As i checked the tramsimt.c source code and the MSO4 seriers with DPO 4AUTO decode oscilloscope can not analysis the signal .
as below attachmentsls. help me .
Sorry I am confused on this question.
Do you mean the code/MCU itself works fine and you only could not get the osciloscope could not analyeze the signal correctly?
On the TB board I confirmed the example code works fine.
Please follow the text guide in the source file to test this example.
I could see P0.7/P0.6 signal (PORT 0 'A') on side A of the TB board.
