@guors thank you.

Sorry, I have been busy and suffering depression which resulted in my book getting neglected.

@seppel as far as I am aware they are custom sized.
if you are talking about the internal bus connector then

If you have been using arduino then UIFLow will have been deleted from the M5Stack or stick.
M5 Burner must be placed in a folder called M5Burner to work (folder has to be created manually) one this is done then the download will start working.

There are several things to try.
1st is to use a USB hub between the M5Stack and the Mac computer.
2nd, is to use a different cable.
3rd is to use a different USB programmer to bypass the CP210x chip.
4th is to try the tips the other catalina users have posted on this forum.

@pumpui With Catalina you need to use a usb hub between the m5stack and the osx computer. there are loads of issues with cat and hardware

@hanphony said in Bluetooth support:

Hmm, but this repo hasn't been updated: https://github.com/m5stack/M5Stack_MicroPython
Thats because that firmware is no longer used.
Due to the constant updates and work on the new firmware (and the lockdown) I can't see an updated repo online yet.
@m5stack have you created a new git repo yet or are you waiting untill the firmware is out of beta ?

M5stack stopped using loboris several months ago and moved to their own port. They are now working with the official branch.
There are still some issues wit BT and wifi but they are working on it.

@klimbot said in Max 5v current out:

Hi,

I'm looking to make my own hat for my M5StickC and was looking to find the max current out available at 5v. Any ideas?

Thanks.

Depending on what kind of hat you are designing, you could design it so that it directly powers you device and supplies power to the stick instead of the stick supply the power.

Create a folder called UIFlow and put the program in that.

@jhfoo
On the m5stickC, hold down the A button immediately after boot/power-on to access the menu. Then you use the B and A buttons to navigate and select.

Thanks mate, I could not remember the sequence.

it could be that the gyro is in Gravities which would explain the low reading.
I was watching a vid and normally the readings shoud be in miligravities.

@jhfoo if the api screen is showing, you missed the menu.
the stick can be an problem in the older firmware as the menu appeared and dissapeared to quick. the stick doesn't have the demo as the demo is only for the core but the menu is there.

@jhfoo use the big button on the front and the small button on the right hand side.

This was helpful. I use M5Burner to install uiflow v1.4.5.1. Using the web editor I was able to quickly learn some basic python commands.

I notice after installing uiflow I am unable to connect via COM6. Is this normal? How can I do advanced python development without uiflow overheads eg. splitting into multiple files/ modules?

To directly program the M5Stack,
Restart the M5stack and click the right hand button to enter settings, go to "switch to USB mode" and click the middle button.

Micropython mode can allow you to write more advanced code but I recommend Mu or VCode with the micropython plugin.

Use M5Burner found in the downloads section of the main website. create a folder called M5Burner, download and put the program in to the folder, open the program and you will presented with a list of firmwares available to download and install into M5Stack and stick devices.

@jhfoo the demo is preinstalled in the firmware

I think this is down to character encoding.
The default character encoding used in the firmware doesn't have the symbol.

IR unit not supported
