MSP-EXP430FR5739-User-Experience

本设计主要实现用按键控制步进电机四相单拍、四相双拍和四相八拍三种方式切换， 正、反转及其加、减速，并能在LCD上显示其运行状态（速度和转向）。(The design of the main keys to achieve control of stepper motor with a single shot four-phase, four-phase two-and four-phase eight-shot shoot three ways to switch Positive, reverse its acceleration, deceleration, and in its operational status on the LCD display (speed and steering).)

此程序为4*4矩阵键盘，键盘自身不带电源电阻，八个接线，在程序中进行需进行软件拉高拉低以便按键扫描。 应用单片机为MSP430F5529。(4* 4 matrix keyboard without power resistors MSP430F5529)

基于单片机的函数信号发生器的C语言代码，自己做的(Function signal generator based on single chip microcomputer C language code )

MCU图片解码，使用STM32对JPEG图片解码，(STM32 JPEG decoder code,)

上位机通信-配合XTMonitor显示温度等(PC communication- with XTMonitor display temperature, etc.)

说明：  用4*4矩阵键盘给液晶1602送四位数，其中第四行按键设置为功能键，按键显示可调对应位的数字(With 4* 4 matrix keyboard to send the four-digit LCD 1602, the fourth line of buttons is set to function keys, adjustable button displays the corresponding number of bits)

direct sparse solver for linear equations

TFT240320彩色液晶显示屏显示程序，库文件中定义了其常用的操作函数，可直接在主函数中调用(TFT240320 color LCD display program, the library file defines its common operating functions that can be invoked directly in the main function)

振幅调制,角度调制，频率调制等几个源程序，模拟通信系统(Amplitude modulation, angle modulation, frequency modulation, such as source code, analog communication systems)

99秒马表，在Proteus设计两个数码管动态显示及一个键盘SP。在ucos下结合keil完成开始时，显示“00”，第1次按下SP后就开始计时。 第2次按SP后，计时停止。第3次按SP后，计时归零。 (99 seconds stopwatch, two in the Proteus design dynamic digital tube display and a keyboard SP. Keil in combination ucos completed under the beginning of the show " 00" , 1st timer after pressing the SP. 2nd by SP, the time to stop. The 3rd by the SP, the time zero.)
