@CAProjects, excellent job, that gps icons looks fantastic. Have managed to fix mine as well. If anyone is interested I can post my updates to the code.
I added the additional widgets next to settings.
@CAProjects: Where is the gps icon stored? Or is it drawn pixel by pixel from the code itself?
the image and gif location is /usr/share/pt-sys-oled/images after copying with terminal and using sudo you need to sudo chmod 666 filename.extension replacing filename with the filename and extension with what ever the image file extension is
@Luis the GPS image, well Gif i made myself
Thanks a lot for sharing this. From you previous post you mentioned that the GPS code you created will have to be redone completely. Is this because the code needs to follow the same template code? I noticed there is a template in usr/lib/pt-sys-oled.
There is a certain structure it has to follow
@pi-topMIKE @Luis @Supernovali I FINALLY DONE IT!!!
got GPS info running in the system menu 
sooooooo much starting and stopping pt-sys-oled.service 
and soooooooo much looking at the code wondering what I got wrong and why the service restarts itself when selecting the GPS page. BUT i finally got it working and it does update every second which is nice
The only information that is being displayed is from RMC NMEA sentence, Lat Lon and speed
1 thing with it is that it takes a second or 2 to change to the GPS, but only happens once, i dont know why, it just does, but going back to it after its perfectly fine

WHAT I DONE
I started modifying a copy of the WiFi Widget then scrapped it gave me the information to write my code
Step 0: Edit Menu.py to add an extra menu item
Step 1: config my GPS unit to ONLY show RMC NMEA data
uart.write(b'$PMTK314,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0*35\r\n')
Step 2: Config my GPS unit to a 1hz refresh
uart.write(b'$PMTK220,1000*1F\r\n')
Step 3: Install pynmea2 as sudo
Step 4: Get some sort of NMEA displaying on the screen as in my previous post
Step 5: get pynmea formatting
Step 6: get Lat, Lon, Speed displayed in the correct display format
Step 7: import common values to position the text
THE CODE
And here is the code i wrote to make all this happen ( no fancy icons or that just text) enjoy the mess
import serial, io, pynmea2
from components.widgets.common.functions import draw_text
from components.widgets.common.base_widgets import BaseSnapshot
from components.widgets.common.values import (
default_margin_x,
common_first_line_y,
common_second_line_y,
common_third_line_y,
)
class Hotspot(BaseSnapshot):
def __init__(self, width, height, mode, interval, **data):
super(Hotspot, self).__init__(width, height, interval, self.render)
self.uart = serial.Serial('/dev/ttyS0', 9600, timeout=5.0)
self.uart_read = io.TextIOWrapper(io.BufferedRWPair(self.uart, self.uart))
self.interval = 1
self.nmea_dict = {
'latitude' : "",
'longitude' : "",
'speed' : ""}
def render(self, draw, width, height):
line = self.uart_read.readline()
msg = pynmea2.parse(line)
if msg.sentence_type == 'RMC':
pole = 'N' if float(msg.latitude) > 0 else 'S'
lat = f"***{pole} %02dm %04.2fs" % (msg.latitude_minutes, msg.latitude_seconds)
draw_text(draw, xy=(default_margin_x,common_first_line_y), text=str(lat))
pole = 'E' if float(msg.longitude) > 0 else 'W'
lon = str(abs(int('%02d' % (msg.longitude)))).zfill(3)
lon = f"***{pole} %02dm %04.2fs" % (msg.longitude_minutes, msg.longitude_seconds)
draw_text(draw, xy=(default_margin_x,common_second_line_y), text=str(lon))
speed = f'{round((float(msg.spd_over_grnd) * 1.150779448),1)} MPH'
draw_text(draw, xy=(default_margin_x,common_third_line_y), text=str(speed))
BASE STARTING POINT
this is all i took from the WiFi widget to start my code
from components.widgets.common.functions import draw_text
from components.widgets.common.base_widgets import BaseSnapshot
from components.widgets.common.values import (
default_margin_x,
common_first_line_y,
common_second_line_y,
common_third_line_y,
)
class Hotspot(BaseSnapshot):
def __init__(self, width, height, mode, interval, **data):
super(Hotspot, self).__init__(width, height, interval, self.render)
def render(self, draw, width, height):
draw_text(draw, xy=(default_margin_x,common_first_line_y), text='Hello pi-top[4]')
Conclusion
I look forward to an easier way to add to the system menu, any 3rd party modules, install them wiht sudo pip3, whats next with the system menu for me? NOTHING, was really frustating to code, any little error will cause the menu to fail starting (no reboot required, just disable service, stop it enable it and start it). VSCode cannot be started via sudo so saving every time requires typing in password.
