STM32H743 BLDC use Hallsensor get speed(HAL)
LED1_TOGGLE();cant run when i start BLDC. can someone solve it? status of HAL_TIMEx_HallSensor_Start_DMA is OK and Mspinit is OK.void hall_init(void) { __HAL_RCC_DMA1_CLK_ENABLE(); __HAL_LINKDMA(&g_htimx_handle, hdma[TIM_DMA_ID_CC1], g_hall_d...
STM32H7: jumps in ADC transfer curve; both with Self-calibration, and FactoryLoad
Dear ST experts,we're currently struggling with getting acceptable ADC performance with some of our samples of the STM32H753VIT ADC2. Our setup includes:ADC2 works in Independent modeusing Scan Conversion Mode, 7 Channels (3, 5, 9, 10, 15, 18, 19)14-...
Can I configure a Timer in center-aligned mode to start counting from a value other than 0?
Hi everyone,I'm using an STM32 timer in center-aligned mode, and I would like the counter to start from a value other than zero. Specifically, I want the timer to count from a custom value (e.g., 2000), up to the auto-reload value (ARR), and then cou...
MIPI-DSI on STM32U5G9 - how to get started?
Today I tried to configure MIPI-DSI on STM32U5G9 using CubeMX and I did not win this first clash.MX_DSIHOST_DSI_Init() function fails executing HAL_DSI_Init() where it waits for DSI_PSR register flags PSS0, PSS1 and PSSC to be set (indicate both lane...
Resolved! Using Timer to trigger DMA event to write into GPIO->BSRR
Hello, I am currently pretty stumped over the behaviour of the DMA triggered by a timer.I want to use the DMA to toggle a GPIO pin using a timer for the right frequency. I am currently using the DMA driver from Zephyr. MY board is the STM32G071RB.I w...
Resolved! X-CUBE-CLASSB-U5(STL) issue(Hardfault) of TM7 test executing in ThreadX
Hello Support team,We are working on the Class-B on STM32U585 microcontroller-based product.We have added the ThreadX support in the X-CUBE-CLASSB-U5(STL) library example code. SW Configuration :- STL library runs the Secure region- STL APIs calling ...
Powering Nucleo-144 through E5V
Hi!I designed a shield for the Nucleo-144 (F429ZI) which provides power to the Nucleo-144 board through the E5V pin.To configure the board, I did the following:Place JP3 E5VRemove JP1Remove JP6Remove JP7Open SB169Close SB115I disconnected the ST Link...
STM32H743 ADC values fluctuating after voltage divider
I have a +30V -30V input to be fed to STM32H7 ADC 16-bitI tried using a 2 resistor potential divider using 33K 3.3K ; 1K 100E, 1M 100K, resistor combinations but the output is not correctly read by the ADC. (For 3V input, ADC reads from 2.2V to 3.2V ...
Resolved! CAN in Normal Mode with STM32F407 microcontroller
Hello everyone, I'm trying to switch from loopback mode to normal mode. So the program is working perfectly in loopback mode but i had to adapt it so i can use it in the desired normal mode. I switched to the HSE as a source clock for CAN communicati...
