I am trying a new CO2 Unit with M5Core2. Libraries are all installed and I get this compilation error:
In file included from c:\Users\Gordon\Documents\Arduino\libraries\M5Unit-ENV\src\unit\unit_BME688.cpp:10:
c:\Users\Gordon\Documents\Arduino\libraries\M5Unit-ENV\src\unit\unit_BME688.hpp:30:10: fatal error: bsec2.h: No such file or directory
#include <bsec2.h>
^~~~~~~~~
compilation terminated.
exit status 1

I looked in the M5UNIT-ENV library and cannot find bsec2.h
Any help appreciated thanks.

Thank you.
I hope M5 or espressif can fix this bug soon.

With Arduino 1.8.19

Question

Hi, can anyone please help with my uploading problem?
I have used M5Core2 successfully and now have M5Tough.
I have loaded the M5Tough library and
selected the correct board, M5Stack-Tough.
I have selected the correct port when the M5Stack-Tough is plugged in.
When I compile and upload any examples for M5Tough I get the following error message after a successful compile:

Sketch uses 835953 bytes (63%) of program storage space. Maximum is 1310720 bytes.
Global variables use 40444 bytes (12%) of dynamic memory, leaving 287236 bytes for local variables. Maximum is 327680 bytes.

Any help to identify what is causing this error would be welcome.
Thanks.

During compile I found this error message:

Hi, when I plug in M5Paper COM port 6 appears and I have selected it, but still get that error message.

I have also used Easyloader to upload Calculator and Factory Test successfully and that showed COM port 6.

Hi, I have a new M5Paper 1.1 and Arduino 1.8.19.
I have selected the board M5Stack-Paper and the port.
With my M5Core2 I have no problems, but when I compile and upload any program to M5Paper I get the following error message:
