Hi,
I bought the LCD Shield Kit w/ 16x2 Character Display shield.
Is it possible to display custom characters on the display?
Kind regards
Koen

Hi,
I have found the solution.
Below you can find a small example
Kind regards

Code: Select all
#include <Wire.h>
#include <Adafruit_MCP23017.h>
#include <Adafruit_RGBLCDShield.h>
byte smiley[8] = {
B00000,
B10001,
B00000,
B00000,
B10001,
B01110,
B00000,
};
Adafruit_RGBLCDShield lcd = Adafruit_RGBLCDShield();
// Pin definitions
const byte
RTC_GND_PIN = A2, //I use A2 for GND and A3 for VCC to power the I2C equipment
RTC_VCC_PIN = A3;
void setup(){
pinMode(RTC_GND_PIN, OUTPUT);
pinMode(RTC_VCC_PIN, OUTPUT);
digitalWrite(RTC_GND_PIN,LOW);
digitalWrite(RTC_VCC_PIN,HIGH);
lcd.createChar(0, smiley);
lcd.begin(16, 2);
lcd.write(0);
}
void loop() {}

Re: Create custom charactors on LCD Shield Kit w/ 16x2 Chara
I know this is an old post, but the reply for Le-bo2d9 did not work for me. Instead of a smiley I got pixel garbage.
After a little experimentation I found that the problem goes away if you put lcd.begin above lcd.createChar.
I did not have to call any pinMode or digitalWrite functions and did not have to setup any pin definitions.
This seems like an easier fix, so I thought I would post...
