Summary

In this chapter, we saw ADC converters and their usage in a practical application, such as detecting dangerous gas using a proper gas sensor. We saw how to use them for a single analog-to-digital conversion as is and how to use them in continuous conversions driven by a software or hardware clock (or event) source.

In the next chapter, we'll see another important device class that can generate an analog output from a digital one, even if in a square waveform, useful to control several devices: PWM devices.
