最简单的20键PS/2键值读取程序，PS/2的clk接INT0，data接P1_0--A simple read/write program from 20-keys PS/2 keyboard. PS/2 s clk connects to INTO and data connects to P1_0.

是一个展厅灯光控制的软件，用的PIC16F73。-Hall is a lighting control software, using PIC16F73.

该数控直流电流源以精密压控电流源为核心、用单片机、DAC组成控制电路，引入“S类”反馈控制功率放大电路，实现超精密电流控制、具备精准的扩流能力、低失调、有步进、同时带有 丰富扩展功能的精密电流源。经过ADC采样，完成输出电流显示功能，并使输出范围覆盖0～2A，是理想的电流源解决方案。-The CNC precision DC voltage-controlled current source to current source at the core, with single-chip, DAC control circuit components, the introduction of " S-type" feedback control circuit power amplifier to achieve ultra-precision current control, with precise flow capacity expansion, low disorder, there is stepping at the same time and expanded with rich precision current source. ADC sampling after completion of output current display, and output cover 0 ~ 2A, the current source is an ideal solution.
