This tutorial shows how to create a basic “Blinking LED” project for the Atmel SAMD21-Xplained-Pro board. If you are using a different Atmel board with an ARM Cortex-based MCU, simply choose a different MCU name and\u00a0 specify where your LED is connected. You can find the full listing of supported Atmel devices here: http:\/\/visualgdb.com\/hwsupport\/<\/a><\/p>\n

Before you begin, install Visual Studio and VisualGDB 5.1 or later.<\/p>\n

    \n
  1. Start Visual Studio and launch the VisualGDB Embedded Project Wizard:\"01-newprj\"<\/a><\/li>\n
  2. Proceed with the default settings on the first page of the wizard:\"02-msbuild\"<\/a><\/li>\n
  3. On the next page select the ARM toolchain and select your Atmel device. VisualGDB will automatically download the latest Atmel BSP with all the necessary files:\"03-device\"<\/a><\/li>\n
  4. On the Sample Selection page choose the GPIO port where your LED is connected. On the Amel SAMD21-xplained-pro the orange LED is connected to port PB30:\"04-sample\"<\/a>The checkboxes below the LED parameters allow automatically including various libraries provided by Atmel into your project. Note that not all libraries are compatible with all devices.<\/li>\n
  5. Finally select the OpenOCD debug method. Plug in your board and press “Detect”. VisualGDB will automatically detect the necessary settings:\"05-cmsisdap\"<\/a>If the device does not get auto-detected, update your OpenOCD package via Tools->Embedded Tools Manager.<\/li>\n
  6. Press “Finish” to generate the project. Build it with Ctrl-Shift-B:\"06-build\"<\/a><\/li>\n
  7. Press F5 to start debugging. Note how the orange LED on the board begins to blink:\"board\"<\/a><\/li>\n
  8. Now we will try out the Live Variables feature to see what is happening in the program without stopping it. Modify the loop inside main() to modify a global variable declared as follows:\n
    int g_Counter;<\/pre>\n
    Then start debugging and add g_Counter to the Live Variables window. Enable plotting to see how the variable is incremeneted with each step:\"07-counter\"<\/a><\/li>\n
  9. You can set a breakpoint in your code to stop the program and check its state. Note how VisualGDB automatically expands the values of preprocessor macros based on the current location:\"08-step\"<\/a><\/li>\n
  10. You can include other Atmel frameworks (e.g. drivers for various peripherals) into your project by opening the VisualGDB Project Properties dialog and enabling them on the Embedded Frameworks page:\"frameworks\"<\/a><\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
