Thank you to GolfCharlie and Claude Code for fixing the code to work with the newly changed FAA API! They have saved a lot of time. A new image has been created and will be uploaded today and available later tonight. If you don't want or need the image, you can visit https://github.com/markyharris/livesectional and incorporate the changes into your board now.

There has been another change to the FAA API which has again broke the map. We are currently working on this. Check back for fix. If you have the fix please post it. - Mark

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
