  • 14.Q&A
  • 15.Create a “hello word” task with MobileCam board Download LiteOS code from community Find“app_Init,” and begin your journey with LiteOS Run the board and you can find the “hello word” task is created. Set up hardware environments Config compiler like arm- huaweiliteoslinux-gcc on Linux server Set up software environments Create a new task, compile the project and porting the Bin file to the board. Realize your idea with LiteOS
  • 16.LiteOSDemo:Balanced car for video surveillance With LiteOS and it’s connection SDKs, we cansee: Seamless connecting(Zeroconfiguration) to gateway and controller(phone) via WIFI.  Fast response to the control command.  Fast development(<2 weeks, 2 people).
