Example

#include <107-Arduino-AS504x.h>
/* ... */
static SPISettings const AS504x_SPI_SETTING{1000000, MSBFIRST, SPI_MODE1};
/* ... */

                               [](){ SPI.endTransaction(); },
                               [](){ digitalWrite(AS504x_CS_PIN, LOW); },
                               [](){ digitalWrite(AS504x_CS_PIN, HIGH); },
                               [](uint8_t const d) -> uint8_t { return SPI.transfer(d); },
                               delayMicroseconds);
/* ... */
