July 16, 2012 -- Microcontrollers are used widely in current digital TV designs to provide mechanisms to direct the tuner to access specific frequencies, receive IR inputs from remote controls, vary the speaker sound output, controls the front panel mechanical switches and LCD/LED displays.
In this article, the use of programmable SOCs devices will be described as an alternative in the design of a single-board solution for tuning analog and digital tuner frequency using I2C interface and receive IR inputs from the remote control using PSoC Creator's IR receiver component to vary speaker sound output via a direct drive LCD/ LED display for front panel. It will also show how the designer can use a PSoC's capacitive sensing technology to replace mechanical buttons on the keypad.
