Hi,

1) In order to send the data you need to use:

   LPI2C_DRV_MasterSendDataBlocking(instance, txBuffer, txSize, true, timeout);

2) To receive data from a specific address you need first to send the command without sending stop and then requesting the required amount of data(This operation will send a repeated start on the bus). E.g.

   LPI2C_DRV_MasterSendDataBlocking(instance, txBuffer, txSize, false, timeout);

   LPI2C_DRV_MasterReceiveDataBlocking(instance, rxBuffer, rxSize, true, timeout);

Please fill the instance, txBuffer, txSize, timeout, rxBuffer and rxSize parameters according to your application.

Best regards,

Rares
