@mati said in Ultra Low Power Stick, Is There a Market?:

HI,
what about this idea:
wake
connect to wifi
display to 100
read light sensor
ping m5stack.com
wait 5 sec
display go down to 30
deepsleep 10 sec.

all is native base on latest m5stack uiflow. only the ping is extra lib imported and bit modded.

When you say "all is native base on latest m5stack uiflow" do you mean the uiflow firmware or the Blockly blocks? Because I don't see a block for deep sleep in uiFlow. I'm interested in getting deep sleep working with uiFlow.

I now found the documentation about the pins (https://docs.micropython.org/en/latest/esp8266/tutorial/pins.html) and was able to trigger a callback when pressing the big M5 button (btna):

#Define Callback: def on_wasPressed(p): print("Button was pressed: ", p) B_M5 = Pin(37, Pin.IN, handler=on_wasPressed, trigger=Pin.IRQ_FALLING, debounce= 500)

@badjinn said in M5stick GREY upload/flash problem:

Solved, it was a problem with the Silicon bridge drivers. I uninstalled it and it worked like a charm. 😁

Glad to hear it, they can be an issue on their own

It's likely to do with the fact that m5stack devices have switched accelerometer chip a few times, therefore having the multiple functions allows for compatibility with previous hardware revisions of m5stack

Found more pictures of the inside after searching for magnet issues:

With the intuit to share a little more information, @clive-dent shared a possible solution:

@m5stack I really believe it will be important to do something like as in MacOS Catalina FTDI Driver, to explain how to solve. A youtube video could be a quickly nice way to propagate that procedure.

Why I'm asking that? For most of us, have no problem of have problems like that (and others of we not facing yet). It is more important for us, find quickly the solution. I know the FAQ have something like that, but It will not show details and the M5Stick-C have a LIPO battery (can explode).

Please, consider this suggestion. Because you have made incredible products and I really like to use them.

Hi ajb, I am on Mojave (10.14). I did search through the forum, but in the answers I found, the device had already been recognized as a serial port.

I did unplug and replug the device several times, but no joy. Weirdly the problem has fixed itself though! I just stepped away from the computer for half an hour and when I plugged the stick back in, it now appears as a serial port.

Thanks for your help!

I use the battery voltage to try and work out a sensible idea of battery level. Anything equal or over 4.1 can be considered full, less than 3.4 is pretty much dead, and 3.7 is generally where it'll spend most of it's time. It's not a linear drop off, so it will take some calculations to try and get it accurate around the 3.6 to 3.8 volt range. This is probably why the M5Stack library only gives 0/25/50/75/100 battery levels.

I then use battery current to know if it's charging, discharging or fully charged. By getting the value from M5.Axp.GetBatCurrent() if you see a negative value, it's discharging, a positive value is charging and a zero value means fully charged while plugged in. The values returned will give you an idea of how much current is being drained from the battery in mA, or indeed how much current is being used to charge the battery, all in realtime. On the M5StickC it would be 85mA typically when charging.

You need to look at using sprites to avoid the flickering / flashing when you blank the screen. Take a look at the example sprite projects to see how it's done. The M5.Lcd functions can be called on a sprite object, so bitmap drawing, text drawing etc can be done the same way. Clearing, and drawing the sprite happens off screen, and then is copied quickly to the screen with pushSprite() which avoids visible flashing. The examples provided show you how to do it all, but here's the basic process :

create your sprite object
TFT_eSprite tftSprite = TFT_eSprite(&M5.Lcd);

create a sprite and give it the size
tftSprite.createSprite(160, 80);

clear the sprite
tftSprite.fillSprite(WHITE);

draw into the sprite
tftSprite.drawBitmap(x, y, w, h,(uint16_t *)img, 0xffff);

copy the sprite to the screen, and let it know where to draw it
tftSprite.pushSprite(0, 0);

@ftoure hetzer was referring to the original M5Stick not the M5stickC.
@hetzer did you manage to do what you wanted with it. I find it's better to work with original M5Stick as the M5stick didn't have much functionality in UIflow even when it was supported

@eternalgrace94 said in M5stick C compiling issue:

Usually when press run, the code will upload and the device will run the program accordingly, but as of recent, I have to reboot the device so it will run the program
Anyone knows a solution to this, or is this device damaged?

I get this from time to time especially when im updating code several times in quick succession, and yeh, I just do a full restart.

If you have issues connecting to the UIFlow Website it may be due to server load as there are alot of people trying to access the server.

What about on the m5stick c

@akelix said in M5Stick OLED:

There is no Extendable Socket in new m5Stick oled module.

Is there any plans to come it back? I use this port in my devices, and oled screen is very convenient form me.
One groove port is not enough. It could not be powered only by usb-c port now.

I'm making a video on how to bypass the power limitations of the socket to power items. so far this is the raw footage - https://www.youtube.com/watch?v=DDBk7ZcKED0

This is normal in ueflow.
Turn it off.
Hold right button then push power.
Then when screen wake up release side button and push it again to force cloud.

Other way is turn off
Hold bug button under LCD and power it on.
then by using right button in under the LCD you can navigate on lets say boot manu.

Thanks! I had really a space in my WIFI name so i changed it and now it works fine!
