This test does only covers cases where the Additive or Mulplicative expression ToPrimitive is a string.

实用的IGBT的RCD吸收电路，采用真实器件参数，做到基本无尖峰且吸收能量最小，保持开关管最小应力！！(Practical IGBT of RCD snubber circuit, using the real device parameters, so that almost no energy absorption peak and minimum, keep the switch minimum stress! !)

SSD1963 is a display controller of 1215K byte frame buffer to support up to 864 x 480 x 24bit graphics content. It also equips parallel MCU interfaces in different bus width to receive graphics data and command from MCU. Its display interface supports common RAM-less LCD driver of color depth up to 24 bit-perpixel.

说明：  进行温湿度传感在串口显示波特率为115200，也可以在lcd上显示需要添加相应的驱动文件(The baud rate of temperature and humidity sensor is 115200 on serial port, and the corresponding driver files can be added on LCD.)

基于51单片机，芯片stc89c52,使用PCF8591ad转换器的源代码(Based on 51 MCU, chip stc89c52, using PCF8591ad converter source code)

常见的单片机操作，IO，中断，定时器，低功耗模式等(io, interrupt, timer, low power mode and so on)

说明：  使用STM32的普通引脚软件模拟SPI通信，通过软件SPI操作WQ2516，已测试验证过！(Using STM32's general pin software to simulate SPI communication and operate WQ2516 through software SPI, it has been tested and verified.)

关于51单片机和dac7811芯片之间通信的程序，可以正确模拟SPI串口通信，写入数据(On communication between 51 single chip microcomputer and dac7811 chip procedures, can correctly simulate the SPI serial communication, write data )
