Re: Program to subtract two results of GPiO pin inputs

Im new to this and still understanding the languages. So the way im reading the temperatures is using the bash language through terminal?

What are the advantages to using python language and again how would I create a program to do something like im trying to do?

Re: Program to subtract two results of GPiO pin inputs

I am using cat to retreive the signal

cat /sys/bus/w1/devices/28-xxxx/w1_slave

This returns t= XXXX

I do this for each connected temperature probe. Now how would I create a script to take the difference?
