Hi! I'm in a conundrum, and am wondering if there are hacks around this. I'd like to use CAN on a a G4. And give it updatable firmware by USB. My options appear to be this:#1: Share a CAN Rx line with Boot 0 pin.#2 Share CAN Rx line with USP_DN.Are e...

I have been troubleshooting a I2C device for longer than I'd like to admit. Today I attempted to configure with CUBE, and I think I've found the pin I'm using may not be compatible.PA10. Can it be used for SDA2? I thought it could based on the AF tab...

I'd like to use a ST VL53L1 to measure distance, but am thoroughly confused by the API. It uses a standard I2C protocol per the datasheet.In lieu of instructions on how to configure and take readings, the datasheet points to a separate document: UM21...

I'm looking for advice on connecting 25 PDM microphones to an STM32H7. This seems possible from the RM, taking advantage of 4x SAI peripherals, each supporting up to 8 mics. However, when checking avail User Manual pins on several H7 variants, they ...

Hi. I'm having trouble with integer interpretation for DFSDM. From the RM:> The offset correction allows to calibrate the external sigma-delta modulator offset error. The user configures the offset register with a signed 24-bit correction, and this r...

Just got bitten by this; request User Manual update please.

Related piece of the puzzle: I think PA8 may be the intended (and implemented in hardware) SDA2 pin. It shows as SMBA on the second DS table. I'm not lion!

I appreciate the effort there! I'm hand-translating it; almost done. I figured the auto translater would have trouble with accessing the I2C peripheral at least. I'm trying to use a type alias for the int returns; if that doesn't compile, I'll just ...

Thank you for the detailed information. I'll order an eval board, and have a go at porting the ULD library. I skimmed it, and it seems quite approachable!The fact I'm using an Stm32 for the MCU is a coincidence, but it can't hurt here!

Thank you very much - that answers my question, and the design decisions (Many regs, lots of ways to configure, and an official software API) makes sense in context. I'll dive into that library, either to use as a reference, or use FFI (Or the C2Rust...
