Hello, I have a lot of this lcd with RGB backlighting but in v1.0, I ordered 8 lcds in V2.0 LCD works well but no backlighting and I don't know why, when I plug in a v1. 0 on my project the backlight works fine, when I see the library it appears to be the same one I'm using with V1.0. Maybe there is a different library for V2.0 LCDs? Thank you for your reply !
JaneYu ok, I found the solution, I actually use the DFRobot_RGBLCD Lib, I downloaded the DFRobot_RGBLCD1602 lib here: https://github.com/DFRobot/... and I changed the RGB address to 0x2D with this command: DFRobot_RGBLCD1602 lcd(/*RGBAddr */0x2D,/*lcdCols*/16,/*lcdRows*/2); //16 characters and 2 show lines
Hello,
I have 4 DFR0464 i2c LCD screens, an Arduino MEGA2560 R3 and the DFR0165 I/O shield. I want to use two screens on the same arduino. A screen named LCD and a screen named LCD2.
I saw that there were two I2C addresses per screen (LCD and RGB) but I can't configure the addressing correctly for two screens, yet I took over the syntax of the constructor in the .h file
Could you tell me how to have two screens on an arduino mega?
JaneYu Hello, do you want all dots off after power on? If yes, I think the function clear() is suitable. Call it after the initialization.
（clear display, set cursor position to zero）
