The APBCLK/AHBCLK is 80MHz. when I toggle the GPIO in the callback, the scope trace gives me interrupt generation of 2.3 usec instead of 1usec. Is there any timing limitation for interrupt generation?
Hi, I'm trying to calibrate the ADC3 on my STM32F303RE microcontroller. In according to the REF MANUAL, I enabled the ADC voltage regulator and then started the calibration but code get stuck in the while loop forever (ADCAL is always 1). I put the f...
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....
