Audio Level Meter for USB + Serial RGB Backlight Character LCD Backpack

NewImage

Thanks to The Transmogrifox for writing in to share this project! See more on GitHub.

Spring-boarding from CanyonCasa’s work on hacking the USB LCD backpack an audio-level-metering command was added to the LCD function.

The audio level meter splits each row into 2 audio channels and automatically generates the custom characters necessary to display 2 seemingly independent meter bars. The implementation also includes exponential decay, so all you need to do in the application code is detect a max value over an interval, map it from 0 to nCOLS, and send it over USB or serial to the LCD backpack and it will “bump” the meter bar.

Additionally there is a new command to disable the config blink, a setting which is saved to EEPROM so this feature is disabled when you are done with development & testing and want to have full control over what is (or is not) displayed at power-up.

See the referenced github page README files for more in-depth descriptions.
