TMS570LS1224: I2C Interrupts for the TMS570

Hello,
There is an example code for TMS570LS31x_21x MCUs under HALCoGen example folders.
void i2cReceive(i2cBASE_t *i2c, uint32 length, uint8 * data) function was called first to setup receive operation.
This is from function declaration:
"Receive a block of 'length' bytes long and place it into the
* data buffer pointed to by 'data'. If interrupts have been
* enabled the data is received using interrupt mode, otherwise
* polling mode is used. In interrupt mode receive is setup and
* the routine returns immediately, i2cReceive must not be called
* again until the transfer is complete, when the i2cNotification
* callback will be called. In polling mode, i2cReceive will not
* return until the transfer is complete. "

void i2cSend(i2cBASE_t *i2c, uint32 length, uint8 * data) function is used for sending data. In interrupt mode transmission of the first byte is started and the routine returns immediately.

This is from functio declaration:
"Send a block of data pointed to by 'data' and 'length' bytes
* long. If interrupts have been enabled the data is sent using
* interrupt mode, otherwise polling mode is used. In interrupt
* mode transmission of the first byte is started and the routine
* returns immediately, i2cSend must not be called again until the
* transfer is complete, when the i2cNotification callback will
* be called. In polling mode, i2cSend will not return until
* the transfer is complete."

Hope this helps.

Best regards,
