IT FIXED IT

?

Get back to me after dinner - I'm done here for now.

schneel · February 7, 2021, 5:58pm

ok

UKHeliBob · February 7, 2021, 6:45pm

Is there any chance of you posting your full sketch as it is now and the full error messages or shall we carry on guessing ?

anon73444976 · February 7, 2021, 7:51pm

I guess it was that urgent after all.

Goodnight.

dunno why i was allowed t post it kept saying i passed the 9000char

So, not a programming error

Which Arduino board are you using ?
Which board have you got selected in the IDE ?

alto777 · February 7, 2021, 10:53pm

I hate that

avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x9a

which happens to me from time to time. Check the board type and port. Try a different USB port. Should not be the cable, which worked just yesterday, but what the hey, try another.

Reset the USB sub-system. (I only know to reboot my machine.)

I’ll go weeks or months with no USB trouble at all, then suffer all sorts of problems for days, I have quite a few Arduino-like things I plug and unplug.

Pro tip: keep a Terminal window open handy and enter the command line “killall avrdude” when this error starts and you will cut short the agony of watching it try and fail ten times.

That’s on MacOS, perhaps a Windows and a Linux guy can share an equivalent.

arduino pro mini atmega 328 but really dont knowwether 5 or 3 volts

tried both in ide

TheMemberFormerlyKnownAsAWOL:
Don't use '10', use 'A'.

well

i tried again and thank god i was able to upload/test basic blinking sketch

but uploading the main sketch (that the whole post was originally about) after changing '10' to 'A'

failed giving error

What a shame we can't see the code.

dunno what u mean :o :o

simpler pls

i tried using the simulator app an removed a switch so there wasnt a '10' to replace with A

The first warning is about your function menu(), this function is missing a return statement at the end.

The 3 other warnings are from that "Button" library that you are using, a variable should be set to type unsigned long

As said, these are just warning, and your code was compiled successfully, but for some reason it couldn't be uploaded to the board. It's not related to the code. Try install drivers for the usb-serial chip that is on your board, or try another usb cable, or search google for this "not in sync: resp=0x9a" error
