@yu_with_a_mission said in M5Burner does not work in MacOX 12.3.:

@yopita
I tried you way and get another error,
"File"/Applications/M5Burner.app/Contents/Resources/packages/tools/serial/tools/list_ports_osx.py", line 32, in <module>
kIOMasterPortDefault = ctypes.c_void_p.in_dll(iokit, "kIOMasterPortDefault")
ValueError: dlsym(RTLD_DEFAULT, kIOMasterPortDefault): symbol not found

Burn Failed
================="
How can I solve?

System:
MacOS Monterey 12.4
Device:
M5StickCPlus

There is an Issue Montery.
Have you installed Xcode from the App Store?
Have you instilled the latest Python 3 from the python site?
Have you installed the drivers?
Have you set the PATH variable correctly?
Have you copied the M5Burner V3 to the Applications folder?
Have you erased the controller first before writing the correct firmware?

@robjasey said in Where is asyncio?:

So I tried help("modules") to get the list of all modules. Turns out there is a reference to "_uasyncio" but the object looks like it is only a shell of a module. It has references to a Task class and TaskQueue class but no functions. An attempt to use _uasyncio confirms this. Sigh.

Well that's a pain.
Sorry I can't help more.

Hello @learly6

I don't think you can use a PbHub for the TCS347225. The PbHub is meant for simple I/O whereas the TCS347225 is an I2C device. Did you mean a PaHub - which acts as an I2C switch? But normally you only need a PaHub if you have multiple of the same sensors which share the same I2C address.

Hello @HWTaro9

according to this post you can at least use it with M5Core2 using Arduino.

Thanks

I've been trying to record them but its slow going without proper documentation. if you want to look into them yourself you need to learn how to use REPL to access the help/DIR function.

Hello @IndianaTux

that is interesting. I am curious about whether this actually works.

BTW: looks like the proposed fix has been included in the latest M5CoreInk library.

Thanks
Felix

Hello @jterrell

not sure if this documentation contains all M5Paper Arduino functions, but it is a start.

Thanks

Hello @MoodyGeorge

afaik M5StickCPlus and unit cam do not work together. Possible reasons:

• unit cam returns a jpeg picture, but M5StickCPlus library doesn't support / implement jpeg functions
• unit cam returns a picture with size 320x240, but M5StickCPlus display is only 240x135

I am not saying it is not possible, but it seems it has not been adapted for M5StickCPlus as I cannot find an Arduino example nor is it available in UIFlow (hence greyed out). Sorry.

Thanks
Felix

Hello @mengxiyou

I had to download M5Burner v3 to be able to download / burn v1.9.9 or newer.

Thanks
Felix

Hello guys

The issue is a divide by zero, caused by the ledcSetup(TON_PIN_CHANNEL, 0, 13); function call found by @a4x4kiwi (thanks for that).

I found that the outcome is different depending on the Arduino version used:

• Arduino 1.0.6 - no error, no crash
• Arduino 2.0.1 - no error, no crash
• Arduino 2.0.2 - crash
• Arduino 2.0.3 - error, no crash

E (4532) ledc: freq_hz=0 duty_resolution=13
[  4537][E][esp32-hal-ledc.c:75] ledcSetup(): ledc setup failed!

Thanks
