s_out_pop.m

Matlab是常用的演草纸式编程工具

function v_code_feedback=s_out_pop(n,v)

%v is the value of the voltage
%n is the number of the channel
%v_code=32768+((v*8.8/1.9-2.5)*10^4/2);%计算5622的电压码,加运放
v_code=32768+((v-2.5)*10^4/2)%计算5622的电压码
s = serial('COM1');
fopen(s)
set(s,'DataBits',8)
s.BaudRate=2400;
fwrite(s,16*(n-1),'uint8')
fwrite(s,v_code,'uint16')
s.BytesAvailable;
v_code_feedback = fread(s,1)
s.BytesAvailable;

fclose(s)

delete(s)
