visual basic serial port communication example

Recently in re-learning u/cos-ii, learning, to a small thing practiced hand is the best way to learn, so there is a serial port parsing module, is filled with my code base it,U/COS-II analog is the single-chip terminal serial analysis, the host computer serial debugging is written with QT, because the Windows C languag

The data in the experiment is already done, so I downloaded a brand-new zstack-2.5.1a to do the experiment, follow the steps, found a lot of problems.The first step is to configure the serial port.Mt_uartinit in the mt_uart.c ();　　BaudRate is set to 115200 (default is 38400), FlowControl is set to false. The second step, predefined macros.Mt_uartinit () There is a small　　1, 2 lines select different data processing functions according to predefined z
