Compiler/TMS570LS0714: Programming Sci2

Part Number: TMS570LS0714
Other Parts Discussed in Thread: HALCOGEN

Tool/software: TI C/C++ Compiler

Hey guys, 

I was trying to mimic the tutorial made by TI here () but for some reason when I try to run my code the terminal won't print anything. When I start to type, the interrupt will sometimes prompt the terminal to print '%'. Any advice?

    Hello Hayes,

    There is a SCI sample code in HalCoGen example.

    HALCoGen 4.6.x or later version --> Help --> Help Topics

    In help window, you will see example_sci_uart_9600.c under example. Follow the instruction to create a project.

    The example that QJ pointed to may be more clearly documented, but for the one on Youtube that you noted, the issue is likely one of two potential root causes. It is probably that you are either operating at the wrong baud rate causing data corruption in the transmitted data or the data that you are sending is not ascii data. i.e., you would need to convert the characters received by the application from a hex value to its asci character then send it back out on the Tx line back to the terminal window.
