RGB LCD with USB backpack and LCD Smartie

[aeary]

Hello All,

I am new to this and doing a simple project for work. I purchased a USB + Serial Backpack Kit with 16x2 RGB backlight positive LCD from Adafruit. I am using LCD Smartie right now to control it and its awesome, except that I am unable to change RGB colors. When I use realterm to send the hex code (0x4E 0xD0 255 0 0) I am able to change color to red so I know the RGB LCD and backpack are working. Now I just need to make it work in LCD Smartie. Any assistance would be GREATLY appreciated!

Have you tried using the sequence $Chr(78)$Chr(208)$Chr(255)$Chr(0)$Chr(0)

I don't know if this will definately work but in theory......

What driver are you using in LCDSmartie?

Hi !

So I finally found a solution to change the color of the LCD ! With this line : $Chr(254)$Chr(208)$Chr(255)$Chr(1)$Chr(1) (The three last Chr are for the RGB colors that you can change), I have to put in on a different "screen" in LCDSmartie because if I put some text after it will do some garbage texts after.

So if you want to make the color change you have to send multiple times with differents numbers for the 3 last parameters (1-255) or make a program that does it :p but I'm not good at programming :p
