It is pretty likely that Pico Thonny Python's error message " OSError: 5" is similar to Rpi Os's " OSError: Remote I/O error"Įrrno 121 usually occurs when running an I2C python program with the following situation:Ģ.1 The hardware wiring connection is bad, eg,Ģ.1.2 I2C frequency too high, over 400kHz,Ģ.1.3 I2C device, eg. Anyway, I used Tom's Hardware's short program and found it OK, though not stable. I also found I2C Bus 1 better than Bus 1. I need to make the the wiring short, not to load two or more devices. I found the 0.91" OLED a bit tricky to detect. How can Rpi Pico Micropython Talk To I2C LCD SSD1306? it wasnt until a few months after i took a break that i could solve the issue Many thanks to tlfong01 for helping me find the issue even if we couldlnt find the solution. I dont remember exactly the library that i looked up, but if asked, i can share the file. i can no longer use the module manager for the ssd1306 library, but i could just include one i found online. errno5 means that the pico couldnt see the oled on the i2c interface. It has been some time since i posted this question, but this is what i found. i googled "OSError 5" and the only solutions that i could find were to add a delay between the initiation and the first write to the i2c device. I honestly dont know what this is trying to say. When i try to run it i get the following message Traceback (most recent call last):įile "/lib/ssd1306.py", line 110, in _init_įile "/lib/ssd1306.py", line 36, in _init_įile "/lib/ssd1306.py", line 71, in init_displayįile "/lib/ssd1306.py", line 115, in write_cmd Ive basically copy and pasted from Tom's hardware from machine import Pin, I2C Im following Tom's Hardware tutorial here
