Im new to microcontroller and i face some problem in it. Currently, I noe how LM35 detect temperature and send the corresponding temperature to the AT89S51. Since ADC0808 output is 8 bit binary number, what should i do to include decimal point of a temperature?
For example, if LM35 detect 26.4 Celcius, it is ezy to let AT89S51 to read 26 celcius thru ADC0808, but what shud i do to read 26.4 Celcius?
Plz help me....thx...
