performance drivers with floating point do 50khz loop rate.

My board runs SimpleFOC, and people on the forum have been talking about building a flagship design, but they need support for sensorless control as well as floating point, so if I use the new larger pinout variant of the RP2350 with 8 ADC pins, we can measure three current signals and three bridge voltages to make a nice sensorless driver! It will be a few months before I can have a design ready, but follow the git repo or my twitter profile [2] if you would like to stay up to date!

That peaked my interest, here's the video for those who want to save a few clicks: https://www.youtube.com/watch?v=fFhTPHlPAAk

I absolutely love that they use bike parts for the feet and wheels.

* piqued

yes, piqued. English, so weird! ;-)

(Although, interest peaking is possible!)

> English, so weird

Borrowed from just-as-weird French "piquer" - to stab or jab.

It is kind of funny that both of the incorrect versions, peaked or peeked, sort of make more sense just based on the definitions of the individual words. “Peaked my interest” in particular could be interpreted as “reached the top of my interest.”

Way better than stabbing my interest, in a French fashion or otherwise.
