I am using TIM3 of Stm32f407ve MCU.CPU is running at 168Mhz and clock to TIM3 is 84MhzNeed to select right values of PSC and ARR for accurate timing.is this correct assumption?Time_us = ( (psc+1)*(arr+1) ) / 84Mhz ??
I'm using TIM5CH3 to toggle an I/O, but AN4013 doesn't list a formula for the Output Compare, so I'm using the Timer Base Generator in Section 2.2: Update_event = TIM_CLK/((PSC + 1)*(ARR + 1)*(RCR + 1))With TIM5 CLK of 60Mhz, Prescaler 60-1, and ARR ...
I just bought a STM32G031K8 Nucleo, and when I connect it to ST-Link through Normal mode, the device is not recognized. It hangs, and ST Link throws the error shown in the picture. There should be a problem with Reset because it says it cannot rese...
I want to write a CAN Loopback mode program. But I don't know how to write it.Show me all the code of CAN Loopback mode program using STM32F4.
I am using code generated using CubeMX to configure the RTC, however the HAL_RTC_Init() function is returning an error. The clock configuration is this -void SystemClock_Config(void){ RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef R...
I am getting two bytes making 15 bit adc result via SPI bus. Is there a way to make SPI operation atomic, what aboiut DMA. And what about code in general, how does one disable interrupts or make thing atomic.Please note, there is no rush, the CPU is ...
Sorry. Forum structure / operation unfamiliar to me. I posted a question and got an answer.GOOD! I think. So I logged out. Did some work. Came back later. Logged in. I thought the question was in STM32 MCU's. If I type my user name in the search b...
Hello Team,I would like to change the Frequency of the clock in two different threads. I tried two ways.1./* Enable HSE Oscillator and activate PLL with HSE as source */RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;RCC_OscInitStruct.HSESt...
Hi All;I am working on an STM32F429I timer (PWM-mode1) to obtain two signals then I want to use AND gate inside the program (the input is the two signals come from timer Ch1 &Ch2) and designate one pin to be the final output.
HiI am making a project on a STM32F767ZI MCU and with this situation I cant efficiently test the code which depends on input/output of digital and analog variables because i dont have access to the hardware (in this case i want do drive a motor and i...
