Can the ODESC V4.2 board work with SimpleFOC?
Currently, I’m facing an issue with reading the current from the motor because the pins used for current sensing are:
// M0
#define M0\_IA PC0 // Not available as analog!
#define M0\_IB PC1
#define M0\_IC \_NC
```auto
Also, does it support current sensing via DMA?
Thank you!
```

Have you checked this discussion?

> Hello, I bought an ODESC 4.2 card (24volt) with STM32F405RGT6, a Chinese card that runs under Odrive3.6. [https://fr.aliexpress.com/item/1005005725467528.html](https://fr.aliexpress.com/item/1005005725467528.html) I got it to work with SimpleFOC slight_smile It works perfectly if I drive it with STMViewer and a “St-Link V2”. The motor is a skateboard motor in 24v 150w and 10 poles with Hall effect sensor. I can’t get a continuous potentiometer reading to work properly. I first tried adding analogRead() from GPIO =…

And about dma you already asked it here
