I am trying to retrieve data from the onboard ST MEMS gyroscope, but while setting up I2C I have been running into issues. At first I consulted the gyroscope data sheet to find the address associated with it, but both values (0x68 and 0x69) shifted t...
I have tried the HAL without success - It seems to hard fault when initializing RTC.I have privilege disabled, and trust zone disabled,Unable to access any RTC or TAMP registers.Here is a minimal example of code, including the snippets of misc things...
Hi friends, I have STM32L053C8T6TR, where I use PPS pulse from GPS connected to PB8. I set this pin: #define GPS_PPS_Pin LL_GPIO_PIN_8 #define GPS_PPS_GPIO_Port GPIOB void gps_pps_pin_init(void) { LL_EXTI_InitTypeDef EXTI_InitStru...
My connection is below:I have configured STM32F407G as master and STM32F429I as slave from CUBEMX. According to reference manual "The idle state of SCK must correspond to the polarity selected in the SPI_CR1 register (by pulling up SCK if CPOL=1 or p...
Hi.In PM0214 programming manual page 40 it says:On system reset, the vector table is fixed at address 0x00000000. Privileged software can write to the VTOR to relocate the vector table start address to a different memory location, in the range 0x0000...
I'm using a nucleo F446RE. I want to set up MCO1 as 42MHz output. CUBEmx generated the the HAL_RCC_MCOConfig function below.void HAL_RCC_MCOConfig(uint32_t RCC_MCOx, uint32_t RCC_MCOSource, uint32_t RCC_MCODiv) { GPIO_InitTypeDef GPIO_InitStruct; ...
Hi there,Here is the code for DAC with DMA. I can not see the error in the code. I have been looking at the oscilloscope for the sine wave but it is not coming. I tried without DMA, and works nice. But the DAC with DMA is not working. Please someone...
Hello!Currently i am working with the STM32h745 dual core MCU, i am tring to create somekind of synchonization between the m4 and the m7 cores.for that i want to utilize the SEV. i already enabled the proper iterrupts in both cores.my question is how...
Hi there,Here are the two lines which I am using for SPI communication.while(HAL_SPI_GetState(&hspi3) != HAL_SPI_STATE_READY); HAL_SPI_TransmitReceive(&hspi3, (uint8_t *)& ADC_write, (uint8_t *)&ADC_read, 4, 100);The drier derived from CubeMX is not...
