/* 功能：该程序可实现对ADC0832的控制，包括，启动ADC，选择输入通道，输入信号的模式《单端输入，或差分输入》

/* 并将采集到的数据进行处理，将读出的16进制转换为10进制形式 ，即程序中变量b，s，g的值

/* （与该程序相适应的硬件电路，P3_4-〉cs；P1_0->clk P1_1->DI&DO 参考电压与电源为同一个输入端）

/* 最小输出电压：0.00V；最大输出电压：5.10v 分辨率：0.02v 误差：+/-0.01v

/*

/* 该程序已通过调试,其中show_value()自函数用于显示电压值-/* Function: the program can be realized on the ADC0832 control, including, to start ADC, input channel selection, input signal mode " single-ended input or differential input" /* collected and processed data will be read out 16 hexadecimal form converted to 10-band, that is, process variables b, s, g the value of/* (with the program to adapt the hardware circuit, P3_4->　cs　P1_0->　clk　P1_1->　DI & DO　reference voltage and power for the same input)/* Minimum output voltage: 0.00V　maximum output voltage: 5.10v resolution: 0.02v error:+ /-0.01v/*/* The program has been through the debugger, which show_value () since function used to display voltage values
