When you install UIFlow and finish setting up the wifi, the API key will be displayed on the screen along with the mode and the network you have connected the device to.

Hi, My name is Adam and as the M5Stack community grows everyday I thought I would be interesting to see who is active here and what part of the M5Stack environment is interesting to you the most.

For me is has to be UIFlow as it is the first environment that has allowed me to work with the ESP32 family without major difficulties.

I’m currently working on a UIFlow handbook and some STEM projects.

I have shared a little about me, is anyone else willing to join in?

I have spent the last five months working on the English version of the handbook which is predominantly aimed at UIFlow however due to the ever changing world of electronics, nothing ever stays still for long which makes pinning down a completion date near on impossible.

I have decided to continue to release the Work in Progress version on the forums for people to give feed back and submissions with a print published version available near December.
I wont release updated versions of the print copy when new hardware is designed but instead will be releasing update volumes to accompany the print copy.

Electronic versions are planned for the many ereaders but will wait until the manuscript hits a stable release.

Each print copy will have a contributors section where I add interesting work done by the members of the forum if they give permission.

The decision to release it like this is down to the fact that the current manuscript is already at 100 A4 pages long and I am yet to cover all the basics!

All support will be gratefully accepted and to show the progress of the manuscript so far I have attached the current version on github.

I'm slowly creating a book for UIFlow here https://github.com/Ajb2k3/UIFlowHandbook
so any feedback is appreciated.
BTW if you have Facebook you can see updates on the M5Stack facebook group.

@noiseislife said in Looking for MicroPython module documentation:

Is there any comprehensive documentation for the python modules such as m5stack, m5ui and uiflow?

I would like to figure out what functionality exists outside of what is presented in the Blockly UI.

Thanks!

I'm working on it at present but I'm behind schedule.
You can access the current update of my book here :

Grove is a standard of cable design created by seedstudio as you have noticed.

It uses a 4 pin JST-PH connector with a 2mm centre between pins.

There are 2 main cables latching and non latching. Latching is used for sensors and actuators that need to be connected to controllers where as non latching is needed to plug into the controller (M5Stack/ SeeedStudio Wio).
You just need to snip the latch off of one end of the cable to plug into controllers or devices tat have the clip covered.

There are also 2 varients of the cable on the market one has the colours Black, Red, White, Yellow, and the other has Black, Red, Yellow, White.

There are however additional Seeedstudio/M5Stack cables that are
Grove 2 Grove,
Grove 2 Stemma,
Grove 2 Dupont Male,
Grove to dupont Female.

@Zontex why have 2 seperate API's for the Coreink and the EPD, Could you not merge most of the API's into one unified e-ink api?

@m5stack what has changed in the firmware as i cant use thonny and UIFlow at the same time in the 1.7 branch.

@doubleness !
You need to have the "Set Screen Show" block as the information is only stored in memory and not drawn to the screen until set screen show or set screen partial show is called.

DIMI those "Special Nozzels" are called Ferrals or Bootlace ferrals after the things that go on the end of boot and shoelaces.

Please be patient.
This is the holiday season after all.

Just a quick vide showing a neopixel running on an m5camera (replaces firware so camera is not recording.

Thank you

I was on the Japanese FB group talking to Jimmy Lou this morning about it.

@ryumei said in Connection issue?:

Thank you @ajb2k3

I have tried reinstall the driver in administrator mode
according to your instruction.
And also I get new USB lead another maker.

Unfortunately, in my case, the issue is not changed.
My M5Basic was not worked (and M5Fire was worked well).

I will try a little more.

Don't give up, this drove me crazy for 4 weeks and I ended up getting this lead
https://amzn.to/2XXxa6J
Before it worked.
I tried 4 new leads spending around GBP£30 on leads in the end as it turns out that not all leads are true usb C data compatable.

This is an issue with the CP210x driver and all us mac users have experienced it.
How I got mine to work was a bit of a mystery but you need to delete the driver you just installed, power down the mac and leave a few seconds. Start up the mac and wait let it settle for a few minutes.
DO NOT PLUG IN THE M5Stack YET!
Install the driver in administrator mode and then shut down the mac again!
Power up the mac and when finished loading open up the Arduino IDE.
Throw away the little black usb lead that comes with the M5Stack and by a good quality USB C Data SYNC lead (phone charger leas do NOT work!)
Plug the new lead into the M5Stack and then into the mac,
wait a few minutes for OSX to mess around loading the driver.
Go into arduino and check if the port has appeared in arduino.

This driver is very frustrating and for a while I was using a USB to UART adapter to communicate with my M5Stack until i got it to work.

@ryumei I am so sorry, I completely forgot about the capacitor trick as its hit and miss if it works.
Glad it works for you now. (I have the capacitor sat in the box with it.)

共有してくれてありがとう。

I've got several on the go.

Working now.
