这是个用矩阵键盘控制步进电机圈数和转速的程序，参数设定在触摸屏上显示(This is a matrix keyboard to control the stepper motor number of turns and speed program parameter settings on the touch screen display)

可以用指令控制选择信道，设置发射功率，发送数据包（长度可选），接收数据包（接收时延可设），CC2430复位,内部温度传感器读取，定时器时长控制。底层函数基本做好，如果要加入新功能，可自行更改。(You can select the channel with the command control, set the transmit power, transmit data packet (lengths), receive data packets (receiver delay can be set), CC2430 reset, the internal temperature sensor reading, the timer duration control. Basic underlying function well, if you want to add new features to make changes.)

气体传感器采样与无线数据传输并发送至电脑 cc2530,多通道数据传输，IAR版本为8.1(Gas sensor sampling and wireless data transmission and sent to the computer cc2530, multi-channel data transmission, IAR version 8.1)
