BeagleBone black wireless Cape


#1

Hello everyone, I’m wanting to develop an 7" LCD cape for BeagleBone Wireless and I will not use Touch.

Can anyone tell me if I need the eeprom IC that uses I2C?

Another question, to use this eeprom I would need to write the data manually or does the LCD driver do this?

Sorry for the basic doubts. Thanks!!

Your questions can go either way, it is really up to you.

Here’s my go-to reference for cape eeprom design : https://github.com/jbdatko/eeprom_tutorial/blob/master/eeprom.md

The eeprom is not strictly required, but does make driver management easier. You need to write the ID code into it yourself - the driver doesn’t do that, but might choose to store other driver-specific info.
