bool8_t I2CWrite ( LibTiePieHandle_t  hDevice,
uint16_t  wAddress,
const void *  pBuffer,
uint32_t  dwSize,
bool8_t  bStop 
)

Write data to a specified address on the I2C bus, using a specified I2C host.

Parameters
[in]hDeviceA device handle identifying the I2C host.
[in]wAddressThe I2C address to write to.
[in]pBufferA pointer to the write buffer.
[in]dwSizeThe number of bytes to write.
[in]bStopIndicates whether an I2C stop is generated after the transaction, when BOOL8_TRUE, an I2C stop is generated, when BOOL8_FALSE not.
Returns
BOOL8_TRUE if successful, BOOL8_FALSE otherwise.
Status values
INTERNAL_ADDRESS The requested I2C address is an internally used address in the device.
BIT_ERROR The requested I2C operation generated a bit error.
NO_ACKNOWLEDGE The requested I2C operation generated "No acknowledge".
INVALID_HANDLE The handle is not a valid I2C host handle.
OBJECT_GONE The object indicated by the handle is no longer available.
LIBRARY_NOT_INITIALIZEDThe library is not initialized, see LibInit().
SUCCESS The function executed successfully.

uint16_t  wAddress,
uint8_t  byValue1,
uint8_t  byValue2 
)

Write two bytes to a specified address on the I2C bus, using a specified I2C host.

An I2C stop is generated after the transaction.

Parameters
[in]hDeviceA device handle identifying the I2C host.
[in]wAddressThe I2C address to write to.
[in]byValue1The first byte value to write.
[in]byValue2The second byte value to write.
Returns
BOOL8_TRUE if successful, BOOL8_FALSE otherwise.
Status values
INTERNAL_ADDRESS The requested I2C address is an internally used address in the device.
BIT_ERROR The requested I2C operation generated a bit error.
NO_ACKNOWLEDGE The requested I2C operation generated "No acknowledge".

bool8_t I2CWriteByteWord ( LibTiePieHandle_t  hDevice,
uint16_t  wAddress,
uint8_t  byValue1,
uint16_t  wValue2 
)

Write one byte and one word to a specified address on the I2C bus, using a specified I2C host.

An I2C stop is generated after the transaction.

Parameters

Returns
BOOL8_TRUE if successful, BOOL8_FALSE otherwise.
Note
Bus data is regarded big endian, host endian data will be converted to big endian.
