Hello TI
We try to integrate MCAL SPI Driver (Version 08.06.02) into our basic SW project.
We did some experiment with the driver and we saw that the SPI is always in LOOPBACK Mode. We cannot change the mode.
Here is the configuration of the SPI driver:
SPI RECEPTION = Data[0] // SPI_PIN_D0 this is for Data Reception
SPI TRANSMISSION = Data[1] // SPI_PIN_D1 this is for Data Transmission
Here is an example:
we send data 0xAA
This is the result
The Data's are correct send; but we always receive the same data's at the same time. The send and receive pins are not same and are not connected together.
Why is there a loopback on the SPI driver? We shouldn't have MISO_DO; because we don't have slave on the other side.
Here is also a related code part :
If we comment this code part, it has no influence.
I think it is a small bug in the driver; but we need a fast fix for our development.
I would be appreciated, if this issue could be handled as soon as possible.
Thank you
best regards.
