Hello.
I made a python lib for the MCP 23017 i hope you will find it usefull , i am not a good programmer but i hope it does the job. feel free to give me pointers.

@crispyoz thankssss , I appreciate the comment

@Lazar-Demin it works perfectly

Hello , i know this topic was discussed before but the links are broken.
i have a .netcore c# app made in visual studio i want to cross compile it to run onion omega 2+.
Is it even possible?
if yes HOWWWWWWWWWWW
Thanks

@Jackdaw2 HEY
i am noob and i have no idea how to do all this. do you have some free time to chat on how to solve my problem?
i have a made a program with c# in visual studio on my windows10 machine. i want to know how i can run it or re code it on my omega 2+. is it even possible? thank you

did you run the python installation command and specified the python3.7?
i never tried but try this
opkg update
opkg install python3.7
and let us know if it works

@Nate i just gave up and got a usb to serial converter and i use serial communication , no lag . but the omega needs to be connected to my pc at all times , well at least i can prototype with out headache .
i will look into the antenna thing . thanks for the info

@Lazar-Demin it works perfectly

@crispyoz it did work , and no idea why . it even show the access point ............

"before the factory reset the access point was broken "

damn my mind is toasted ......... been debugging for hours ,...
yeeey

@crispyoz so much fun....................
the omega used to work fine.
now the led will blink and shut down .
putty will stop too
my putty setting are just the com port and the datta speed set to 115200
i have no eithernet doc so i cant run the web recovery mode.
i am lost here ........ its not even my board. i am borrowing it .

i had my omega IP show as omega-0000 after modding the etc/config/wirless file.
i only changed the channel to 1 instead of auto but it broke.
so i run factory reset command using USB to serial converter .
when i power it , the omega led will blink for a minut then i again get the omega-0000 after that it will stop working .

i copied the msg i get from the serial interface using putty and i included it below . please have a look at it and tell me if this is fixable and if you can guide me throw it .
note: i dont have a doc .
my power supply is . 3.3v 1.2 A
i did a voltage divider to divide the 5 v on the USB to 3v so i dont burn the omega.
