I am a relative newcomer to programming with Arduino and I like it. I have just struggled through but found success at last interfacing a 1602 16 x 2 LCD display with an Uctronics UC-145 i2C controller.
The table shows the pin designations for my LCD on top and the UC-146 i2C pinouts on the second line.
| LCD # | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | | - | - | - | - | - | - | - | - | - | - | - | - | - | - | - | - | - | | | VSS | VDD | VO | RS | RW | E | DB0 | DB1 | DB2 | DB3 | DB4 | DB5 | DB6 | DB7 | BL1 | BL2 | | 2iC | VSS | VDD | VO | RS | RW | E | Do | D1 | D2 | Dw | D4 | D5 | D6 | D7 | A | K |
Using FMPartida's newest LiquidCrystal library and the following construct information I got the display to work properly: lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE)
Am I supposed to be able to tell from the pinout table which pin controls the backlight on my lcd?
Seeking to learn.
