To illustrate the range of timing requirements that can be encountered, let's consider a few different systems that acquire readings from analog-to-digital converters (ADCs).
The first system we'll look at is a control system that is set up to control the temperature of a soldering iron (as seen in the following diagram). The parts of the system we're concerned with are the MCU, ADC, sensor, and heater.
The MCU is responsible for the following:
- Taking readings from a temperature sensor via the ADC
- Running a closed-loop control algorithm (to maintain a constant temperature at the soldering iron tip)
- Adjusting the output of the heater as needed
These can be seen in the following diagram:
Since the temperature of ...
