wemos lolin esp32 oled ssd1306

[exider]

Hi all,

Just got a new chinese clone of lolin wemos 32 with integrated oled ssd1306 display.
The board is flashed with the latest firmware (esp32-20170729-v1.9.1-391-g06168c92.bin ), and i am trying to work out an examle taken from this web page :
http://www.instructables.com/id/MicroPy ... ated-SSD1/

If i try to import the ssd1306 module i get an error 1st time ,but 2nd time it imports it correctly with no errors(i have tried importing all libraries i could have found.
for exaple this one .. https://github.com/adafruit/Adafruit_Ci ... /tag/1.0.2
if iscan i2c bus , ican see the display

>>>i2c = machine.I2C(scl=machine.Pin(4), sda=machine.Pin(5))
>>>i2c.scan()
[60]
Also the display works with arduino samples.

The problem comes when i try to use it:

>>>oled = ssd1306.SSD1306_I2C(128, 64, i2c) # --> at this point i get an error saying:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'SSD1306_I2C'
>>>

I would appreciate any help you guys can provide!

Thanks

What is the error you get when you try to import it?

Why are you using an Adafruit library? I'd use the official MicroPython one: drivers/display/ssd1306.py. I haven't tested it on ESP32 but it works on the Pyboard and ESP8266.

Hi deshipu, thank you for asking. Your question helped me to figure out the problem. The indentation was messed up on the last line. Now I have to figure out how did that happen or which IDE did that as I didn't edit, just looked at the code and it obviously happened to all libraries I've tried. I am new to python, and as the code got imported second time I've tried, I tought the problem is somewhere else. Anyway, thank you guys for looking into this and help resolving the issue.
