CCS/BQ76PL455A-Q1: RX

WORM0451

Part Number: BQ76PL455A-Q1
Other Parts Discussed in Thread: BQ76PL455A

Tool/software: Code Composer Studio

I have a problem with UART recieve RX. The hardware is EVM1402 and launchpad TMS750432. The software is from http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=tidcbz0&fileType=zip

and my question is about RX. The screenshot of main is shown as follows.

and the code we edited is as follows.

The code stopped in pl455.c and could not go into while{}

And the RX pin could not receive wave either.

What can I do to receive sampled value of voltage. Thanks.

Hello Jinwei,

If you would like to go beyond that we do not have any further resources but I can point you in the right direction.

For interfacing the device with other protocols or outputting data somewhere else that would be best to reach out the TMS570

support page as this is not bq76pl455a related.

Thanks!

Andy

Hi Andy
We have already download all the related documents, and the example code is from the web site you recommended. However, we could not get the right RX information. We have spent a lot of time on it. Will you/some one related please test the code, and give some helpful advice! Thanks.

Hi Andy

Would you please provide the correct sending and recieving timing map for single device and response mode. For example, when the sampling order is sent, what is the timing map, and what is the corresponding timing for RX.

Thanks

Hi WORM0451,

The information you are looking for is shown in the datasheet for the bq76pl455a and the example commands are located in the Software Design Reference Guide.If you are using some custom hardware, then please make sure you have double checked with our reference schematics.

Regards,

Taylor
