pinMode INPUT_PULLDOWN not working properly on MSP432

Recommended Posts

Here is the problem. In C:\energia-0101E0015\hardware\msp432\cores\msp432\wiring_digital.c the pull directions are ignored.



GPIO_PinConfig mode2gpioConfig(uint8_t pin, uint8_t mode)
   switch (mode) {
        case INPUT:
        case INPUT_PULLUP:
            digital_pin_to_pin_function[pin] = PIN_FUNC_DIGITAL_INPUT;
            return (GPIO_CFG_IN_PU);

        case INPUT_PULLDOWN:
            digital_pin_to_pin_function[pin] = PIN_FUNC_DIGITAL_INPUT;
            return (GPIO_CFG_IN_PD);

        case OUTPUT:
            digital_pin_to_pin_function[pin] = PIN_FUNC_DIGITAL_OUTPUT;
            return (GPIO_CFG_OUT_STR_HIGH);
