Hello,I have troubles using I2C with the STM32F103C8T6 "Blue Pill" board. I set up the code in CubeMX, using LL Libraries. After initializing the I2C periphery I try to send the address, but the ADDR bit in I2C1_SR1 register remains 0. AF bit remains...
I'm using the standard ANSI va_args approach here: int64_t arg64 = va_arg(args, int64_t);When stepping through the code the debugger clearly shows me a value like: 0xbeefbeef00000000

What would be an efficient, low latency way to reflect the state of an input pin onto an output pin?Is there anything more automated than configuring the input pin as an EXTI, then in the interrupt handler, reading it and setting the state of the out...
