Tiqdr It s true that number of external GPIO interrupts are limited to 16 and you can t configure PA0 and PB0 as source at the same time However external interrupts are not the only way to read
On page 31 of datasheet it says that PA0 has many alternative functions TIM2 CH1 ETR USART2 CTS WKUP ADC123 IN0 TIM5 CH1 TIM8 ETR From the reference manual I know I have a stm32f103c8t6 which I wish to turn PA0 from ADC mode to GPIO after reading ADC value in order to let the pin to discharge completely and then back to ADC mode for the next

I am trying to configure the STM32F411CEU6 onboard button PA0 but cannot configure it to use the internal pull down resistor My current setup allows it to trigger an interrupt That means that you cannot connect both PA0 and PB0 to EXTI0 In fact there are four specific bits in the alternate function input output register AFIO which let you choose which pin is
0 Can I share the pin PA0 between timers TIM2 TIM5 GPTIMs Timers 2 and 5 can both use PA0 as an input conveniently on ch1 Is there any issue with configuring both of them to Periodically using the RTC wakeup timer By pressing a push button connected to the PA0 WKUP pin Depending on whether the application was woken up by the RTC or the push

I am developing a board where 40 low I O ports will be read and I would like when I detect a low border to activate interruption for reading the port in the documentation it says that Up to 168 I am not sure if this forum is right place to post such questions but me as a beginner in STM32 facing the following problem I have connected LED to PA0 pin in nucleo STM32L073RZ
