LED Animated Sand

[sailsailor]

Got it all assembled and software up to date, libraries installed, compiled and uploaded. I am missing something as I can't get it to function. Only thing I can visually notice different from instructions is I don't get the red screen. Does tell me verify and upload successful. Accelerator board has green light, orange light on feather, matrix does nothing. Any help mucho appreciated.

Please provide more details: Exactly what hardware are you using? Please post clear photos of your, projects, and the various connections.

Following is list of installed components:

Adafruit Feather MO Basic Proto-ATSAMD21 Cortex MO
Adafruit LIS3DH Triple-Axis Accelerometer (+- 2g/4g/8g/16g)
Adafruit 15X7 Charlieplex LED Matrix Display FeatherWing Yellow
Wouldn't I receive error messages if wiring was incorrect?

[dastels]

You wouldn't get build errors, that has nothing to do with wiring problems.

Again, please post clear photos of your project, and the various connections.

Thank you for the feedback. I think my problem is with loading the sketch to make it work. I loaded Blink to see if I could get that to work. Appears to be working, see photo. That's only the redlight on the Feather MO, blinking once per second as advertised. The green light is on the Accelerometer, nothing on the Charlieplex Matrix. My question is, can I verify anything without disassembling the project? I will if I have to but I double checked prior to assembling.

[dastels]

Try verifying each component without disassembly. I.e. run the accel demos, run a matrix demo, https://learn.adafruit.com/adafruit-15x ... de-2998477 would do.

I try running the code for verifying each component, as I do with the blink and this is the error message I get:

Compilation error: invalid preprocessing directive #SPDX

Thanks for your help. I'm new at all this code work at this level, I still have problems with windows 11. Been away too long. Should I be breaking the code into sections?

[dastels]

Hmm. exactly what code are you building?

Dave

[sailsailor]

the ones you suggested. https://learn.adafruit.com/adafruit-15x ... de-2998477 on Arduino IDE 2.0.4. I use new sketch then paste the code. Just like I did for the blink code. Only get the compilation error.

[dastels]

Yeah, sorry that's Python code. Use they C++ demo: https://learn.adafruit.com/adafruit-15x ... mo-1953993

Not sure what I'm doing wrong but I have the correct libraries installed and copy and paste into new sketch and this is the result I get:

Compilation error: 'Adafruit_IS31FL3731_Wing' does not name a type

Should I disassemble and check wiring?
I really appreciate the assistance you are providing, thank you.

[dastels]

No, open the example from the file menu: File->Examples->Adafruit_IS31FL3731->featherswirldemo

Mine doesn't say featherswirl demo, just swirl demo. I try it, it compilies, uploads then nothing.

[dastels]

Check all the connections to the matrix. Since nothign happens, pay close attention to the power and ground connections.

Dave

Disassembled and checked continuity of all wiring, all checked good. Then checked DC v at the matrix board and it was 3.2v, analog meter. Don't know if that matters. I then plugged it in and tried to load, same message compilied, and upload, no joy on working. At a loss where to go from here. You can check my wiring from photos, maybe I hosed it up somewhere. Thanks again for your patience and assistance.
