Originally, ‘endTransmission’ was an f(void) function. This function returns 0 if successful, else returns error. Uint8_t endTransmission(uint8_t sendStop) “Wire.h” must be included to use the class function. TwoWire::beginĪddress: Set the I2C master mode with slave address value. TwoWire(uint32_t dwSDAPin, uint32_t dwSCLPin) ĭwSDAPin: The pin number on Ameba board to be set as SDA pin.ĭwSCLPin: The pin number on Ameba board to be set as SCL pin. Do nothing, use, and transmission(.) to force data transfer.
