      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 StartedandIntroduction 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

      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

      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

      <p>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
