Arduino DUE with Vixen and Pixels

Arduino DUE with Vixen and Pixels

This problem comes second to my main problem of trying to get a MEGA to run 200 Pix. I thought this might be that solution.

An Arduino DUE, 32-bit ARM core micro controller at 84 MHz and 96 KB of SRAM (two banks: 64 KB and 32 KB). Thinking this upgrade would remove the bottle necks of the MEGA I bought one to try.


When trying to compile the current somewhat working code it gives me an error on a return;

Arduino: 1.8.10 (Windows 7), Board: "Arduino Due (Programming Port)"

D:\XMASFiles 2018\VixPix_Sketch_2019_DUEMod\VixPix_Sketch_2019_DUEMod.ino: In function 'int bugit(String, int)':

return-statement with no value, in function returning 'int' [-fpermissive]

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

If I remove the return; it will compile, but nothing works when ran.

Has anyone else had success with a DUE?





Working Code on the MEGA and code that isn't compiling for the DUE:

 *    - Name it what you want (Although... Jdc928IsAwesome is great controller name)
 *    - Set the channel count to 3x the number of Pixels you have 
 *    - Save, then configure these options
 *    - Com Port: choose the correct port for your arduino's Serial3
 *    - Baud Rate: 115200 (or whatever you changed it to below)

 *    - Check the box "Send a text header"
 *    - Type "VIXStart" in the header text box

I don't have a Due but I successfully compiled your code for a Due using Arduino 1.8.9.

[xGROMx]

I copy and pasted the wrong code, I had removed the error line to see if it worked. It would compile but it didn't work. Below is what works with the MEGA but errors on the DUE. Still messing with the setup.

[MartinMueller2003]

This code has a few flaws in the wait "waitForVixenHeader" function. char buffer[3] is too small. this should be coded as:
char header="VIXStart"; // this should not be a pointer
char buffer[sizeof(header)+1]; // This was too small


if(index == sizeof(header)) // never use a magic number. It will be wrong when you change the header.

Thanks Martin. Well today I had a F it moment and bought an F16v3. I was asking my self why am I fighting with this stuff. HA

I do like to work with this stuff though, I think I will continue trying to get the DUE working and test its limitations. But at least my show will not be dependant on to much DIY stuff.

I'll post back my findings after I test it out more.
