I2C OLED on DIY 2.4 TX

Hi,

I'm building diy 2.4 micro tx with e28 module. Everything works fine. I can bind, set everything from lua script until I hooked up oled module.

The oled module is working but after that seems the serial port is not working. It's like there's no connection to my remote whatsoever.

I also added rgb and from the rgb i know that my diy tx module is not making connection to the remote.

If I flash it again without -DUSE_OLED_I2C it's working normal again. What did I miss? How to fix it?

Thanks!

Start by comparing the build with and without -DUSE_OLED_I2C, then inspect the OLED module connection and the serial connection on the DIY 2.4 TX with the E28 module. Done means the OLED works while the serial port and remote connection remain functional.
