Pinmode function in c

WebbThese functions work directly on the Raspberry Pi and also with external GPIO modules such as GPIO expanders and so on, although not all modules support all functions – e.g. the PiFace is pre-configured for its fixed inputs and outputs, and the Raspberry Pi has no on-board analog hardware. void pinMode (int pin, int mode) ; WebbUse configurePin in a MATLAB ® Function block with the Simulink ® Support Package for Arduino Hardware to generate code that can be deployed on Arduino Hardware. Configure the Arduino peripherals using configurePin before using it in the MATLAB Function block. The function does not return any output during code generation.
