I'm still at a loss with m5ez. It is very frustrating to "have" such a great framework that I'm unable to leverage. Are there any examples of someone using m5ez in a project that "does something"?

An example of "does something" I mean like this ESP32 project I completed recently: https://www.facebook.com/144922416365/videos/743331992745660 it is a test bench I developed for ignition coils. The UI are the three buttons on the right and the display is simply a right side for status and left side for control.

This kind of UI is how most of my programs work... a continuous presentation of status or information and some instruction about control. As I rework a prior test bench into a new version controlled by ESP32, I'm driven to inaction because of how unfriendly m5ez is to utilize.

Hi,

I'm wanting to interface my M5stack with external circuits and am using a faces board. Is there any reason that none of the external pins have connections? I check with oscilloscope and there is nothing at 5v 3v3 or gpio 36. I have interfaced with plenty of circuits with ESP32, arduino, and chipKIT, but this is my first attempt with m5stack. When the base has its pins press in to the faces dock, it looks like these pins should be connected...

In the image, the red arrow is pointing to the pins I'm trying to use. Looking at the sticker, the arrow should be pointing at GND. From left to right on the image then should be 5V, 3V3, BAT, RST, and GPIO 36. I first used the header pins in the breadboard to connect and then I went into the pins of faces dock directly with o'scope.

What am I doing wrong?

I was really excited about M5ez until I started trying do something with it.

My first problem is how I'm unable to integrate the Faces calculator keyboard in with the buttons. It seems I cannot read the calc buttons asynchronously while the three buttons are still "active". ??

My second problem is that any time I try to run a function off of the main menu (trying to do similar actions as your examples), I'm never able to continue the header and UI in the way you are able to... even when it seems I copied the code well enough.

It is so difficult to integrate in with the UI, I'm choosing to just start from scratch. :(

I see the lock is in the address bar in the browser. Thank you very much. 👍💚

Original post:
If you entered your password with the broken lock in the URL bar, your password is already being sold to someone to be exploited. That password is compromised and it is GONE.

There is not enough emphasis on the fact that this forum is not on HTTPS. I hope this is a recent problem, but this thread is not enough warning.

I have witnessed when a website was misconfigured for just a day, its unencrypted traffic on the net was compromised and exploited. "Clear" traffic is automatically sniffed for things like passwords and credit cards. I'm not chicken little sky is falling, I have observed this on low traffic websites.

Seriously, the site should just be gone until it's fixed. Chrome and Firefox have plugins to generate strong and random passwords, so use those and just hope for the best.

WHAT THE EFF

Just now noticed this, too. If ANYONE logged in with any kind of variant of other passwords, you need to change ALL OF THEM now.

Chromium browser and FireFox browser both have secure password generators; please use those to log in to this unsecure forum!

I have seen instances of text sent into the clear being compromised within hours of a site not being on SSL. 😖 This is inexcusable and laws should be made that anyone asking for passwords in the clear be made to pay damaged to users they caused to enter passwords in clear text.

@m5stack does the USB module go on top of the FACES and under the Core?

Yes, I would use an intermediate driver for the stepper itself and use the MCU + USB module to send signals. I mostly assume MCU pins do not do any work beyond to send/receive signals. ESP project above uses 3.3V relay to switch 12VDC. The chipKIT project referenced above uses Sparkfun Easy Driver product. Another application with a more hefty stepper uses "Rugger Circuits" designed Rugged Motor Driver shield.

Thanks,
Chris

Hi, I just learned of the m5 stack system and am excited because it seems I won't need to build and program the UI like I have for prior projects. Just a couple buttons can add days to a prototype!

I envision a testing bench with a core, face, and joystick module.

• Is it possible to also add the USB module with core and face?
• Does it go above the face and below the core?
• USB module also has general IO pins? (I may interface with a stepper motor driver, etc)

This bench it would affix to, I will create and it will hold the face and supply power, too. I have built test benches with chipKIT and ESP32 and wish I have used m5 Stack, which looks like will be my favorite going forward.

Thanks!
Chris
