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
