    Problem when changing UART baud rate in run time

    ctm.ctm

      Hi every body,

         

      I'm doing a project with CY8C24123A, PSoC designer 5.4, using user modules: UART, Counter8 (determine working frequency for UART).

         

      Contents:

         

      - PSoC receive data from another circuit (P0.4 RX)

         

      -Then, PSoC send data to PC via RS232 circuit (P0.5 TX)

         

      -When receiving data, baud rate is 4800; when sending data, buad rate is 9600

         

      If I don't change baud rate (4800) when PSoC running, PSoC works well (receive or send data OK, I can check data on PC, I'm using Terminal 1.9b).

         

      If I change baud rate when PSoC running,  PSoC can't work as I want. No data on the PC! At forum, I knew that I can change UART baud rate in run time of PSoC. 

         

      Can you check my project, please? Have you another solutions? Please tell me!

         

      Many thnanks!
