New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

ADC input and GPIO output on the same pin

Does anybody have any experience in using exactly the same pin as an ADC input and a communication GPIO (out), as two alternating functions? Would it be possible to switch between them? If so,can the GPIO drive the small capacitor that is typically n...

BLUENRG_LP STEVAL-IDV011V1 issue

I can’t program my STEVAL using SWD neither UART right now. My last FW only configures my accelerometer an them goes to SHUTDOWN. When the MCU is on SHUTDOWN mode I could never program STEVAL using SWD (in Keil or using BlueNRG-X-Flasher Utility), bu...

Resolved! STM32L431RCI: Why is the voltage on pin VDDA jumping from 1.85V (external voltage regulator) to 1.94V after ADC_CR1_ADEN bit is set?

Source:int main(void){  HAL_Init();  RCC_OscInitTypeDef RCC_OscInitStruct = {0};  RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};  RCC_PeriphCLKInitTypeDef PeriphClkInit = {0};  /** Initializes the CPU, AHB and APB busses clocks   */  RCC_OscInitStruct.O...

Resolved! How can I set the address for DMA

I try to use DMA to transport data from GPIO input regester (GPIOx_IDR) to some other buffer memory. DMA reguest is created by timer with input capture mode so I turn on DMA by HAL_TIM_IC_Start_DMA(). This function doesn't have a arugument for source...

STM32L01x SPI Transmitt 32bit

Hello Guys,I'm new here and more from the hardware side.My problem is, I have a SPI ADC (ADS8665) and for it to work, it needs 32bit commands.So I tried this:uint8_t buff[4]; buff[0] = 0xC8; buff[1] = 0x00; buff[2] = 0x00; buff[3] = 0xC8; HAL_SPI_Tra...

I am using the STM MCU timer for PWM. This PWM signals goes as input to external MOSFET configured as push pull. So I want the timer pin to be in high impedance state during some instance of time and rest of the time give the PWM output signal.

I tried the following functions to make the timer pin high impedance, but nothing works:-          __HAL_TIM_DISABLE(&htim3);          TIM_CCxChannelCmd(&htim3, TIM_CHANNEL_3, TIM_CCx_DISABLE);          __HAL_TIM_MOE_DISABLE(&htim3);I also tried to c...

Resolved! I am trying to set up a I2C slave using a STM32F103C8Tx

I used STM32CubeIDE to create the project. The configuration that I used for the i2c is attached. I generated the code and added the following code in the "USER CODE BEGIN 2" section right after the call to MX_I2C_Init(). I made no other changes. uin...
