@felmue Just an udpate: everything is working as intended. Thanks!

@felmue
Awesome!!
I had seen that tutorial before. The part I was missing is adding that additional board manager URL. That gave me my examples in the right place, compiled and uploaded.
Thanks a lot for your help. I had spent a couple days trying to solve it different ways.
Thanks!

The esp32 bord defs in Arduino are controlled by espressif and it looks like they broke a few things.

Doh this is why I hate Arduino,
I had to change the

to

And now it works, that's mate!

@rodberry said in Mozzi sound synthesis library for Arduino - how to make it work on the Core2:

@oscillator congratulations Staffan, I'm a year late to the party but just wanted to say this is a lot of fun and I really appreciate the thorough documentation and the very readable code (speaking as a C-phobic beginner programmer).

I'm planning to make this into a module for my AE format modular synth. For now, I'll start by just feeding it into a converter but will eventually get the other components organised to make it work nicely in the system with my other modules. At least you have given me a nice wagon to fall off! :)

Cool, I am glad you find it useful! The AE modular seems great.

I can also recommend the Daisy Seed, for which I've done a few projects:

Good luck with your projects -- and your music! :)

@m5_tinker It should be, the M5Burner version is just precompiled ready to burn where as the Arduino version has to be compiled and burned.

Hello @Gorilla

thank you for reporting back. I am glad you figured it out. And yes, there were some recent changes to the EXTIO2 library regarding I2C so getting the latest is key.

Thanks
Felix

Hello @Marelli7

you are welcome. I sounds like you are having fun. And thanks for reporting back. I am glad to hear you got it working to your liking.

Thanks
Felix

@fosouza Thanks!
It took some quick-clicking, but I got the 2.0.5 installed.

Hi,
You wrote: Once the M5Stack is powered off, only the CAN information can no longer be read. So the solution is easy: Power ON the M5 device!
Or do you mean OTHER devices on the same CAN are not able to read data WHILE M5 is OFF? In this case it might be possible that the CAN transceiver in the Commu is still powered (check that!) but miss the input signal. According to the datasheet of the CAN driver chip the bus output is dominant while TXD and S pins are LOW. This blocks the communication of other devices. It may help to solder the pin 8 of the transceiver to +3.3V instead of GND to enable silent mode (switch it to Rx only) or make sure the commu is not powered. The bus driver is then going to float (Off Mode) and should not block the communication anymore.

JPG has several Cilor Mode.
Use as JPG RGB MODE
For example, you can do it with GIMP.

@mickey95 dude?

Thank you for the update.

Hello felix,

seems to work, thanks.
Will see how long m5paper could work without charge.

Hi @felmue and thanks for the help. I changed GPIO and it works now. Strange as input port 2 worked when the temperature sensor were implemented separably.

However I have spend enough time trying to make it work. So I will not conplain now that it is working.

Thanks again

@felmue Thank you so much Felix, you've helped me again.

@ajb2k3

To clarify, I think you're implying that some of the other APIs are available to me on M5Paper, but some aren't - is that correct?

Yes, correct.

Is there any way to tell which ones can and which can't? Is it API by API, or is it more granular - certain functions documented under other APIs are available?

For example, are the functions under https://docs.m5stack.com/en/api/core/power available - lightSleep, deepSleep etc?

Thanks again for all the help.
