HyperTerminal is a universal serial interaction software with Windows operating system, which can be configured for router switches and so on. Use a modem, a 0-demodulation cable, or an Ethernet connection, and then call this program to connect to other computers, Telnet sites, bulletin board systems (BBS), online services, and hosts. We can use it to debug the circuit is feasible. Embedded

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
