Function Documentation

readBit()

int8_t readBit	(	uint8_t	devAddr,
		uint8_t	regAddr,
		uint8_t	bitNum,
		uint8_t *	data
	)

Read a single bit from an 8-bit device register.

Function is deprecated!

Internal conversion:

int8_t readBit(uint8_t devAddr, uint8_t regAddr, uint8_t bitNum,
  uint8_t *data) {

    int8_t status;
    status = !twiWrapper_readBit(2*devAddr, regAddr, bitNum, data);
    *data&= _BV(bitNum);
    return status;
}
