I was doing reset through SPI command and expected results are not happening. this is the line i was expecting to reset the MCUSCB->AIRCR = (NVIC_AIRCR_VECTKEY | (SCB->AIRCR & (0x700)) | (1 << NVIC_SYSRESETREQ));where#define NVIC_AIRCR_VECTKEY (0x05F...
I am using the STM32H725RE (68-pin package).My goal is to have full duplex SPI communication with a 16 bit shift register using the stm32h7 as the SPI master (with no dma controller).I am using the SPI3 with the following pin (12MHz)PA15 (SPI3_nCS), ...
I am trying to flash a .bin file to an STM32F767ZI Nucleo board using UART via STM32CubeProgrammer. While I can successfully connect to the board using ST-LINK, I am unable to establish a connection over UART and encounter the following error: I ha...
Hello, Developing a firmware to update the application via Bootloader over USART2. But, the STM32U5G9BJYXQ is not responding on 0x7F. The MCU is successfully starts from the NSBOOTADD1(0x0bf90000) on driving the BOOT0 pin high while deasserting th...
I am trying to source a 12.288MHz clock for an STM32L433 but having difficulties finding something.The clock is required for I2S playback with a bluetooth receiver (BT401).I have tried using the internal MSI RC to generate the 12.288MHz clock for SA...
helloDescription:I'm currently working with the STM32U585 and encountered an issue related to GPIO behavior after waking up from standby mode.Before entering standby, I configure certain GPIO pull-up:(No external pull-down resistors on the affected p...
I have seen the question asked many times, references made but the question never gets answered with precision. So, once again...I want to use HAL_I2C_Master_Seq_Transmit_IT along with receive to read an I2C device register.1. START SLAVEADDRESSWR (...
This PCB is used to control a 24 V DC motor and is powered from a DC power supply. The STM32F0 microcontroller resets continuously, and the NRST pin voltage fluctuates and then remains at a low level, even when the motor and power stage are completel...
Hello,We are currently using the STM32G070CBT6 microcontroller in one of our data logger devices, which operates on a three-phase power supply and is used in a transformer application. In our design, the microcontroller triggers a relay, and the rela...
Using the information from the chip's datasheet and reference manual:I have the following routine (using the HAL routines). My issue is that I have verified code execution and setting of the two OB values via JTAG, but when the system reset is issue...
