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...
