STM32 MCUs Products

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, ...

how CAN memory works?

Hello everyone i am using CAN bus to connect two stm32 boards, i would like to know does anyone of you know how does the CAN memory works? is it DMA or what exactly? i couldn't manage to find anyuthing on the internet and i really hope one of you can...

Data transfer between CAN bus and DMA on Hal stm32F4

hello everyone, i would like to know how can i transfer data from CAN Bus to DMA memory on stm32f4 board on HAL Library?  also i want to make sure that the CAN access memory is it DMA or somethign else?can you please explain to me how? or if you hav...

I would like to know To configure the I2C bus of STM32F439 in receive and transmit mode, which bit must be Set/Reset and in which register it is located, and how it is append to the Address byte...Thanks
