Mez, I can look at doing that. The reason for the arrow was to limit the space needed so that the font could remain as big as possible. If we are able to figure a way to do the numbers so that its readable, we'll post the information here.

Thanks for the suggestion. - Mark

Mark - Thanks for the quick reply. I look forward to hearing what you can come up with. Your work is greatly appreciated. 

Mez, I was able to play with this a bit and it looks doable. It should be in the next release. It will be setup in such a way as the builder can choose between displaying the wind direction using an Arrow or with numbers in degrees from the web interface under 'Display Options'.

Thank you for the suggestion. - Mark

Looking forward to having that in the next version. I am impressed with your code. Is there any chance I can see the changes you made. I would love to try it out. I am looking to see if the LCD ro OLED is better for me. Let me know and thanks again!

Around Line 302, replace this function with the one there (or make the changes);

def oledcenter(txt, ch, font, wndir=0, dim=dimswitch, onoff = 0, pause = 0): #Center text vertically and horizontally
    tca_select(ch) #Select the display to write to
    oleddim(dim) #Set brightness, 0 = Full bright, 1 = medium bright, 2 = low brightdef oledcenter(txt): #Center text vertically and horizontally
    draw.rectangle((0, 0, width-1, height-1), outline=border, fill=backcolor) #blank the display
    x1, y1, x2, y2 = 0, 0, width, height #create boundaries of display

    if wndir == "" or txt == '\n' or 'Updated' in txt or 'Calm' in txt: #Setup and print wind direction arrow
        pass #don't print any arrow in certain conditions

    elif wind_numorarrow == 0: #draw wind direction using arrows
        draw.text((96, 37), wndir, font=arrows, fill=fontcolor) #lower right of oled

    else: #draw wind direction using numbers
        txt = txt + ' @' + str(dir) + chr(176) #chr(176) = degree symbol

    w, h = draw.textsize(txt, font=font) #get textsize of what is to be displayed
    x = (x2 - x1 - w)/2 + x1 #calculate center for text
    y = (y2 - y1 - h)/2 + y1 - offset

    draw.text((x, y), txt, align='center', font=font, fill=fontcolor) #Draw the text to buffer

    invertoled(onoff) #invert display if set
    disp.image(image) #Display image
    disp.display() #display text in buffer
    time.sleep(pause) #pause long enough to be read

Around Line 121 - add this variable set to '1';

wind_numorarrow = 1        #0 = Display Wind direction using arrows, 1 = Display wind direction using numbers.

Around Line 1493 - remove the space in front of ' kts';

#add kts to the end of the wind speed if present
if isinstance(wnd, int):
    val = val + "kts"

Make these changes and it should work. Make a backup of metar-display-v31.py in case things go bad. You can set the variable above to '0' if you want to go back to arrows for the wind direction. Let us know how it works. Good luck. - Mark

So I was trying to flip the direction and speed so it display 110@10kts, but every change I make is erroring it out. I was wondering if you could take a quick look.

This isn't very elegant but it will work.

ap, wndsp = txt.split('\n')
txt = ap + '\n' + str(dir) + chr(176) + '@' + wndsp

It deconstructs the 'txt' message and then re-arranges the elements into the format order you would like. Let us know if this works for you. - Mark

Did you place this in the same place in the function above? When I do I am only getting the wind speed.

Yes, just substitute the first code snippet for the 2nd code snippet below. I tried it and it works well.

else: #draw wind direction using numbers
    txt = txt + ' @' + str(dir) + chr(176) #chr(176) = degree symbol


else: #draw wind direction using numbers
    ap, wndsp = txt.split('\n')
    txt = ap + '\n' + str(dir) + chr(176) + '@' + wndsp

I saw what I did and that worked. I appreciate the quick responses. I think it is great to have the option. I will get some vid once this is done. 

Since we can set a user defined wind speed so the lights blink, would it be possible for the OLED's to display the wind data for that airport? Maybe from highest speed to lowest in order?

Or is it just a set list of airports?

Hi Ron,

If I understand your question correctly, yes you can do that. The first 4 settings under the 'LCD And OLED Display Settings' should accommodate that. Set the first setting to the Max number of airports to display and be sure that the 4th setting is set to 'Yes'. Keep in mind that the order in which the airports are displayed is sorted by their wind speeds. So the highest wind speed airport will be displayed first followed by the second highest and so forth.

If you want all wind speeds, regardless if they are blinking or not then set the 4th setting to 'No' and then it will cycle through the number of airports you specify in the first setting regardless if they are higher than the high wind setting in 'Basic Settings'.

You can also limit which airports are displayed by filling out the list in the 3rd setting. No other airport will be displayed, only those in the list.

If I didn't quite understand the question, let me know. - Mark
