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...
Hi I am using STM32L082, in my application I would like to calibrate the MCU once/twice per day. I would like to know whether clock re-initialization is required after adjusting the calibration value using "__HAL_RCC_MSI_CALIBRATIONVALUE_ADJUST(_MSIC...
Hi,I'm writing data to a 24 bit register of an AD5664 DAC from an STM32F429 discovery board which I am using to produce sinewaves and slower sawtooth ramps. The full loop lasts approximately 200000 bytes which gives sufficient resolution over all wav...
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.
