STM32 MCUs Products

Hi everyone , i'm trying to connect my STM32f429I-DISC1 to LAN (getting an IP) using ENC28J60 , but i didn't found the correct library of this module . Can anyone help me please ?

STM32L071, LSE crystal and Driver Level

Dear,On MCU STM32L071 we use LSE crystal (32,768 khz) with param:Cload = 12.5 pFCshunt = 1.2 pFESR = 50-70 kohmDrivel Level = 1uWand I am not sure how to set up LSEDRV bits in RCC register. I computed (according to AN2867) Gmcritical=2.06 uA/VDo I un...

HAL_SPI_TxCpltCallback(SPI_HandleTypeDef *hspi) is not working!

I'm trying to set up a basic SPI interface using the HAL provided by ST on the STM32H750VBT mcu. What I am currently trying to do is to write anything to the SPI bus and while trying this i am using HAL_SPI_TxCpltCallback(SPI_HandleTypeDef *hspi)  fu...

what will be the problems of using Single VDD Pin (48PIN) connect to VDD voltage by keeping other VDD pins open ?

I'm using STM32f030C8T6 controller 48pin package ,i want to know what are the difference between digital power supply pin and complementary power supply pin . and also need to know that can i use only Digital power supply to VDD voltage for running t...

Emulated UART - Timer triggered DMA for reading GPIOB->IDR in STM32L433RBT6

Hello,I am using STM32L433RBT6 for receiving data from NEO6M GPS module. The requirement to add the module was given after the circuit board was delivered. Hence, I need to implement the UART reception using emulated uart (bitbanging technique). I ha...

I2C help please.

Hi everyoneI have a STM32F401RE Board and I am trying to get the I2C to work with an MPU6050. I have seen some examples but since I can not seem to find PB11 I realized I have to use PB3 as I2C2_SDA pin and PB10 as I2C2_SCL pin. The clock on this is ...

Differential ADC to measure voltages above VDD ?

When using differential ADC, it is safe to to measure voltages above VDD ?I am trying to measure a voltage different across a current sense resistor from 12VDC power supply.
