6.2. Connecting to the Device and Downloading Firmware

This section describes how to open the IDE, open and build a project, connect to a device and download the firmware.

1.Open the Silicon Laboratories IDE from the Start → Programs → Silicon Laboratories menu.

2.In the IDE, go to Project → Open Project.

3.Browse to the default location, C:\SiLabs\MCU\ToolStick\F321DC\Firmware\.

4.Select F321DC_FeaturesDemo.wsp and click OK.

5.In the IDE, select Project → Rebuild Project.

6.Go to Options → Connection Options.

7.Select “USB Debug Adapter” for the Serial Adapter and “C2” for the Debug Interface, and then click “OK”.

8.Go to Debug → Connect.

9.Download the code using the download button on the menu bar or use alt-D.

Once these steps are completed, the firmware is built into an object file (step 5) and downloaded to the device (step 9). The device is now ready to begin executing code. If all of these steps were followed successfully, the “Go” option is enabled in the Debug menu. A green circle icon in the IDE toolbar also indicates that the device is ready to run. If one of the steps leads to an error, make sure that the ToolStick is properly inserted in a USB port and start again with step 6.

6.3. Running and Stopping Code Execution

Once the IDE is connected to the device and the firmware is loaded, the IDE can start and stop the code execution. The following steps can be performed using the buttons on the toolbar or using the options in the Debug menu.

1.To start code execution, click the green “Go” button on the toolbar or use the Debug → Go menu option. The green LED on the daughter card will start to flash. The debug commands in the IDE (single-step, multiple-step, set breakpoint, and others) are disabled when the device is running. While the firmware is running, the potentiometer on the daughter card can be turned to alter the blinking speed of the LED. The switch labeled S1 can also be pressed to toggle the ADC on and off. When the ADC is off, the blink rate or brightness of the LED will not change.

2.To stop code execution, click the red “Stop” button on the toolbar or use the Debug → Stop menu option. The device will halt code execution and all of the registers and pins on the device will hold their state.

All debug windows and watch windows are refreshed when the device is stopped. If any of the values in these windows have changed since the last time the device was halted, the new value is shown in red text instead of black text.
