1.1.2.4.5 DRV_I2C_TransferSetup Function

bool DRV_I2C_TransferSetup ( DRV_HANDLE handle, DRV_I2C_TRANSFER_SETUP* setup )

Sets the dynamic transfer setup of the driver.

This function should be used to update any of the DRV_I2C_TRANSFER_SETUP parameters for the selected client of the driver dynamically. It is mainly helpful for multi client scenario where different clients need different setup like clock speed. The DRV_I2C_TransferSetup function must be called before submitting any I2C driver read/write requests.

DRV_I2C_Open must have been called to obtain a valid opened device handle.

In case of asynchronous driver, all transfer requests from the queue must have been processed.

None.

// myI2CHandle is the handle returned by the DRV_I2C_Open function.
DRV_I2C_TRANSFER_SETUP setup;

setup.clockSpeed = 400000;

DRV_I2C_TransferSetup ( myI2CHandle, &setup );

None.
