The ST60A3H1 looks very interesting. While I understand an NDA is required for access to the complete details on this solution, would it be possible to say if it works underwater as communication between ROV modules?Scenario:IC A | 1mm air or mineral...

I'm finalizing the design of a BLDC motor controller (up to 48V / 40A) and I'd like it to work well with HSO and (when available) ZeST.From other forum posts I've found the need for phase voltage measuring and to be able to capture these simultaneous...

I have an STM32G473 and would like to use DMA to send a circular buffer to a set of 8 GPIOs, 6 using port A, 2 using port B. Two uint32_t arrays of equal length work as circular buffer, to be fed in the respective A or B BSRR register. Timer 7 (can p...

Are there any guides or tips on making an STM32 MCU last in a high temperature (~150°C) environment? Specific voltage or clock speed tweaks?The MCU would sleep most of the time, but now and then take and store some measurements.Would certain families...

tldr; Can I have a timer counter reset (once / one-shot) when the RX pin of a CAN-FD peripheral is activated, so I can later determine the exact time elapsed?I have a chain of ~8 STM32 devices on a ~2m CAN-FD bus. Several MCU part numbers (mostly G4)...

Thank you for the clear answers!

I have a BLDC controller / ESC design based on the STM32G473CEU, using in-phase shunts (and an external 50x bi-directional OPAMP). How can I make this design compatible with ZeST and HSO?Currently the ADCs are used as following:ADC1: VM / bus voltage...

This bug is still present, I just hit it.Enabling I2C1 and I2C2, only I2C2 will show up in CubeMX's 'Generated Function Calls' list. But then set I2C1 to SMBus it shows up. Set it back to I2C and the entry in the list remains.CubeMX 6.9.1 with G4 pac...

After Imen's reply I indeed went Googling to see if I could find a similar document on the F4. Now you mention it, the mixed signal F3's might be interesting indeed. We'll indeed be testing, but first it's key to understand what to test and have some...

Thanks for your insights so far, Pavel & JW.The STM8 would be interesting, but don't fit the performance needs. A G4 at 26MHz would probably be the minimum. CPU active times at this performance level would be very short, far less than a second.The en...
