代码说明：

  通过单片机按键选择输出信号类型及要求输出量,在LED显示器件上指示信号类型及设定数值.系统工作电源±15V ， ±5V 。恒流电流输出0.0～8.0mA, 负载电阻≤500Ω。3． 稳压电压输出0.0～5.0V，电流负载能力≤100mA.电压及电流输出在充许负载范围内误差小于5％FS。电压及电流输出须共用一个输出正端, 输出负端为地。输出电压及电流设定精确到二位十进制数。 (Through Singlechip button to choose the type and requirements of the output signal output, in the LED display on the instructions of the signal type and set the value. System power supply ± 15V, ± 5V. Constant current output 0.0 ~ 8.0mA, the load resistance ≤ 500Ω. 3. Regulator output voltage 0.0 ~ 5.0V, current load capacity ≤ 100mA. Voltage and current output in the framework allow the load error is less than 5 FS. Output voltage and current output is required to share a client, the output of negative side for the land. Output voltage and current settings accurate to two decimal number.)
