Raspberry Pi Pico using MicroPython - Tutorial #4: Interfacing an OLED Display

The Raspberry Pi Pico is a new flexible microcontroller board from Raspberry Pi. It is a tiny, fast, and versatile board built using RP2040, a brand new microcontroller chip designed by Raspberry Pi.

In this video, we explain how to interface an OLED display with the Pico using an I2C interface. We also display data read from a potentiometer and a counter which increments every time you press a button. The IDE used is Thonny.

Protect this man! Have been trying to get it working. I found out that it is using sh1106 but no one seemed to show me where to download the library and how to send it to the raspberry pi. Thank you a lot buddy.

These Raspberry Pi Pico series have been so helpful 💯🙏

Clear, thorough, good stuff. But even better if you zoom in to the coding window - text is hard to read. Thanks.

Thonny gets stuck when creating the oled object. When aborting with crtl D or pressing stop I get into an error loop (Unable to connect to COM6: could not open port
'COM6': PermissionError (13,
'Permission denied', None, 5) )
I have to pull the cable to stop it.
I thought it might be a windows problem but on linux, I get a similar error.
Any help would be super helpfull🙏🏻

My Pico detect the i2c device, but when I run the code nothing shows on the screen. have tried 4 4 different SH1106 OLED modules now and not one of them will display anything???

can i use the same code to connect with PIC W ?

Hey man, have you done this on a display with user control like buttons or touchscreen ?
