Differences between PWM channels 2, 3, 4 in TIM8?

I think I am missing something obvious about a difference between channels 2&3 vs channel 4 in the TIM8 after staring at this for some hours now...I am using the STM32H750 discovery board, and created a project in CubeMX which configures PI2, PB14 an...

Software download issue

Software download issueHi, I have met the same issue like this. Should I also wait an hour until this package been prepared?

DMA sets NDTR to 0xffff when enabled even when peripheral (SPI1 rx) is not enabled or has DMARX set. All memory is in D1 (AXI) and peripheral is working using interrupts.

Is it possible to use STMG070 USART break detection circuit in non-LIN (normal?) mode?

Hello,I would like to find out if it is possible to use STMG070 USART break detection circuit in non-LIN mode.Specifically, I have an application where I use a UART configured for high-speed data transfer (over a megabit) in DMA receive mode. Rather...

Can the SPI run at another voltage apart from VDD?

The data sheet isn't specific, apart from one diagram Figure 13 that shows IO's box with an arrow from VDD that then connects to a level shifter to the core domain.Please advise. A real handy feature would be to alternative voltage IO for the SPI's...

When setting up pins to communicate using SPI on a sensortile I changed the Pins so one is the C and one the B GPIO, how would I set this up, I haeve only seen one somewhat related thread that wasn't comparable, thanks!

GPIO_InitTypeDef GPIO_InitStruct; /* USER CODE BEGIN SPI2_MspInit 0 */ /* USER CODE END SPI2_MspInit 0 */  /* Enable Peripheral clock */  __HAL_RCC_SPI2_CLK_ENABLE();  __HAL_RCC_GPIOB_CLK_ENABLE();    /**SPI2 GPIO Configuration     PB15   ------> SPI...

Why my timer encoder mode oscillates in the same values?

Hi, i'm using my STM32F7 nucleo 144 and i'm learning about timer encoder mode and i follow the example in the datasheet but when i check the CNT register it oscillates in the same values and if i use the A0-A1 pins the encoder works bad, can somebody...

sd card sometimes corrupted when access it with sdmmc in STM32L452re

Hello everyone, I'm trying to build a sensor device that uses stm32l452re as MCU, I need to save my data to sd card using sdmmc features to access it. i using 4bit mode and clock divide 128, but unfortunately, my sd card sometimes corrupted and i nee...

Custom designed board not connectable - Reference Design Sensortile Used

I have a created a circuit from the Sensortile reference design and the MCU and the step down transformer both overheat, I am thinking the BGA pattern on the STM32 is off and there is a short drawing alot of current? BOOT0 is groundReset is pulled lo...

STM32L452RE ADC Bad value on just one of the 9 channels

I have STM32L452RET6P running at 1.8V, 24MHz. I am using nine ADC1 channels and am getting a very low value (about half) on ADC1-1 (PC0).All inputs are set up the same way, with an RC filter (33kOhm/0.1uF). The sampling rate cycle is 12.5 at 10bits, ...
