(stm32f4) GPIOx_BSRR vs GPIOx_ODR - Stack Overflow
WebDec 7, 2024 · I am trying to program my bluePill to blink an LED at the PB11 pin while echoing whats being send over the serial port UART1. as far as my knowledge, Interrupts allows us to run the programme we want and while running it if any flag triggered an interrupt signal the program the control will be diverted to run the interrupt service routine while … Web8. The BSRR has bitfields that allow you to set and clear bits in a port atomically--without a read-modify-write operation. Instead of reading the ODR value, ORing it with the bits to set, and writing it back, you simply perform a single 32-bit write to the BSRR to set or only the relevant bits. This often means you don't have to disable ... fort bragg nc bah 2023

Webtrying to read MISO line, but it returns 0xFFFF. first I send 0xC000 on . MOSI and the sensor places 0x0032 on MISO. I read MISO using oscilloscope, but in code, this value is 0xFFFF. I tried to send dummy data but nothing . changed. here is my code: Each GPIOpin has around sixteen alternative functions like SPI, I2C, UART, etc. So we can tell the STM32 to use our required functions. … See more Before looking into the control register, we will see the Clock Register (RCC_AHB1ENR) which will enable the AHB clock to the GPIO ports. See more This register is used to lock the configuration of the port bits. The below register is used to do that. 1.
