    matlab 生成 测温电阻  Rt表
    由 B 值可以推导出不同温度 t 下的电阻值 R = R0 * exp(B*(1/t - 1/T0)); 其中 R 为温度 t 下的电阻值 R0 为 25 度时的电阻值 T0 为 25 度 注:上述温度值都应是开氏温度,也就是说,需要加上绝对零度值 273.15 下面是从 0~100 度,间隔 0.1 度生成的 Rt 表, B 值,上拉电阻值可以修改成所需要的。 K = 273.15; B = 3950; T0 = K + 25; R0 = 10000; % 25 度时的阻值 Ru = 5000; % 上拉电阻 i = 0:1023; outstr = sprintf(' /* B const %d */ \n const Rt = {'; %outstr = ; t = i / 10 + K; R = R0 * exp(B*(1./t - 1/T0)); Vo = 3.3 * R./(Ru+R) Rt = round( Vo / 3.3 * 4096); for j = 1:length(Rt) if mod(j,16) == 0 outstr = ; else outstr = ; end end outstr = plot(i/10,Rt) outstr = sprintf('B %d Rpu %d ',B,Ru); Title(outstr) /* B const
