Sometimes need to do the framework integration of things, you need to integrate other clients like components into a client, similar to a software integration platform client, unified with a central management of the client to do similar to the control panel of the same thing to invoke different software. At this point, the corresponding different click-icon events must be embedded in the main interface. The following is a simple description of the co

After six months of study and debugging, I finally wrote a simple GIS. On the ARM development board, I chose QT/Embedded 2.3.7 as the graphic development interface. I debugged the touch screen yesterday, finally, a little result is coming out. I'm very happy. I just published a message to celebrate it. Many people ask me for code reference, but because it is a project, it cannot be used for reference. So

1. Preparations First, install the GCC tool chain and the development environment. You can check the previous steps. You have to compile the kernel. Generally, the Development Board has the kernel. Now I do not know how to configure the kernel. You can only compile the kernel according to the default settings of the Development Board. uboot needs to be compiled before compilation, it is recommended that new users like me learn to write drivers first and learn Kernel configuration pruning slowly.
