Hello,I've taken the code from the Timer cookbook example TIM_ExtCLK_ETR and modified it slightly for my purposes. I removed the DMA transfer and am looking directly at the TIM2->CNT variable at a 1 second interval for right now. In this case, I'm...

I have STM32L496QG soldered on my PCB. I can use only Boot Loader via Serial COM port. I tried to use ST's Flash Loader Demonstrator, it doesn't work. I need some Windows -based software. What can you recommend?
Hallo everybody,i would like to generate analog signal (0-5 V) via DAC but the problem is the maximam voltage is 3.3 V . ist it possible to change some configuration to generate an analog signal with maximam voltage from 5 V? thanks #DAC #[Analog an...
I do not know if and what I am doing wrong. I am using CubeMX and a Nucleo 64-Board. This is the while inside the main:while (1) { if(HAL_ADC_PollForConversion(&hadc, 1000) == HAL_OK){ adc_value[i] = HAL_ADC_GetValue(&hadc); media += ((f...
Hello,setting up STM32L412 SPI for 16 bit Spi transfer and doing: uint16_t *SPI_DR = (uint16_t*)&SPI1->DR; *SPI_DR = 0;// while (~SPI1->SR & SPI_SR_TXE) {NutSleep(0);} *SPI_DR = 0;results in only 16 bit shifted out. With the check for TXE e...
We have used STM32F429IIT6U in our project . In the beginning , it works fine but after few mins it get stopped. I have replaced the external caps, crystal and controller and also isolated the nearby controller circuit but it is still creating the s...
Hi there! I am actually fighting again i2c communication on the B-L072Z-LRWAN1 evaluation board (STM32L072CZ). Basically I would like to interface a NXP MMA8652 accelerometer over the I2C bus. I was able to do that (get the "who am I" register, get x...
i want to control AC voltage using timer PWM mode ..reference zero crossing signal interrupt every rising edge of zero crossingfrequency of pwm signal (100Hz) some time frequency of AC mains very between 99-100Hz so i need to synchronize my timer ...