Its done, a proof of concept that works
@CAProjects: Brilliant! Well done and again thanks for your hardwork and sharing this with us. I will definitely be adding this to my sub-menu😊. Will also try to have the logo for the gps you created, it’s simply to nice to leave it out.
With regards to the pt-sys-oled service, I feel your pain😂
Did you implement the other widgets that were there (disk, uptime, clock, etc)?
Have a great weekend,
Luis
Awe yeah!!! I love it. I’m going to start tinkering a bit here and there too. So much going on right now I havent been sleeping good but I’ll probably get to it tomorrow and play with it too
No I did not as I did not focus on them.
I am thinking of doing a proper knowledge base up on what functions you can import and how to use them and how to make widgets so that we have some documentation on how to do it all.
@Luis the disk, uptime, etc does need an overhaul to the design as they are rather basic so when i know more I may also look into doing that too.
I for got tp mention that another annoyance i had was that i could not use VSCode with Remote SSH when working all this out, and that is because i could not save the work due to needing to enter a password all the time so everything had to be done on the pi-top itself 
@CAProjects nice one!!
For the VSCode issue, can you just use:
sudo chmod -R 777 /path/to/directory
to give full access to edits? Probably safer to store them in the home directory and copy them over using sudo when done though…
@CAProjects: I think a knowledge base would be fantastic, this would definitely help a lot, especially for people like me who are not very versed in programming😂. I did come across this, which gives out some details:
https://pi-top-pi-top-python-sdk.readthedocs-hosted.com/en/stable/api_pitop_device.html
Don’t know if you seen it before.
Yeah, the uptime, disk are pretty basic but they do the work😂. Would be nice if we can get a widget working for vcgencmd measure_temp and vcgencmd get_config arm_freq to output the info on the miniscreen. For me at least these would be very useful since I am running the RPI overclocked.
measure_temp and get_config arm_freq is actually easy I have the code for that as I made a system temp script for cooling testing
CPU Temperature
str(round(float(open('/sys/class/thermal/thermal_zone0/temp').read()) / 1000,2))+'°C'
CPU Clock Speed
str(int(int(str(os.popen('vcgencmd measure_clock arm').readline().strip('frequency(48)=')).strip())/1000000))+' MHz'
Both are 1 liners that gets the values and strips everything and formats it in 1 go. That’s my old way of doing it, would do it as an fstring now
This is what got me tinkering with the oled in the first place. I was planning on adjusting the looks of the CPU monitor and add temp and speed to it. Just been so busy with everything else, I havent return to it yet.
@Supernovali: If you get this running please let us know. I am also curious about the temp and speed displays widget😉. Thanks
Wowww🤗, yess pleaseee😂. Can I also keep disk usage, clock, etc and use this also?
this is a seperate widget so you can add it as a new one, still working out some kinks tho
Will the GPS code work in the same way? That would be awesome to have all these extra widgets at a push of a button. An sftp start/stop widget would also be something really nice.
Thanks again for everything 
GPS code was done, its at the top of this thread. Was how i cracked making a widget

Sorry forgot about the post, thanks for reminding me. Can’t wait to play with this later today😁
