2) What can you do to help?
3) display.begin(SSD1306_SWITCHCAPVCC, 0x78); // initialize with the I2C addr 0x3D (for the 128x64)
4) Nahh!!! Provide something that will scream into the serial port if the address is wrong (no ACK).
5) Come on, this is basic debug stuff woman :)
Else, was able to get the library and examples installed without much ada from links here :
Still struggling to get a peep..
Scary one - with a 21k code size, it takes forever for the program ..
Anyhow, watching this meister (Julian Ilet), I realize I don't have the I2C pullup resistors. So, I add those, and,... not a peep :)
But, sticking with the video - eventually brings a smile to my face. All you have to do is change 0x3D to 0x3C in their code. Never mind that the actual PCB has silkscreen writing saying addres 0x7A and 0x78 and a resistor on the 0x78 side :) So cute, the Chinese and Americans combine to chop up the world.. Did I need the I2C pullup resistors? Nope :) Shame!!! Why do they leave us guessing like this? Anyhows, all's well that ends well, onto Mbientlab when it gets here.. and then, Jül :)
