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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello all,I'm having some serious problems communicating with a device attached to USART2 on a custom STM32L496RGT, board, configured in CubeMX.void MX_USART2_UART_Init(void) { huart2.Instance = USART2; huart2.Init.BaudRate = 115200; huart2.I...
Hi all,I wanted to make use of LPTIM1 module of STM32H723ZG for generating 1ms interrupt.Clock frequency used 64Mhz (HSI).Environment: Nucleo 144 STM32H723ZGPrescaler: Divide by 128Auto reload register value: 500uBelow is the code snippet of init fun...
I am using the STM32L4S9AII6 clocked at 120MHz.I am trying to configure a simple (to me it should be simple) retriggerable one pulse mode timer. I was able to configure TIM6 in one-shot mode, but I had the following issues:The timer was not retrigger...

hey thereI have a STM32f030C8t6 which I wish to read 2 Analog values by it. I use ADC DMA for this. but as soon as I use commandHAL_ADC_Start_DMA(&hadc,(uint32_t *)ADC_SEN,2); //Starting ADC1I can see my ADC pins' volt are as high as 3.5volts!why is...
Hello,I would like to make timer 2 compare event in channel 1 to clock timer 5. Timer 2 compare events also sends DMA request and timer 5 is also used to output a PWM waveform. Here you can find the Init function that I wrote and the main code. At th...
We are developing a custom board with STM32G030 and we intend to update its program through its uart with system bootloader. However, I'm unable to properly configure the option byte. The HAL_FLASHEx_OBProgram always returns HAL_ERROR or HAL_TIMEOUT....
Hello. I have been getting familiar with the STM32L011F4P6 chip. I am using a 20-pin chip soldered onto a board as my test device. I am using a Nucleo-f429zi as the programming/debug device. I have made the necessary changes and am using the SWD head...
Hello everyone. I have a stm32f411 discovery board. Long time ago it worked fine. But now when I connect the external led with GND and 3V pin, the led is not on (the led is ok, I already test it with an arduino board). I don’t know why. Other functio...
