Hello I hope you can understand my english I have a texas instruments tm4c123gxl with a SainSmart IIC/I2C/TWI Serial 2004 20x4 LCD Module. I will connect this Display over I²C. For the 5V Supply voltage i have use the VBus on the tm4c... For the SDA/SCL i have use the pin PA6 and PA7. Does it work like this? or need a Logic Level Converter - Bi-Directional for the SDA/SCL Line? from 3,3V to 5V. I have use a Pullup resistor for the Line SDA/SCL, how in the datasheet from the tm4c. And i have use this Code: #include <Wire.h> #include <LiquidCrystal
