CC2652P7: [Custom board]:SPI master and slave communication verification

Thanks Chen

Hi Clement,

Tried controller and peripheral examples together.Configured input/output pins according to my design.

Unfortunately, code execution in the master is stuck at the following:

What else should I cross check?

Thanks

Hi,

May I kindly ask if you have requested a design review?  https://www.ti.com/tool/SIMPLELINK-2-4GHZ-DESIGN-REVIEWS

I would also recommend to monitor the pin with a logic analyzer to verify if the voltage level is correct.

Please also consider reviewing the SPI debugging guide https://software-dl.ti.com/simplelink/esd/simplelink_cc13xx_cc26xx_sdk/7.10.00.98/exports/docs/ble5stack/ble_user_guide/html/ble-stack-5.x-guide/debugging-index.html#spi

Best regards,

Hi Clement,

Did not request for a design review.

Unfortunately, I do not have access to these pins since all the master and slave chips are encapsulated in a module.

Thanks

Changed the Chip Select configuration in syscfg file.

Chip Select for Master device is configured the pin as follows:

Chip Select for the Slave device is configured as follows:

...

Here is the output:

Starting the SPI controller example
This example requires external wires to be connected to the header pins. Please see the Readme.html and Board.html for details.

Controller SPI initialized

Controller received:  from peripheral, msg#: 0

Unfortunately, upon chip reset, I am not able to see the same result.

Thanks

Karthik

Thanks Clement. Will do. Appreciate your support.

Hi Clement,

DIO_12 is chip select pin ( output of SPI controller, output strength configured to medium in syscfg)

DIO_13 is SPI peripheral ready pin ( which is an input to the SPI controller).

On both the lines there is a pull up of 51k Ohms. Is this ok?

Thanks

Karthik

Hi Karthik,

May I kindly ask you to open a separate thread to discuss hardware design questions? I am afraid I am not the more knowledgeable person to answer this kind of question.

Appreciate your comprehension.

Best regards,

Sure, thanks.
