well, i'm converting an analog signal (voltage difference), sent from a temperature sensor (thermocouple).. i need the signal to be in BCD so that i can display them on 7 segment.. i know that ordinary A/D converter only converts to binary.. like u mentioned, i need to convert them into BCD.. but i don't know how..
the second problem is that.. when i convert the analog signal, the resulting binary value represents the voltage difference from the sensor (am i right?), not the actual temperature value. so i figured that i need to have a constant that relates the voltage difference and the temperature, which then the constant can be multiplied to the voltage difference (in the form of BCD) so that the BCD represent the temperature value.
this is how i see and plan to tackle my project.. correct me if i'm wrong. any suggestions or hints are deeply appreciated.
