SparkFun Forums 

Where electronics enthusiasts find answers.

Questions &/or issues related to products in the LCDs and OLEDs category should be posted in this forum.
My application requires quick setting of the background colors on the "SparkFun 20x4 SerLCD - Black on RGB 3.3V LCD-14074" without it posting a "you've set the background to x%" message to the screen.

Is there a way to suppress all status messages generated in response to configuration changes (setting number of characters/lines, colors, etc...)?

Does this require tweaking the sketch run on Serial LCD?
