I did change some setting but it looked like the were not saved or were altered.

@clocey

Here is a simple flow that you can program on each M5StickC device that will send (Tx) and receive (Rx) a counter value using ESPNow.

I'm using broadcast to send the counter values, so will send data to all devices listening on the ESPNow network.

To make it point-to-point, you could use the "Add peer" block with the mac address of the other device within the flow and then use the "Send message with id" block to send data to only a specific device by its mac address.

If you had more than two devices on the ESPNow network, you would add multiple "Add peer" blocks (also changing the mac and ID values for each one) and multiple "Receive mac_address" blocks (also adding the specific mac you want to receive data from) to distinguish who was sending the data and who could receive the data.

Hope this helps!

@ajb2k3 thanks for reply, but got a deny. Hope someone will do a working sample. M5 become tetris and given to kids until it dies.

Is SD UPDATER different than SD Updater? I was thinking you wanted to load additional apps to an SD card and launch them from the SD Updater menu. Is that correct?

Otherwise, if you want to flash other standalone apps (not launched from the SD Updater menu) to the M5Stack Fire and you are using Arduino, then no that is not possible (to my knowledge). Once you load a sketch to the device, writing/flashing another sketch will overwrite the first.

If using UIFlow, it has a built-in Apps menu. You can download many MicroPython programs to the device and select the one you want to run from the Apps menu.

While it's not exactly what I'm looking for since the wio terminal example is more of an external display, while the example you've linked is purely a tty display (excuse me if I'm using the wrong terminology here), it seems like a cool alternative as well.

How one would go about to program this is beyond me, but it'd be awesome if you were to be able to get it to work!

Problem solved.
I connected the GPIO0 to GND and the board stoped the deepsleep loop, and i can run another code with :

Just an update. I noticed that uiFlow now supports Unicode characters. I'm not sure in which release it was introduced, but I'm now able to add the degree symbol to a label using characters from this site.

Two drawbacks...

@medy said in Getting Started:

@ajb2k3 I solved the not saving issue by googling and finding out about the execute block.

https://forum.m5stack.com/topic/1702/uiflow-does-not-save-python-code/4

That solves the saving custom code issue.. so thats cool.
Im not a total beginner so naturally I wrote some custom code... and didnt follow any guides or handbooks much.... basicly came in winging it

anyway this is good enough for starters.
Also having a user interface is really nice.

Thanks for the help

ps the handbook is also out o date and doesnt mention that you have to switch from app mode to usb or internet mode. during the intial setup and pairing for uiflow (the interface on the device is totally different on the latest version)

Hope you can use this feedback ;)

Opps, sorry, thanks I will update the Handbook soon but have been busy.
I have several projects for M5Stack that I'm working on and only just got to start logging the execute block.

@ajb2k3 said in Connecting Epaper display to m5stack core or other models ? (Waveshare):

ahh, its an spi device so will have issue with the internal spi screen.

There is an Epaper M5stack device in development but you would be better off with this device

if there is one in development I will wait ;D

@somedude

Hey, did you have any success and got it to work?

Would be awesome if you coulde provide an update.

greetings

So if anyone else stumbles upon this...

I had M5.powerbegin() in my code, and that will of course enable i2c, so that's the reason for my issues.

@bit2020 this is the normal demo code

@iamliubo Komix?

Installing the silabs Silicon Labs VCP Driver.pkg worked for me also. 👍
(on OS X 10.11.6)

Seems obvious that we need the drivers, but I thought I already had them after going thru the espressif/arduino-esp32 install steps.
e.g. My "System Report / Hardware / USB" showed
CP2102 USB to UART Bridge Controller driver

For others' future reference, you should see something like:
n8s-iMac:nleon$ ls -al /dev/tty.*
crw-rw-rw- 1 root wheel 18, 2 Jul 4 11:14 /dev/tty.SLAB_USBtoUART

Regardless, thanks for the pointer!

@reganel You could save the image to a file and load it back to the display, but with frequent writing to the flash memory, you will damage it very quickly. I tried to load a bitmap into a variable and draw from it pixel by pixel on the screen, but esp does not have enough ram memory (for a 24 bit 80x160 bitmap some 38kB). From what I've seen, the C libraries for arduino allow you to write an image from a buffer. The only thing I was able to get is reading a jpg image through mqtt (size about 10kB), saving to a file and from a file to the screen. But as mentioned before, flash memory has a limited number of write cycles.
