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...
Hi @Issamos Am planning to Quad SPI, which port we can use, i cannot able to find the data sheet below listed pins can use Controller -STM32U575VIT6 (LQFP64, 10 × 10 mm)QSPI_CLK → PB2QSPI_NCS → PB6QSPI_IO0 → PD11QSPI_IO1 → PD12QSPI_IO2 → PE2QSPI_IO...
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 ...
I'm designing a circuit to convert sensor values to ADC using the STM32U073MC (LQFP-80).Unfortunately, I'm new to the STM32U0 series.I read the RM0503(Rev 4) Reference manual(page 427) and found that the OPAMP1_VOUT can be connected to ADC1_IN8.How...
Hello, I am fighting about a week to enable USB-PD comms on my STM32G0B1 MCU and even chat GPT literally told me - he don't have a solution ( shock, a?) One last try before I quit, is to try 1.5.0 package version but I can see in cube MX only 1.6.0 ...
