In this chapter we will look at using the PIC to measure real-world signals such as signals from pressure, temperature, and speed. It will cover using the three registers that control the ADC and receiving an analogue input and displaying it as a binary value.

After reading this chapter, you will be able to use analogue inputs.

Using Analogue Inputs

As well as digital inputs, which are usually just on or off, 5v or 0V, PICs can use analogue inputs. These are inputs that can ideally take up any voltage within the range of the PIC, normally any voltage between 0 and 5V. I say ...
