# 🌶️🌶️ - Giant Gecko Power Mode
2+
3+
This samples shows how to use the Power Mode on Silabs Giant Gecko MCU's.
4+
5+
## Build the sample
6+
7+
1. Start Microsoft Visual Studio 2022 (VS 2019 should be OK too) and select `File > Open > Project/Solution`.
8+
1. Starting in the folder where you unzipped the samples/cloned the repository, go to the subfolder for this specific sample. Double-click the Visual Studio Solution (.sln) file.
9+
1. Press `Ctrl+Shift+B`, or select `Build > Build Solution`.
10+
11+
## Run the sample
12+
13+
The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.
14+
15+
### Deploying the sample
16+
17+
- Select `Build > Deploy Solution`.
18+
19+
### Deploying and running the sample
20+
21+
- To debug the sample and then run it, press F5 or select `Debug > Start Debugging`.
22+
23+
> **Important**: Before deploying or running the sample, please make sure your device is visible in the Device Explorer.
24+
25+
> **Tip**: To display the Device Explorer, go to Visual Studio menus: `View > Other Windows > Device Explorer`.
