For instance, toggle a pin between high and low states in a simple loop to check if the issue is with the GPIO or the rest of the system.
Example: c while(1) { GPIO_Write(GPIOA, GPIO_PIN_0, 1); // Set PA0 high Delay(1000); GPIO_Write(GPIOA, GPIO_PIN_0, 0); // Set PA0 low Delay(1000); }
7. Check for Firmware Bugs:
Review the code thoroughly, especially the GPIO setup code. Ensure that there are no logical errors such as overwriting configuration registers or incorrectly handling pin states.8. Resolve Peripheral Conflicts:
If the GPIO pins are also used by other peripherals, disable or reassign peripherals that may be conflicting with GPIO functionality.Additional Tips:
Always refer to the STM8S003F3P6 datasheet and reference manual for the most accurate pin configuration and electrical requirements. If you are using interrupts on the GPIO pins, check that the interrupt configuration is correctly done. Use a debugger to step through your code to ensure that the GPIO pins are being initialized and used properly.By following these steps methodically, you should be able to identify the root cause of why the GPIO pins are not responding correctly and fix the issue.
