Hello,
I'm working on a project in which I want to generate some trigger output ( which is connected to a sound chip APR33A3). Hence, I'm using the controller STM8S003FS GPIOs to generate the trigger output. Unfortunately, for an unknown reason, some of the GPIOs are not working properly in the normal push-pull out mode. I've marked them in the Image attached below. The output of these GPIOs is staying unchanged (checked physically via multi-meter).
I'm also adding the snippet of my code, so, if I made any mistake please let me know.
The nor working pins are as follows:
- PA3 (HS)/[SPI_NSS] TIM2_CH3
- PD3 (HS)/AIN4/TIM2_CH2/ADC_ETR
- PD4 (HS)/UART1_CK/TIM2_CH1/BEEP
