I2C LCD DISPLAY DRIVER (i2c_lcd_2884.zip)
- I modified the library according to what i was thinking correct but i can't get it working properly.
- In this case the fc-113 iic/i2c serial interface adapter module for 1602 or 2004 lcd display.
- However, the examples fo how to drive i2c with ssd 1306 is very rare, and they run on raspbian not windows.
- The first and most important thing to note is that some of the displays may have the gnd and vcc power pins swapped around.
- So if you define an array of less than 26 ones, strange characters will supplement the shortage, which is mess code then.
- As we all know, though lcd and some other displays greatly enrich the man-machine interaction, they share a common weakness.
