Joy-IT Explorer 700 OLED SPI

[Mark0Mi]

Hi I have a PI with the Explorer 700 HAT from Joy-IT The display is the OLED 128x64 SD1306 but unfortunately it seems not to use I2C -> instead it uses SPI (and it is fixed wired on the Explorer700)

Product: https://joy-it.net/en/products/RB-Explorer700 Code examples: https://joy-it.net/files/files/Produkte/RB-Explorer700/Explorer-700%20Beispielcodes.zip in the folder OLED there is the code SSD1306.py to address the display and three sample codes for displaying text.

Can you add support for addressing OLED displays over SPI instead of I2C? or guide me how to do this? thanks!

How specifically is it accessed by the Pi (i.e. hardware SPI, software SPI, software device, pins)?

[Mark0Mi]

SSD1306.py.txt dispchar.py.txt I have attached the two files to get the display to work as far as I understood it it uses the spidev with hardware SPI (from dispchar.py)

Raspberry Pi pin configuration:

RST = 19

Note the following are only used with SPI:

DC = 16 bus = 0 device = 0 disp = SSD1306.SSD1306(RST, DC, SPI.SpiDev(bus,device))

the SSD1306 class is defined in the second file SSD1306.py

I just pushed a commit (untested) that adds the ability to select the LCD interface and adds the SPI interface for SSD1306 LCDs. If you're feeling brave and want to upgrade to master, you can test the new code, otherwise you'll have to wait until the next release.

I did the test - unfortunately it does not work. deamon log:

after I click deactivate

Error: Could not deactivate LCD controller with ID b51387b7-ee89-4062-9433-675a9b65d5bf, it's not active.
after I click activate it seems it gets activated but in deamon log the following shows up:

is there any other log you might need? BR marko

[kizniche]

No, the daemon log is where all the exceptions should be going. I just pushed a fix. You can upgrade to master and test again.

[Mark0Mi]

display works fine ;-) thank you very much!

one minor thing - after booting it shows line1: mycodo 8.5.8 line2: start 128x64 OLED (SD: and then after 30seconds (first refresh I guess) the configured sensor values

if deactivate is pressed same message with stop in line 2: (it should go blank shouldn't it?) if activated again I have to wait 30 seconds for the refresh but that's ok..

many thank for your very quick fix! BR marko

[kizniche]

That is the expected behavior.

hi after running now on 8.7.1 finally - my display is not working anymore can you check it?

Was there an event that caused your display to stop working? No LCD code has changed in mycodo since it was confirmed to work.

[Mark0Mi]

I switched back to the previous version apt-get update and upgrade then the mycodo upgrade to the latest 8.7.1 -> dashboards still not working... I switched then back to beginning of August (backup restore). From there I had the issue with the gateway timeout which I fixed by installing bcrypt==3.1.4 (you might remember I started from beginning with the desktop version of rasp. and there was an issue where the webserver would not start) then I have resetted all the dashboards and did the upgrade - since then I think the display is not working. Not sure what is causing this.. I did a switchback right before the upgrade but the display stays dark.. The command line file still works where I get the display to print something (the files I added in the beginning) Do you have any other idea how to get it back to work?

[kizniche]

Since the Adafruit_Python_SSD1306 is deprecated, I'm inclined to convert the module to using the Adafruit_CircuitPython_SSD1306 library. I declined to use the CircuitPython libraries in the past because of the difficulty with working with multiple I2C buses, a problem I've since overcome with the use of Adafruit_Python_Extended_Bus.

[kizniche]

I switched back to the previous version...

This is hard to follow. When you pasted the most recent error traceback, were you running the latest release?

[Mark0Mi]

I'm now on the latest version (but I know switching back does not get the display back - for whatever reason) to check if the display is damaged I ran the python scripts supplied by the vendor - and then the display works while running these scripts but mycodo does not initialize the display properly

[kizniche]

Can you test the circuitpython library? You will need to remove the current library because it has the exact same name as the new library. Uninstall with ~/Mycodo/env/bin/pip uninstall adafruit-python-ssd1306 (it may be Adafruit_SSD1306, so try both). Then, install the new library: ~/Mycodo/env/bin/pip install adafruit-circuitpython-ssd1306 then edit the pins, below, and execute the following code from the virtualenv with ~/Mycodo/env/bin/python ~/test_lcd.py

import adafruit_ssd1306
import board
import busio
import digitalio

spi = busio.SPI(board.SCK, MOSI=board.MOSI)
dc_pin = digitalio.DigitalInOut(board.D3)
reset_pin = digitalio.DigitalInOut(board.D4)
cs_pin = digitalio.DigitalInOut(board.D5)
disp = adafruit_ssd1306.SSD1306_SPI(128, 32, spi, dc_pin, reset_pin, cs_pin)

disp.fill(0)
disp.show()

image = Image.new('1', (disp.width, disp.height))
draw = ImageDraw.Draw(image)
draw.rectangle((0, 0, disp.width, disp.height), outline=0, fill=0)
draw.text((x, top), "TEST LINE", font=font, fill=255)
disp.image(image)
disp.display()

[Mark0Mi]

yes I can - I had to change the code a little please review if this is ok -> TEST LINE is shown on the display after executing this code

import adafruit_ssd1306 import board import busio import digitalio

from PIL import Image from PIL import ImageDraw from PIL import ImageFont

spi = busio.SPI(board.SCK, MOSI=board.MOSI) dc_pin = digitalio.DigitalInOut(board.D16) reset_pin = None cs_pin = digitalio.DigitalInOut(board.CE0) disp = adafruit_ssd1306.SSD1306_SPI(128, 32, spi, dc_pin, reset_pin, cs_pin)

disp.fill(0) disp.show()

image = Image.new('1', (disp.width, disp.height)) draw = ImageDraw.Draw(image) padding = 1 top = padding x = padding font = ImageFont.load_default() draw.rectangle((0, 0, disp.width, disp.height), outline=0, fill=0) draw.text((x, top), "TEST LINE", font=font, fill=255) disp.image(image) disp.show()

disp.display()

Ah, sorry I missed a few variables. Now I need to figure out how to do a switcheroo with user libraries, considering they're named the same (thanks, Adafruit).

[Mark0Mi]

no worries - one question why did my display stop working in mycodo? do you have any glue about that?

[kizniche]

No, like I said, none of the LCD code changed in Mycodo. So, either you have a filesystem issue of some kind (e.g. corrup files), or a library updated and broke something. The fact you didn't have Adafruit_BBIO is indicative of a filesystem issue because it is required for the LCD to operate, and you say your LCD was operating previously.

[Mark0Mi]

just a short update I did a complete re-install and now it is working again..
