32 * @brief C++ API to Analog IO
34 * This file defines the aio C++ interface for libmraa
36 * @snippet examples/c++/AioA0.cpp Interesting
41 * Aio Constructor, takes a pin number which will map directly to the
44 * @param pin channel number to read ADC inputs
46 Aio(unsigned int pin) {
47 m_aio = mraa_aio_init(pin);
53 mraa_aio_close(m_aio);
56 * Read a value from the AIO pin. Note this value can never be outside
57 * of the bounds of an unsigned short
59 * @returns The current input voltage, normalised to a 16-bit value
