C++ (Cpp) i2c_write_word_data Examples

Example #1

File: LTC2943.cpp Project: bayarveli/Linduino-LTC2943-Arduino-Library

// Write a 16-bit code to the LTC2943.
int8_t LTC2943_write_16_bits(uint8_t i2c_address, uint8_t adc_command, uint16_t code)
// The function returns the state of the acknowledge bit after the I2C address write. 0=acknowledge, 1=no acknowledge.
{
  int8_t ack;

  ack = i2c_write_word_data(i2c_address, adc_command, code);
  return(ack);
}
