My application is executed from flash and external SDRAM.I have a bootloader(seperat project) that saves the volatile SDRAM content on a QSPI.Normaly my application is applyed by a .hex file that is located on the SD-Card. So my bootloader can clearl...
I am using STM32H753 MCU. I am using ADC1 and ADC2 and calibrated the ADC offset using auto calibration function. But this function is not working properly. I am getting a difference of 50 counts on subsequent starts of my device. I checked this by g...
Refer to https://www.st.com/resource/en/datasheet/stm32f446re.pdfIn section 3.23 on PDF page 32, it says:"The devices embed four universal synchronous/asynchronous receiver transmitters (USART1, USART2, USART3 and USART6) and four universal asynchron...
Howdythis line: hadc->Instance->CR |= ADC_CR_ADSTART;at the end of: HAL_ADC_Start_DMA(ADC_HandleTypeDef* hadc, uint32_t* pData, uint32_t Length);is causing a crash / reset. I've used HAL for this set up quite a few times with no problems, but this ti...
void delay_setup(void) { rcc_periph_clock_enable(RCC_TIM6); timer_set_prescaler(TIM6, rcc_apb1_frequency / 1000000 - 1); timer_set_period(TIM6, 0xffff); timer_one_shot_mode(TIM6); } void delay_us(uint32_t us) { TIM_ARR(TIM6) = us; TIM_EGR(TIM...
Hello,I'm working with a STM32F446 and I configured the SPI as slave.In my process I receive x bytes of data in interruption. But during the process, this size of data changes to y. But the function HAL_SPI_TransmitReceive_IT(x) has already been call...
I'm writing some code with PWM and I'm using very high number of periods in short time causing my LED's to dim very choppy. I think it's not working properly because timer is to fast and counting in milliseconds and I need it to count in microseconds...
Hi, I'm working with a STM32F446ZET6. In this case, I configured my SPI as slave, and I use the HAL_SPI_TransmitReceive function.The problem is that when the slave shoud respond with the value 0x11, I receive 0x22 on the master side.I have checked th...
I have a brand new P-NUCLEO-IHM002 out of box. I configured it according to the instruction. however, when power up, D11 on IHM07M1 is not light at all. when i push the blue button, no response. LD3 on Nucleo-F302R8 is on, LD1 is flashing. Can you he...
I would be more than willing to participate regardless of time, but due to health reasons I can't stay up all night. I really need the workshop to get up to speed on the STM32H7 for a project I am working on. Thanks!
