Hello, customer using custom F412 based board has a problem entering STM's System bootloader/DFU for FW upgrade (done over USB) when there is an active communication done on the CAN port. E.g. the board is part of the slave HW of the CANopen network ...
Good evening community members,today I have been trying to activate USART module of my STM32F446 board. However even after trying everything, I could not sense Tx signal on PA2 pin of the board. This is the low level code I used. I had been trying to...
HI,Is there any MCUs supporting PROFINET TSN?
Hallo,for security reason I have to stop HRTIM generating 3-phase signal for PMSM motor.It works as described in RM0433 (37.3.23) with DBG_HRTIM_STOP = 1: when debugger stops MCU predefined "FaultLevel" appears on outputs as expected. HRTIM goes into...
Hi,we develop a device using the STM32U545 MCU.This device will be accompanied by a desktop application (developed by us as well) which will enable our customers to interact with the device, e.g. to configure certain settings. It is a requirement tha...
Hello, I wanted to have SPI with DMA RX, below issues I face: 1. When SPI RX DMA function used with no TX DMA configured in MX (but blocking SPI TX used), It remains in RX busy state 2. When SPI RX DMA function used with blocking TX function, SPI wo...
I am trying to make a music visualizer with led matrix and stm32f411 usb audio functionpreviously , i tried to use stm32f103 blue pill but the usb audio stuck and i can't find the reasonso i purchased the black pill to do it but now the problem is th...
What is the difference between Oversampling Continued vs Resumed mode?I understand that in Oversampling Continued without resetting the accumulator in between individual samples for that channel. Resumed Mode resets it.I don't understand the implicat...
Hi,I'm trying to apply an Offset on the ADC, I'm using a H743. I'm pretty sure I have the ADC working correctly, because measuring temperatures (MCU internal and one external) as well as measuring some voltages on my board result in plausible values....
