I just got a simple program running on my STM32f0301k6. I am running the clock off a 20MHz crystal and the core is running off the PLL x 2 so everything is running at 40MHz. This means one cycle executes in 25nS, but if I write a loop like GPIOB->...
Hi,I have configured DMA and SAI interface as below.void HAL_SAI_MspInit(SAI_HandleTypeDef* hsai){ GPIO_InitTypeDef GPIO_InitStruct;/* SAI2 */ if(hsai->Instance==SAI2_Block_A) { /* Peripheral clock enable */ if (SAI2_client == 0) { __HAL_RCC_...
I've got an application where the main() function needs to be non-standard. In older version of GCC this wasn't an issue but the newer versions seem to have changed somethingI need:void main(long long int *c, long long int *b)but GCC is overriding th...
Hello Team,i have flashed B-L475E-IOT01A-WiFi-Bridge-S2LP binary into the B-L475E-IOT01A board and then it asked to enter the input ssid , password and security type. i given all correct value but we are getting the response like "Given SSID not F...
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 ...
