Wiper (one-bit) STM32 Nucleo WB55RG I/O mappings

All signals are active high. The direction shown is relative to the STM32.

Runtime signal Meaning Type GPIO STM32 HAL name
rainSensor Rain is active STM32 input PC_13 GPIOC, GPIO_PIN_13
rightSensor Wiper is at the right-hand limit (minimum angle) STM32 input PA_6 GPIOA, GPIO_PIN_6
leftSensor Wiper is at the left-hand limit (maximum angle) STM32 input PB_9 GPIOB, GPIO_PIN_9
mButton The interface's M button is being pressed STM32 input PB_8 GPIOB, GPIO_PIN_8
pButton The interface's P button is being pressed STM32 input PC_12 GPIOC, GPIO_PIN_12
move Enable wiper movement STM32 output PC_4 GPIOC, GPIO_PIN_4

When move is high, the simulation moves the wiper and reverses its direction automatically at each endpoint. When move is low, it stops at its current position. Between the endpoints, both endpoint sensors can be low. The simulation's error control deliberately makes both endpoint sensors high so that controller error handling can be tested.
