10.6 Summary

This chapter has described the use of 7-segment LED displays in microcontroller based projects. At the beginning of the chapter, a project using a single-digit display is given. In later sections, the use of 2 and 4 digit multiplexed displays are described in projects. Finally, the operation of a 4-digit 7-segment display, with built-in serial driver, is described in a project to count external interrupt based events.
