I created a project using a 3.2" tft LCD screen and I've got a few questions.
Is there any way to power down the screen? I'm thinking along the lines of a hard switch. There doesn't appear to be any way to do it programatically. I only need to use the screen occasionally but need to leave the Arduino running all of the time.
Is there an enclosure on the market that will hold a 3.2" tft lcd screen and Mega 2560?
Can I use a cable between the controller and LCD screen? This might be helpful when it comes to mounting it in an enclosure.
The project information is here: Solar Load Control - Home Automation - Arduino Forum
It monitors my off-grid solar system and turns the AC when there's enough juice then off when the Sun goes down.
Also of note;
The project contains a few functions that I created to manage touch screen buttons. One function is called to create a button based on arguments. The size of the button is calculated based on the length of the label. The bounds of the button and the function to execute when pressed are stored in an array. When the screen is pressed, the array is scanned to look for a button in that screen space. If found, it executes a function which is called by number.
