Next steps: meeting 2021/02/23

[mathiasbredholt]

• Make script to clone libmapper, liblo, and zlib repositories @mathiasbredholt
• Test the libmapper C++ API with libmapper-arduino @mathiasbredholt
• Debug memory allocation issues (stack and heap) @malloch
• Test with Arduino CLI @edumeneses
• Make submission request to Arduino library manager @mathiasbredholt

[mathiasbredholt]

I made the script for auto cloning the dependencies. The examples compile in Arduino IDE 1.8.13 / arduino-esp32 v1.0.6, but I have yet to test on an ESP.

[mathiasbredholt]

Further down the road we could make travis update libmapper-arduino automatically for every new commit to libmapper/main.

Test with Arduino CLI: Starting Thursday, May 13

[mathiasbredholt]

If the examples are working without crashes I will merge the updates into main

[mathiasbredholt]

Test with C++ API: Starting Wednesday, May 11th

[mathiasbredholt]

• I've tested libmapper with both C and C++ on my ESP board and it works smoothly :) :)
• It seems that Joe's optimizations have solved the issue with stack sizes as well!
• I'm testing with arduino-esp32 v1.0.6, where the stack size is unchanged (8192 bytes) and inet.h changed as described in fatal error: ../../../lwip/src/include/lwip/inet.h: No such file or directory #3.
• I am able to create and update 32 signals with the C++ API.
• The code is found in the Example_CppApi included with v0.3 version of libmapper-arduino

[edumeneses]

Great! Thanks for the code. I'll check ASAP

[mathiasbredholt]

I have made a new release (v0.3) and merged the changes into the main branch.

[malloch]

This is great – glad to hear the stack issue seems to be resolved!

[edumeneses]

Tested on VSC+PlatformIO (will not test Arduino CLI). Worked fine on Probatio. More details on the e-mail sent earlier this week

[edumeneses]

Libmapper-arduino implemented on Probatio https://github.com/probatio/probatio-firmware-hub-m5stickc/tree/wifimanager.

Small demo: https://youtu.be/0jFRvJSLwoE

Next step: programming some audio to map and check if sensor data is being send without issues.
