这个代码在点阵上显示相应的图形。先将程序写入单片机，然后运行，显示相应的图片。(This code displays the corresponding graphics on the lattice. Write the first program the microcontroller, then run, display the corresponding picture.)

基于MSP430舵机控制程序，SG90舵机，由PWM进行控制(MSP430-based steering control procedure, SG90 servos controlled by the PWM)

stm32数组转二进制工具，在Keil下运行 1.输入文件内容必须包含类似于{0xff,0xff}这样的c语言数组格式，才能正常转换。大括号和前导符“x”是必须的。 2.支持8位和16位数据。 3.支持4个字节的长宽信息，方便Image2Lcd程序输出的图片转换成Bin。 4.支持成对“/”符号包含注释信息，若文件内容只有单个“/”,后果自负。 5.支持头四个字节的宽高信息互换存储位置。(stm32 array to binary tools, running in Keil 1 input file must contain similar {0xff, 0xff} c language such array format to normal conversion. Braces and leading character "x" is a must. 2 supports 8-bit and 16-bit data. 3 supports 4-byte length and width information to facilitate Image2Lcd program output image into Bin. 4 support paired "/" symbol contains annotation information, if only a single file contents "/" peril. 5 support the first four bytes wide exchange of information stored in a high position.)
