| This function is implemented only for Linux and Mac versions of the library. |
The U2C_RW_Pack() function executes a list (pack) of I2C read/write transactions. All transactions are sent to U2C-12 device in a single USB transfer block.U2C_RW_Pack() waits until all I2C transactions are completed and returns each transaction result code in pTransaction[i].rc element. I2C transactions are performed sequentially in the same order as they are in the pack. Take care to pack correct sequence of the transactions. For instance attempt to read/write after write to I2C EEPROM may timeout because of the internal EEPROM write cycle.
Parameters:
- hDevice
Handle to the U2C-12 device.
- pTransaction
List of I2C transactions.
- count
Number of I2C transactions in the pTransaction list.
Return values:
U2C_SUCCESS
Operation was successfully completed and pList is filled with valid data.
U2C_HARDWARE_NOT_FOUND
U2C-12 device referenced by hDevice handle was not found.
U2C_BAD_PARAMETER
I2C transactions list is too big.
