I2C LCD Library... Help!
Posted: Tue Mar 01, 2016 1:00 am
I'm trying to get a 20x4 LCD with i2c packpack to work. I'm running the pyb_i2c_lcd_test.py. It prints to the console and if I pull SCI or SDA I get a OSError: 5 suggesting that things are communicating. But the LCD does nothing. It works great on an arduino no problem. And yes there is a LLC inbetween.
The hardware:
LCD - https://www.adafruit.com/product/499
i2c Backpack - https://www.adafruit.com/products/292
I've been looking through all the data sheets. I'm guessing that there are some bytes out of sequence with what has to be sent to the LCD or backpack. But it's getting beyond what I know and I'm starting to pull my hair out.
Any help would be greatly appreciated
Cheers
