Here is my process :I supply my board with an USB cable.Then I flash my stm32L4 with a segger / st-link.My firmware goes in shutdown mode.I unplug the USB cable. Thus the power is suddently off.After that, I wire a battery to my device. Thus the MCU ...
Hi, i am new to stm32 i need to write negative values (signed integers or float) in my modbus and transmit it to my PC. But i am not able to write negative values it shows some other values if i transmit negative values . can anyone help me w...
Dear ST,I am coming back to you to configure a PWM peripheral with STM32F429.I am familiar with TI DSP and I have to implement it with ST this time.Could you help me to configure TIMER1 for symmetrical PWM and trigger an interrupt to trig ADC. I ma u...
Posted on March 20, 2012 at 06:20Hi. Could You help me to understand somethink. In STM32 like STM32F103c8... there is a clock signal called RCC_APB2Periph_AFIO. When should be turned on this signal, always when I use peripherial, like Timmer, AD, US...
Hi Folks,Greetings !With a Nucleo-G474RE MB1367C, with an onboard 32.768kHz crystal:I am trying to turn ON the LSE oscillator, but the LSE oscillator does not get RDY at all.This is what I tried to do:void SystemClock_Config(void) { LL_FLASH_SetLate...
Hi team,We are increasing the Input voltage 0.5 Volts/ Minute to Input of PMIC. PMI switches on after the Input voltage reaches 3.7 volts.After PMIC switches on it gives 3.3Volt Output but Controller is not getting reset.If we Power up instantly cont...
Hello,When I use DMA with SPI it is not working.When I get a falling edge on DRDY this function gets called :void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { if(GPIO_Pin == DRDY_ADC_Pin) { HAL_SPI_Receive_DMA(&hspi1, SPI1_RxBuffer, READBACK_LENGT...
I'm developing a project with a lot of peripherals running at once. I wanted to add a rotary encoder on Timer 3 but it refused to do anything at all. The TIM3->CNT Register just sits at 0. Otherwise one PWM Channel of Timer 21 as well as the RTC are ...
I need what max size sd card i can connect to DIscovery Board containing Stm32f07d Controller over SPI?As am planning to take that reference in my design.And what is the solution to interface sd card of 8GB Size over SPI in Stm32f072 Controller?Also ...
