Tool/software: Code Composer Studio

Hi sir/madam

we are using LAUNCHXL-F280049C launchpad, we try import SCI code from c2000 ware to ccs we see the output in putty terminal,we are able to get output when we are using the same gpio pins which are already written in code,now we need to change the gpio numbers for TX,RX ,we usie gpio_28 and gpio_02 (earlier in codeTX,RX pins are gpio-28,gpio-29) but we didn't get output,can you please help me to reduce this problem.

thank you

    Hello Rajeswari,

    Thank you for your question! Regarding this, would you be able to provide more details? It is possible that the configuration settings are not begin set properly for SCI-TX when changing to GPIO_02. Also, please make sure you are utilizing the latest C2000Ware version (please provide version used in the folder root, for example "C2000Ware_3_02_00_00").

    It will also be useful to provide waveforms (oscilloscope or logic analyzer) of the SCI-TX and SCI-RX to ensure that the data format/amplitude is correct.

    I look forward to hearing back from you!

    Regards,

    Vince

    Hello Rajeswari,

    The latest version of C2000Ware is actually C2000WARE_3.02.00.00. Please provide the following before we can assist with your issue:

    1. Code (please provide all code you are able to share)

    2. A list of all changes made from default C2000Ware example code

    3. Waveforms of the SCI-RX and SCI-TX pins ***crucial for debug to determine if the signal is occurring correctly***

    4. Hardware configuration

    Without these, it is difficult to determine what could be the source of the issue (as it could be potentially anything without having more details).

    Thanks,

    Vince
