LAUNCHXL-TMS57004: Pin Mapping

LAUNCHXL-TMS57004: Generating include files in halcogen for TMS57004

Part Number: LAUNCHXL-TMS57004
Other Parts Discussed in Thread: BQ76PL455-Q1, BQ76PL455A-Q1, BQ76PL455A, HALCOGEN

Dear All,

I am developing a BMS using BQ76PL455 EVM and TMS-57004 launchpad. By editing the "sys_main.c" file in the source folder of example code( bq76pl455-q1 evm) I am able to read voltage of cells.

I have made a battery pack of 8 cells in series.

In the example code, they have include gio.h, sci.h and rti.h.So I have enabled gio, rti and sci drivers. 

For rti we enable RTI compare 1 in VIM module..

For UART we set the baud rate of 250K and enable channel 13 in VIM module.

I have includes in pl455.h, pl455.c, datatypes.h and swi_util.h from example code but I am not getting any output in this case.

I am including both the project below.

1. bq76PL455A-Q1 Example Code1 ( which is working correctly)

2. Battery ( which is not giving any output).

Please help in resolving the issue.

2350.Battery.rar

8510.bq76PL455A-Q1 Example Code1.rar

Regards,

Gunit

    Hello Gunit,

    What are the differences between those two projects (battery, and bq76PL455A_Q1 example)? I had a quick review of the code, sys_main.c in both project are the same. The sys_vim.c shows that you don't enable SCI interrupt (channel 13) in battery project.

    What do you mean there is no output?

    Sir,

    Thanks for replying.

    In the project named battery the include files are generated by me in halcogen whereas in project bq76pl455A-Q1 example the include files are example code given in TI website.

    In the project named battery we forget to enable SCI interrupt ( Channel 13) while generating code in halcogen so we created a new project named battery 1 but still we are not getting any output.

    I am also attaching the new project "battery1" along with the screenshot of outputs for both projects (bq76pl455A-Q1 and Battery1).

    Output of bq76pl455A-Q1  project:

    Output of battery1  project:

    Sir,

    I am able to resolve the issue actually I have configured 2 stop bits in UART that's why the slave was not responding. But I changed stop bit to 1 the slave is now responding.
