I am using the STM32G474 and have the following situation:I have configured a Timer to run continuously at 25 kHzThe Timer triggers the ADC to start a sequence of 6 conversions (i.e. 6 ADC channels)Upon completion of each ADC conversion, DMA transfer...

I'm using the STM32WB55, with STM32CubeWB V1.14.1 & `stm32wb5x_BLE_Stack_full_fw.bin` V1.14.1.Looking in `app_debug.c`, I can configure `aGpioConfigList[]` and `aRfConfigList[]`, which allows for CPU2 to toggle a GPIO pin based on various events.I ca...

I'm am looking to prototype an RFID system that involves communicating with a 'smart' passive TAG at a range of about 40cm. Which evaluation boards (reader and passive tag board) would be best suited for this application?I'm am looking to prototype a...

Thanks JW, this is exactly the kind of answer I was looking for :party_popper:I don't think the proposed solution is entirely possible (only 1 DMA channel can be used per ADC on the STM32G4), however your idea helped trigger a similar solution that m...

For anyone else who stumbles across this in future:If you are using the Simple HAL functions, you need to call `HAL_HRTIM_SoftwareUpdate()` after you call `__HAL_HRTIM_SETCOMPARE()`.For example:// start the HRTIM PWM output HAL_HRTIM_SimplePWMStart(&...
