I have tried every single tutorial and example that I can find to drive my 16x2 LCD with I2C connection but without success.
The problem must be related to something that I'm missing on RuneOS as none of the scripts I found was able to drive the LCD.
I must be missing something. Can someone help me?
A quick description of the Hardware:
- Adafruit "RGB backlight negative LCD 16x2 "
- Adafruit "I2C / SPI CHARACTER LCD BACKPACK"
- Raspberry 3
And a quick description of what I found so far:
- I2C and LCD should be ok cause they work with an Arduino
- The address (0x20) appears on i2cdetect so there's communication
- WiringPi should be also OK because I'm using it with on other GPIO ports
This night I'll start from a fresh image and I'll post a log of what I've done and what happened so far.
If someone have some sort of tutorial I'll be very glad to try it.
