STM32U585 need help with getting ADC -> DMA working in trivial case.
This is what I am doing and want to accomplish: I am using ADC4 to convert internal temperature sensor in 1 second intervals, and move the converted value from ADC_DR register to a fixed address in RAM (no increment). At the end, I want to be able...
Resolved! Random generator
Hi I am using STM32G030K8. as there is no TRNG options I am doing the ADC noise values to generate a 8 bit number.The MCU is supplied with 2.2V supply .I am using both mains and battery for my operation.However if battery is removed Im not gett...
Issues with STM32H753VIT6 After Clock Changes - Not Responding or Reprogramming
Moved from the MPUs forum - H7 is an MCU, not MPUI am a complete beginner with STM32, and I'm currently working on a project where I need to transmit a simple 16-bit ADC value to USB using my STM32H753VIT6. I'm trying to figure out things myself, but...
low power with STM32U5 and LPUART
I'm trying to port code from STM32L4 to STM32U5.The STM32L4 code was using the LPUART, with a baudrate of 20k, clocked with HSI but in stop2 mode the HSI was stopped, it was able to wakeup and read incoming data. This configuration was using ~10uA.I'...
interfacing RMII and configuring its clock
I'm trying to get the ethernet initialization work. I am currently dealing with MX_ETH_Init(); failing in error handler as the software reset is not happening with the phy driver. I believe my clocks are not configured properly as per manual : As ...
CAN receive interrupt is transmitting received packet on Tx line automatically
Hi,I've been implementing CAN1 on NUCLEO-412ZG board. CAN bus is able to transmit and receive CAN packets. However, the problem is when board receives CAN packet from PC over CanAnalyser tool, it transmits the same packet on Tx line automatically. As...

DFU with custom VID / PID
Hi,We would like to use the standard USB DFU supplied with a STM32H747IGT6 with our own Vendor ID (VID) and Product ID (PID) instead of the default STM VID and PID. We are entering USB DFU mode by pulling the boot mode pin hi. We can run the DFU thro...
