Question- I'm trying to compile and verify files under Windows 7 and 8 utilizing 1.8.14 and 1.8.15 (stand alone) with no luck whatsoever. I get errors when compiling and have not managed to figure this out. I can write the compiled file to the nano and it works till it gets to the section that sketch indicates isn't right.

What setups are people using to verify and compile? I'm going to try Windows 10 Pro at work tomorrow.

1) Tried Black Jack, also warning messages as well but related to maximum number of lamps.

2) Currently working on a Flash Gordon, attract mode is fine but there is a wizard mode in the game that is clearly broken and the warning messages reflect errors in compiling that section.

I'm going to try compiling on a Win10 machine at work this morning. I'm curious what other people are using to compile.

No luck under Win10 with installed or thumbdrive version.

Process of what I'm doing this morning.

1) Downloaded and installed 1.8.15 under Windows 10.
2) Downloaded FG2021.zip from github, unzipped to FG2021 folder.
3) Launched "C:\Program Files (x86)\Arduino\arduino.exe"
4) File-> Open -> FG2021.INO
5) Sketch -> Verify/Compile

Here is error list from Flash Gordon-

Sketch uses 26324 bytes (81%) of program storage space. Maximum is 32256 bytes.
Global variables use 1341 bytes (65%) of dynamic memory, leaving 707 bytes for local variables. Maximum is 2048 bytes.

Thank you for checking, been banging my head against the wall trying to figure out what I had been doing wrong. My first foray into Nano programming so far has not been smooth but I'll stick with it for a bit.

I had no problem compiling and verifying the Stars2020 code.

I'm considering trying to pickup this route and do code and wave trigger for Star Trek.
