Is there a file size limit for .ino files?

A year or two ago I built a project for scrolling text messages on 4 connected MAX7219 modules. It worked perfectly. I've been thinking of trying a few new ideas and hoped to avoid damaging my Arduino, or other components/modules by simulating my changes first.
I replicated the circuit easy enough, compiled and uploaded my code without issues. No errors were displayed, but the simulator didn't show any activity on the MAX7219's. I double checked everything, wiring, code, etc. Most of the code appears at the start/top of the file, but the actual scrolling routines are at the bottom, the last few lines. The thing that really stuck out to me was the code color went from black to red. I couldn't find anything, anywhere, as to what caused the color change. This change to red, happened in line 281, of 1166. If any one knows why, I'd appreciate your reply.

As far as I know there is no size limit for .ino files.

About the circuit not working, can you provide circuit and .ino files?

I tried but keep seeing the error

Create a zip file with everything.

Thanks!

Please correct line 23, I left out a semicolon...

const int msgCount = 15; // number of messages to display

There are some errors in your code:

- Error creating LedControl at line 36.
- Error reading ADC at line 1090.

Additionally:
Error in line 281:

Code:


B00000000,   //*


The /* characters are the beginning of a multiline comment. Anything below 281 lines will be a comment. I recommend putting the * character in quotation marks: "*"

In line 19 there is a link to the missing file "LedControl.h" in the archive

Sorry... I edited my last reply, you probably are unaware.
Please change that and try again.

There are still some errors in your code:

- Error creating LedControl at line 36 (or connection error in the circuit).
- Error reading ADC at line 1090.

I thank you for taking the time to help me!!

I made the change to line 281,as you suggested, and now the code beyond is no longer commented out.
I compiled, uploaded, no errors, but still not seeing anything on the LED modules.

I am unable to duplicate the errors that you received.

I have to go to work. I be back when I get off.

Best regards

Hi,

The library LedControl.h requires this basic configuration of connection:

36)   LedControl lc = LedControl(11, 13, 10, numDevices); // din, clk, cs

Change this in the program and in the scheme and it will work technically.

Another thing is that the program does what you want.

Good luck...!

Thanks Defran!

My original project was a Leonardo not a Uno. I should have checked the header file for possible changes, as my original project was a couple of years ago. I try to avoid using D13 as it causes the onboard LED to flash. Well, unless you want it to flash. D12 seems to work and the LED is not blinking... LOL

SimulIDE is a friggin' nice simulator!!! Awesome!

Oh, by the way, the circuit is working now! Perfectly!!

Feel free to share my work with anyone who may like to build on, change it around, etc. Just please encourage the inclusion of the original authors' credit.

Best regards all.
