Hi Guys,

I designed a PCB for the Live Sectional so there is no need for all the wild wiring anymore 🙂

I have one problem, the OLED doesn't work right, if I test it with my own python code it works but with the live sectional image I only get "snow" (see pictures attached)

Can anyone help me with that? I also have 3 more PCBs for anyone who wants to test it as well. 

Thanks!

That is very cool! Great job. I'm jealous.

Not sure why you are getting snow. Post your test code and I'll compare it to the LS code to see what might be different.

BTW: I'd love to buy one of your boards to play with if you still have one available. Let me know. - Mark

@markyharris I can send you one for free. You did all the work with the coding 🙂

PM me your address.

Here is the code I used for testing. 

import time
import subprocess
 
from board import SCL, SDA
import busio
from PIL import Image, ImageDraw, ImageFont
import adafruit_ssd1306
import board
import adafruit_tca9548a
 
import board
import digitalio
 
 
i2c = busio.I2C(board.SCL, board.SDA)
 
tca = adafruit_tca9548a.TCA9548A(i2c)
 
disp = {}
displays = 1
 
 
co = 0
while (co < displays):
    disp[co] = adafruit_ssd1306.SSD1306_I2C(128, 64, tca[co])
    co += 1
    
 
co = 0
 
while (co < displays):
    # Clear display.
    disp[co].fill(0)
    disp[co].show()
    co += 1
 
width = 128
height = 64
image = Image.new("1", (width, height))
 
# Get drawing object to draw on image.
draw = ImageDraw.Draw(image)
 
 
padding = -2
top = padding
bottom = height - padding
# Move left to right keeping track of the current x position for drawing shapes.
x = 0
 
font = ImageFont.load_default()
 
co = 0
 
while (co < displays):
    draw.rectangle((0, 0, width, height), outline=0, fill=0)
    draw.text((x, top + 0), "Display " + str(co), font=font, fill=255)
    disp[co].image(image)
    disp[co].show()
    time.sleep(0.1)
    co += 1
