ESP32 MicroPython OLED Display

OLED display of resolution 128 x 64 , 0.96 in, blue ,I2C protocol is iused in this demo with ESP32 Micropython.
OLED is built on SSD1306 IC , and a ssd1306.py library is available for easy interface.

One of the very best for MP and OLED thank you my friend Saravanan!

[@ChandrashekarBabu]

Awesome explanation with very useful info - saved me a lot of time. Thanks!

[@marinehm]

Thank you sir, this is just what I was looking for today.

[@electronic7979]

Useful video 👍

Grande tutorial. 😊👌

Thank you

Very nice. 🌅 Thank you.

As I was using a PyBoard instead of an esp32 I was worried these instructions wouldn't work for me, but with minor modifications it worked a dream. This video is awesome!

[@maheswarkk1034]

Can you please tell me how you modified it? Thanks!

@@maheswarkk1034 Hopefully you can extract the code you need from this:
'''
Step 1: Get the current system time
Step 2: Write out the current time to the microcontrollers's rtc object
Step 3: Synchronize the rtc object with the ds3231 module
Step 4: Within a loop write out the ds3231 get_time value to an oled display
Step 5: For now print out the hours, minutes and seconds
Step 6: Within the loop calculate days until retirement

@@wrightkevin9000 Wow! Thanks so much! Did not expect you to reply because its been a year. Was looking for this. There is not a lot of tutorials explaining things about the pyboard.

[@PeterEvans-english-adventure]

This is great. I can work well with the I2C bus but I am having trouble with getting SPI to work. Do you know where I could get such a video as this but for SPI in micropython on an ESP32 WROOM

[@photobusta]

Trying to program an epaper, with micro python esp32, do you have a tutorial for that?

[@rutwiktaday8717]

Sir is this the method where we can save any library in micropython?

[@ReidarVik]

Sir. Can I use this method with a micro:bit?

AttributeError: 'SSD1306_I2C' object has no attribute 'fill_rect'

[@galangmangun4024]

I have a problem, when i run it, the Thonny Shell said " Warning: I2C(-1, ...) is deprecated, use SoftI2C(...) instead" and when use SoftI2C, in the shell "NameError: name 'SoftI2C' isn't defined". Can you help me to fix it. I will be happy if you can help me

[@karthiknivedhan8622]

you must use
from machine import SoftI2C
