Day 3
AJB2K3- M5Stack Controlled Model railway
Enrico Casti - M5Stack GPS for Hiking

@myxiplx the official downloader shorts en and G0 momentarily to get the stamp into programming mode. With the drivers causing problems the serial terminal can be a pain. What software are you using for the terminal?

This year I challenged myself to clear my workbench by making 25 project before the 25th December and I have opened this up to the M5Stack community.
As its only just started here are the first few Projects.

Day 1
AJB2K3 - Christmas Countdown

Day 2
AJB2K3 - Christmas Present Weight scale
GPerrella - M5Combo ENV

Day 3
AJB2K3- M5Stack Controlled Model railway
Enrico Casti - M5Stack GPS for Hiking
Hans-Günther Nusseck - Atom Data Monitor.

@daniyyel said in cant flash latest m5 stamp c3:

after much work, got esp-idf to work on a Mac running Big Sur, and
get the same error. I'm waiting to receive a esp32c3 not from M5 to see
if it has the same issues. BTW, espressif is very silent
bleeding edge of technology :-(

Its an issue with drivers on OSX and the change in ttl chips.

Server is in China and prone to drop outs.

@fr3nd I was just about to say that it is an issue with the way the image is saved.
I started making a document here :https://github.com/Ajb2k3/UIFlowHandbook/blob/master/En-Coreink-V2.pdf

You should be able to use it as a RGB Unit but you may need to define a custom port just to flip which IOpins to use.
by default the pins are set as 33/32 and so if you select custom port you can try setting them to 32/33 (flipping the defined IO pins around.

Opps that should be 32 and 26 changing to 26 and 32, Sorry!

@m5stack UIFlow 1.8.7 pico no longer runs the UIFLow connect code but 1.8.6 does.

There is an experimental feature of Micropython called webRPEL

Have you tried setting the correct servo port and selecting the correct GOplus?
The Core2 uses a goplus2

Hello @felmue is correct, the C3 is the only one with usb built in.

@labixiaoxin8888 No need as the API key is stuck on the front of the stamp.

If you install Thonny and run the terminal monitor, the API's for any device connected will be shown in the terminal for Micropython.

@hermes Arduino only

@plusulli failure on 1.8.7 coincides with the utter ballsup that was the last apple security update which killed F360

I have this error on several devices now.

@plusulli said in UIFlow 1.8.7:

@plusulli
No one responds am I the only one who has problems with this Uiflow version

What OS X version are you using?
Safari is rubbish, I use Firefox or chrome on OS X.

I have an IDF demo ready but the OSX driver issue is driving me bonkers on Catalina and yet to get the demo uploaded to the C3

M5Stamp-C3

While I realise it's a different core but I've been having fun with the M5Stamp-Pico which does use the same LED controller so I wonder if this will help with the ops question.

I use the Arduino-IDE and the FastLed module. I've attached a snippet of code where the LED is White while searching for the wifi and Green when connected. It then flashes Blue when data is received.

More about FastLed can be found here:

Thank you for the demo but alas the Pico and C3 are two different chips. The Pico runs on Tensilica cores while the C3 runs on a RISCV core.

I have this issue as well and seams to be a known issues with ESP-IDF.
Unfortunately there is no UIFlow yet :(

You can't directly as Arduino is written in a version of C and UIFlow is written in MicroPython.

You would need to learn how to port the Arduino commands into Micropython commands.
