Conditional Method Design Pattern
In embedded systems programming, conditional statements are frequently used to make decisions based on certain conditions. The most common conditional statements in the C programming language are if, else if, and else.
Problem Statement:
Let’s see an simple example of conditional patterns in C for embedded systems:
C
#include <stdio.h> int main() { // Assume a sensor reading in an embedded system int sensorValue = 75; // Threshold values for decision-making int thresholdLow = 50; int thresholdHigh = 70; // Conditional statements to make decisions based on the sensor reading if (sensorValue < thresholdLow) { // Perform action when the sensor value is below the low threshold printf ("Sensor value is too low. Take corrective action.\n"); } else if (sensorValue >= thresholdLow && sensorValue <= thresholdHigh) { // Perform action when the sensor value is within acceptable range printf ("Sensor value is within acceptable range. No action needed.\n"); } else { // Perform action when the sensor value is above the high threshold printf ("Sensor value is too high. Take corrective action.\n"); } return 0; } |
Output
Sensor value is too high. Take corrective action.
Explanation :
- We have a sensor reading represented by the variable sensorValue.
- We set threshold values (thresholdLow and thresholdHigh) to define the acceptable range for the sensor reading.
- The if, else if, and else statements are used to check different conditions based on the sensor value.
- Depending on the condition met, different actions are taken. For an embedded system, these actions might involve adjusting system parameters, activating or deactivating devices, or triggering alarms.
Design Patterns for Embedded Systems in C
When working with embedded systems in C, there are so many design patterns that are particularly very useful. Many design patterns can be applied to embedded systems development in C.
