MOZZI Library with Teensy LC about mozzi HOT 10 CLOSED

from mozzi.

I would like to use Mozzi with the LC but the include for teensy does not seem to be aware of LC, which is the only M0 teensy. Compilation errors suggest that it thinks it's a Teensy 2 family board:

Hi,
Normally the LC does work straight with Mozzi (see #138), tested by me and working at least if you do not use I2C.

In your error message:

warning If you get a compilation error you should probably update Teensyduino to its latest version

Are both Arduino and Teensyduino are up-to-date? I had error similar when making the port with the old version of Teensyduino.

from mozzi.

I can compile if I set my board to Teensy 3.x or Teensy 4.x, but not LC.
I'm using the latest Mozzi and the latest Teensyduino. I have removed all my exotic board libraries like stm32.
I think the hardware_defines.h is making Teensy LC as AVR.

This is weird, I'll test on my setup this evening. Thanks for the feedback!

Just tested. I worked with the previous version of Teensyduino, but, after updating, I get the same error.
Actually, the error is in the ADC library of Teensyduino (or more precisely, the ADC library embedded in Teensyduino), because the following sketch:

#include <ADC.h> void setup() {} void loop() {}

Does not compile…

There is actually an (old!) PR pending on this issue: pedvide/ADC#81
A quick fix, for you, would be to apply the patch proposed in the PR to your library. I put a comment there, hopefully this will be fixed in the teensyduino library.

Will close this old issue soon as the source of the error is not Mozzi…

Hope it helps,

@tomcombriat Thanks for taking time for this!
Do I need to ping pjrc to get the adc library working?

from mozzi.

(meanwhile I will use some other boards)

from mozzi.

@bptremblay If you have the time I would be grateful. I commented on the ADC library but I am not sure a lot happens there. Probably pjrc has their own fork anyway.

Closing this as the issue is not related to Mozzi.

Note:
The ADC lib has been updated. Hopefully, this will get through pjrc next version. pedvide/ADC#81
