UIFlow 1.7.3

[ajb2k3]

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

@ajb2k3 Which device are you using? I'm using 1.7.x with Thonny on several devices but there are some differences (the m5stickc does not work with every usb-c cable I have for instance). The device needs to be in USB mode but you probably know that.
Also it does not always work smoothly but it does work. Sometimes I need to restart the device after several times running my code. After resetting I need to use CTRL-C to get to REPL before I can upload and run my code. On the M5StickC, after pushing (uploading and starting, with F5) I need to CTRL-C again to stop the get standard interface and get my code running.
I hope this helps for you. If there are simpler ways then please let me know!

@ajb2k3 Argh great! I submitted a reply and the forum just discarded it without an error. I will type a quick recap: First of all - what device are you using? I'm using several devices on v1.7.x with thonny. It's not a smooth experience but it works. The procedure is not exactly the same for the different devices.
On the M5StickC not all of my usb-c cables work. Also on that device, after F5 to upload and start, I need to use an extra CTRL+C to stop the uiflow interface on the device, before my code finally runs.
I hope this helps you and if things can be done easier then I'd love to hear the suggestions / solutions as well!

@weezer i was using stickc's on 1.6.3 and it worked well in uiflow and not usb mode.

Just the online version then? As usual, the desktop version is not the same version as the online version. Features just appear or disappear with no explanation. I am finding learning with this equipment frustrating. Mention of education has been dropped from the website in the recent overhaul. All M5 seems interested in now is industrial applications and AWS. Hey ho, I guess they are a business and need to make money to survive.

Oh you must be new here :lol:

@m5stack SDCard missing from the M5Paper.

[felmue]

Hello @ajb2k3

I don't think M5CoreInk has an SD card, does it?

Thanks
Felix

[ajb2k3]

@felmue opps, just edited as I though both had an sdcard.

Hello guys

just found that UIFlow firmware 1.7.3.1 is available.

And Pa.HUB on M5Core2 now works. Yay!

Thank you very much M5Stack engineers.

Cheers
Felix

@felmue
Please include the use of the PaHUB in the next release of the M5Stick C/plus and ATOM.

@felmue False joy ! the PaHUB is now recognized by CORE2 with 1.7.3.1.
But only the first connected I2C module works, if you connect another I2C module it is in error. Tests carried out with Ultrasound, TOH amp, Joystick modules ... whatever I2C module you connect to in PAHUB0 is working, all the other ports are in error with message: Joystick unit maybe not connect or Ultrasound nit maybe not connect.

Hello @Peter

I'd love to. Unfortunately I am just a user like you w/o access to UIFlow source code.

Hopefully M5Stack engineers will look into that soon.

Thanks
Felix

P.S. As a work-a-round in the Python tab you can modify the line for the unit connected to Pa.HUB manually. Not ideal but this works for me.
E.g. from

AMeter0 = unit.get(unit.AMETER, unit.PORTA)

to

AMeter0 = unit.get(unit.AMETER, unit.PAHUB0)

[felmue]

Hello @Arno

I think set pos X open is the wrong command. According to the help text it only opens one position and closes all others. Try set pos X state open instead.

Thanks
Felix

[Arno]

Just by adding the PaHUB + ultrasound + Joystick units without any line of code, I have an Ultrasonic unit maybe not connect error.
It's the same with other I2C units

[felmue]

Hello @Arno

I only have an ENV and Ameter unit and I can use them together just fine with the Pa.HUB and M5Core2.

• Do the units work ok, when used w/o Pa.HUB?
• Does a single unit work on all ports of the Pa.HUB?
• Are you sure you have your units connected to the correct ports?
• Did you try to reset M5Core2 in case some previous code is running?

If it's only some units that fail I am afraid I cannot help as I don't have any other units to test with. Sorry.

Thanks
Felix

@m5stack Great Update!

I try AWS blocks on 1.7.3. In this version subscription don't work(MQTT connect and publish is fine)

Then I try 1.7.3.1. This version don't connect to AWS IoT Core.

Is there a way to see the device log?

Hi @fonix232 @ajb2k3 @robalstona @Arno @felmue @weezer @Thrasher @Peter ,
Sorry to everyone, today I will deal with the PAHUB problem, please forgive me for not solving it for a long time.
Regarding the open source requirements you mentioned, I can't make a decision at present, please understand.

Have you made sure AWS is set up properly?

@iamliubo M5Stack isn't open source and never will be. They will never disclose their micropy libraries (well, not even documentation).
All questions here about it are taboo and will be left unreplyed. Best solution is to use UIFlow blocks if u want to prototype something. Otherwise its better to switch to another hardware. However, I love build quality and designs.

Hi @sparkgene ,
Just missed AWS Start block.
