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

STM32Cube SPI interrupt example project does not work on STM32H743 ?

In order to investigate the SPI issues on my own setup (based on STM32H743 Nucleos) I gave a try to the SPI example project in STM32Cube 1.4 (SPI_FullDuplex_ComIT). Compiled and debugged with Keil 5.28.In this example project Slave and Master exchang...

Where can I find typical DNL and INL error profiles (X axes would be Vin and Y axes the error in LSB) for STM32L0 12 bits ADC, ideally with and without HW oversampling.

SDRAM configuration for 216MHz sysclk.

Hello, with a STM32F7508-DK board, all examples using SDRAM have the sysclk to 200MHz, therefore the FMC clock to 100MHz.I am trying to enable sysclk = 216MHz, and FMC = 108MHz, so I followed the SDRAM user manual, and configured the following settin...
