Description


Done with tedious mono color backlight? This Grove enables you to set the color to whatever you like via the simple and concise Grove interface. It takes I2C as communication method with your microcontroller. So number of pins required for data exchange and backlight control shrinks from ~10 to 2, relieving IOs for other challenging tasks. 


Besides, Grove - LCD RGB Backlight supports user-defined characters. Want to get a love heart or some other foreign characters? Just take advantage of this feature and design it!


This product is a replacement of Grove - Serial LCD. If you are looking for primitive 16x2 LCD modules, we have green yellow backlight version and blue backlight version on sale also.



Features

  • Colorful RGB Backlight

  • Built-in English and Japanese fonts

  • I2C communication, uses only two IOs

  • Automatic power-on reset


For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.

The contrast is very poor on mine. I can barely read the text. It is plugged into a Wio Link, and has 2.5a of power. Can I adjust the contrast?

I had the same problem. The backlight was fine, but the contrast was so poor that I could only ready the characters if I tilted the display just right. What I determined was that the voltage being supplied to the display was too low. I was powering the display from a Nano, and powering the Nano off of USB. When I read the voltage going to the display on the 5V pin, it was only about 4.3V. When I powered the Nano via the VIN pin and thus it was able to put a full 5V out of the 5V pin, the display worked just fine.

Yes, This Grove need 5V, but the wio link/node just provide 3V. Thanks god you can see on 3V3. You need some hack for this, look this thread: http://www.seeed.cc/Grove-LCD-RGB-Backlight%3A-no-output-t-11260.html

I've found that contrast is low when powering from a 5V USB port off a computer. I hooked up a 12V 5A power supply to the 2.1mm barrel connector on a Mega Arduino, and wow - contrast is great! Yes, normally you probably don't need (or want) a 12V 5A power supply, but in my case I use it to power the Mega and a 5m (16.4 ft) RGB LED strip - which takes a far amount of amperage to drive the LEDs anyway. Give it more power and you will likely see improved contrast. I have a ton of other stuff attached to the Mega, and its all working well with the 12V 5A power supply...

what is the maximum number of different custom characters that can be displayed at one time? I'm trying to display 14 custom characters. But it appears to copy the last 8 characters created over the rest. So, it seems like the limit might be 8 characters. This issue could be my hobbyist level of programming skill.

I understand it can display 32 characters at once. I found my problem in the library. It can only hold 8 custom characters in memory at one time. void rgb_lcd::createChar(uint8_t location, uint8_t charmap[]) { location &= 0x7; // we only have 8 locations 0-7 ........ Thanks

Using a spare Arduino GPIO, is there a way to disable/enable the entire lcd module. The I2C address of the RGB controller conflicts with another device on my I2C bus. I would like to disable lcd module, change i2C address of conflicting device, enable lcd module, then proceed normally. Any suggestions?

Hi, You can enable one I2C device by setting the corresponding I2C address

Can we use this LCD with STM32L0 series controller

Hi there~ theoretically, you can. However we do not have the library for STM320, you may need to write the library yourself. Regards

The Wio Link API says that "you must jump VCC of Grove-LCD to 5V". How can I do this without backfeeding 5V into the Wio Link and frying it?

Would it be possible to integrate this LCD with PIC Microcontroller such as PIC16F877A? I see your serial library. I am not sure whether PIC microcontroller support it or not.

I would like to use it with a spark core. Do i need pull up resistor for i2c?

I think not, like Arduino, also no need pull up resistor.

Is there a schematic for this anywhere? I'm trying to use it with a Grove Shield on an ST Micro Nucleo board. I've got it hooked up to my scope and am watching the i2c bus. One of the questions is the address for the LCD and RGB driver are shifted in t

Replying to my own post but I solved my issue. To use this display with the ST Micro Cortex M series you set the GPIO's to Open Drain, and tie them through 10K pull up resistors to 5V. Then the display will respond correctly (the ST inputs are 5v toler
