Wirelings / .42" OLED usage with Arduino UNO?
« on: May 04, 2020, 11:56:22 PM »
Hi there.
I have the 0.42" display and an UNO.
I have downloaded the examples and wired the display as:
J1.1 to GND on the Arduino board
J1.2 to 3.3 on the Arduino board
J1.3 to A5 on the Arduino board
J1.4 to A4 on the Arduino board
J1.5 to A0 on the Arduino board
BTW, to make these connections, I disconnected one end of the 5 pin Wireling cable and soldered on pins that fit correctly into the UNO sockets.
The result of running the example code from 0.42-Screen-Text-Example is a screen with a bunch of random white bits.
Perhaps I'm connecting something wrong?
Can anyone please comment if they see something I'm doing wrong.
Thank you!
