2.2 Foundation Services Generated Code

To generate this project using the Foundation Services library, follow these steps:

  1. Create a new MPLAB X project.
  2. Open the MCC from the toolbar (information on how to install the MCC plug-in can be found on the Microchip website).
  3. Go to Project Resources > System > System Module and use the following configurations:
    • Oscillator Select: HFINTOSC
    • HF Internal Clock: 4 MHz
    • Clock Divider: 4
    • In the WDT Enable field, in the WWDT tab, ensure WDT Disable is selected
    • In the Programming tab, ensure Low-Voltage Programming Enable is checked
  4. In Device Resources under Libraries, find Foundation Services, expand it and double-click UART to add it to the project.
  5. Click the + button at the bottom to add a new Foundation Services federated UART.
  6. Select EUSART2 from the UART drop down in Foundation Services.
  7. Open the Pin Manager > Grid View window, select UQFN40 in the MCU package field and select pin RD0 EUSART TX.

  8. Click Generate in the Project Resources tab.
  9. In the main.c file, which was generated by MCC:
    • Uncomment the line that enables global interrupts and the one that enables peripheral interrupts
    • Add the following code in the main function (replacing the existing while(1) loop):
      char msg[] = "Hello world\r\n";
      while (1)
      {
          for(uint8_t i = 0; i < strlen(msg); i++)
          {
              uart[UART0].Write(msg[i]);
          }
      }
  10. Use MPLAB X Data Visualizer as described in the appendix, How to Receive Data in MPLAB Data Visualizer.
