Description: 温度的BCD码显示
在0809上显视的是电压值，所以必须将电压转换成温度值。LM35传感器的电压温度特性为“10mV/摄氏度”，经放大电路放大四倍后为40mV/摄氏度，因此对于255来说，每个数代表了20mV，也就是说电压值中的每个00000002代表了温度值中的00000001，由此可编出一张BCD码转换表，此部分程序如下：
-Temperature BCD code displayed in the 0809 significantly depending on the voltage value, so the voltage must be converted into temperature values. LM35 temperature sensor voltage characteristics 10mV/° C , by the amplifier circuit to enlarge four times the post-40mV/° C, so for example 255, each number represents a 20mV, voltage value that is to say each represents 00,000,002 temperature value of 00000001, which can be made available for out of a BCD code conversion table, this part of the procedures are as follows:
