Hello everyone,I'm working on a custom board with an STM32H563 and using CubeMX, HAL, and ThreadX.I am trying to receive variable-length UART data via DMA using HAL_UARTEx_ReceiveToIdle_DMA(). My problem is that the HAL_UARTEx_RxEventCallback never t...
I have several an 2 F401RE boards connected to my PCs and getting data by the Virtual Communication Port.Unfortunately when installing a new board on the PC, I ve seen that my 2 boards were declared by Windows with the COM portCOM port 7, 9 and 10 ar...
Hello folks,I am investigating the Video Encoder on the STM32N6 and have been working through the reference project (VENC_SDCard_ThreadX).The user manual (RM0486) is very vague on detailing the Video Encoder, and lists over 100 pages of registers whi...
Hello,I'm here on H75x. I'm looking for portable way to do a timeout check via timer.Here, I want a timeout IRQ if UART receive DMA hangs up.First I setup a OnePulse timer in Cube. It generates the following code:if (HAL_TIM_Base_Init(&htim6) != HAL_...
Hi,I’m using an STM32L052 with LQFP32 package, VDD = 1,8V.According to the datasheet:“VDD_USB = 1.65 to 3.6V: external power supply for USB transceiver, USB_DM (PA11) and USB_DP (PA12). To guarantee a correct voltage level for USB communication VDD_U...
Hi, I am using a STM32F411CEU6. I am trying to make the One Pulse Mode of TIM1 start every time TIM2 has counted its ARR. However, I don't seem to really understand what the relevancy of the ARR of TIM1 is when having TIM2 controlling the start(exce...
Now I've been sitting here for 2 long day's and still haven't been able to solve the BUS-error problem. I'm logging with Kvaser USB CAN card so what I want to see right now is some healthy frames coming out from it, but no, only bus-errors, so I thou...
Hello, I want to use LTDC on the STM32H743VIT6 microcontroller, but when I enable this peripheral in CUBEMX, it does not activate correctly. For example, the pins for B are from B3-B7, while they should be from B0-B4, and the same goes for R, G.
Hello, I bought STM32H743XIH6 board and first tried to program it with FTDI programmer and STM32CubeProgrammer. It looks like the serial interface detects the board correctly as I can see it in the STM32CubeProgrammer but fails at a read attempt of 0...
Hello,I’m developing a USB composite device on STM32 that combines RNDIS and CDC interfaces.The device works perfectly the first time it’s connected to a Windows 10 PC — both RNDIS and CDC functions operate normally.However, after I reset the MCU or ...
