DFR0154 I2C/TWI LCD2004 module -- change SDA and SCL assignments
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
I am using an Arduino Uno R3 and need all six analog pins to monitor servo movements. Therefore using A4 for SDA and A5 for SCL for the LCD display is troublesome.
I have tried to use I2C software alternatives (SoftwareIC3 and SoftwareWire), but it does not seem that LiquidCrystal_I2C library honors the SDA/SCL reassignments since it persists in using A4 and A5.
How can I change SDA to D3 and SCL to D2 in my code, or do I have to modify the LCD library? If so, how?
Blessings,
