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 https://starlinedubai.com
