stm32f4 family gpio boundary address

helloi'm having a question. why gpioX boundary address(range) is 1kb ???according to datasheet, GPIOA's boundary address is 0x4002 0000 - 0x4002 03FF.but offset for register to be set is 0x00 - 0x24. i think that using 1kb to cover that range is inef...

Resolved! Timer1 doesnt generate an Output while Timer3 does (STM32L552)

I am trying to use the output compare mode of TIMER1 to produce an accurate time course on the PE9 pin. For some reason I don't get an output signal on this pin. Instead, when I use TIMER3 with the same settings as TIMER1, I get an output signal on p...
