    UART to output message - A simple program for beginners using Modus Toolbox2.1 with PSoC6(M4)


      Hi all,


      I am making some programs for beginners using Modus ToolBox 2.1. When migrating the development environment from PSoc Creator to Modus, I had a hard time creating a simple program. Especially, there are few simple samples using the Device Configuration tool.

      Here, a simple program for the M4 core of PSoC 6 using the Device Configuration tool of Modus Toolbox2.1 is introduced here.


      The environment is as follows.




      This time, it is a method to output a message on the terminal by using the UART function of SCB.


      Select the CY8CKIT-062-BLE kit from the New Application tool in the Quick Panel and use it based on what was created in the empty PSoC 6 app.


      About the pin setting, start the Device Configuration tool from the Quick Panel in the IDE of Modus Toolbox2.1, and set it according to the following procedure.


      Go to “Peripheral” tab.

      Check Serial Communication Block (SCB) 5, Name is "KIT_UART".

      Personality chooses “UART = 1.0”.

      Also set the parameters on the right. For communication settings, use the above settings (default) and set the following.

      Clock:8bit Divider 1 clk

      Rx:P5[0] digital_inout

      Tx:P5[1] digital_inout


      Now you can set Pin and Clock at the same time. Just in case, check the “Pin” and “Peropheral-Clocks” tabs.


      The program is as follows. The message is output by the Cy_SCB_UART_PutString() function.


      int main(void)
          cy_rslt_t result;
          cy_stc_scb_uart_context_t KIT_UART_context;
          /* Initialize the device and board peripherals */
          result = cybsp_init() ;
          if (result != CY_RSLT_SUCCESS)
          /* Turn on the UART */
          Cy_SCB_UART_Init( KIT_UART_HW, &KIT_UART_config, &KIT_UART_context );
          Cy_SCB_UART_Enable( KIT_UART_HW );
          Cy_SCB_UART_PutString(KIT_UART_HW, "Hello PSoC \n\r" );
          for (;;)


      Since I used TeraTerm as a terminal, the setting is described below.


      Note: “Port” is depending on the PC environment.


      It's easy. First, why don't you get used to Modus toolbox from this program?
