Using Core2AWS I am trying to recreate the demo seen at https://www.youtube.com/watch?v=FKJD4hg5CvA

Due to the lack of documentation I can not easily tell if my problem is using the wrong port, the wrong pin numbers or something else. I have tried to recreate the environment as best I could make out from the video,. Any suggestions welcome.

Ahoy all!

How do you communicate between a CORE2 ( or CORE2AWS ) and a UNITV2 so that you can get tracking information from the camera to the processor? I have run the demo software / web site that comes with the UNITV2 but I do not know how to get that info serially from the camera to the CORE. My goal is to take the tracking info and move servos to keep the camera on a single object.

I'm running a CORE2-AWS , powered by USB , with two 180 servos and an OLED module.

My software does a number of small tasks, nothing too intensive, and the servos do not run at the same time, or very long. The curious part is that at first I had only one servo - and it's job was to rotate the CORE2-AWS while it showed an avatar ( Stack-Chan ). After adding a second servo ( with provided capacitors and breadboard ) suddenly the system had an odd habit of turning itself off w/out any errors or warnings. I tried swapping ports around, but that didn't change anything. I thought also that maybe one of the servos was defective so I swapped it out but again after some time of running it turned off.

MY current thoughts are that it may be a power issue, but I can not find any info on how to attach supplemental power, nor a recommendation as to what M5STACK module that can take external power that would fit my needs. IT has also been suggested that it might be a software issue, but I can not see any errors, and I have reduced the code quite a bit to like 1 or 2 basic functions and it still happens. If it is a matter of power/overheating/somethign else there are no error logs to look at to see why it shut down.

Open to suggestions! Any thoughts ?

That's some good info. Is it possible that if it binds that it can cause the controller to shut off? I'm having an issue with that.

What I ended up doing is making 'servo_init' function that inits the servo making it go to it's home of 90 degrees, then setting a variable and updating it each time I move the servo.

I'm open to using other servos that keep track of such things, but I dont' see any for sale on the M5stack website and would be clueless on how to attach them / address them.

@ajb2k3 Good to know. Thanks!

I'm running a CORE2-AWS with the OLED module using micropython via UIFlow, and coding in micropython directly using VisualCode ( not Blockly ).

Surfing around the net I see a lot of people with large fonts, scrolling and other things in the OLED. Most of what I found is in C / C++ and so on, which I know nothing about. I have found a few libraries, but no documenting on how to use them.

So far I have made my own side scrolling and vertical scrolling functions, but I'm looking for things like larger / different fonts than unit.OLED has to offer.

I realize a lot of people are using C and other platforms and such, but to be honest I'm ok with micropython and I'd rater spend my time making things than learning a new language with such a steep learning curve. I'm here to have fun, not re-create the stress of my job during my down time :)

Any suggestions ?

Are there any servos out there that are capable of reporting back what their current angle is? I know there are ways of tracking with code and other tricks, I'm just curious if there is a servo that will tell you if asked.

Running the on line version of UiFlow 1.10.8 for coding, having burned UIflow to my core2 , I have some questions about using Emoji.

in the GUI you can drag and drop a emoji grid, or a block that sets a specific block in a grid to a color. This is a great start, but there are no blocks for setting the background image , size or anything else.

If you look at the python code , you can see : emoji0 = Emoji(7, 7, 15, 9) .. I've searched for hours on google but no where can I find the syntax for this. Through trial and error I found that the first two digits are the number of blocks in the grid ( x,y ) but the last two seem to be some kind of scaling of the grid size or something I'm not sure of. Likewise I can find no reference to setting the background image, or doing anything else with the module. The most I can find is how to use unicode to display existing emoji.

Where are the docs for this ? The only docs I can find stick to using blockly, and do no tell you HOW to change the background image or what that first command does, but they do mention it.

@delchi said in Possible Bug On Image Hide/Show:

Core2Duo
Firmware : UiFlow 1.7.4.1-Core2
IDE : UiFlow 1.7.4

What I'm trying to do :

• Display image 0 ( PNG , in Flash , 330 x 240 36.4 KB )
• Wait for Button A to be pressed
• Hide Image 0
• Play WAV file ( SD card )
• Show Label0
• Wait 5
• Show Image 0

What happens :
Everything works, with the exception of the image show/hide/show. It constantly shows after button A is pressed. Wave file pays, but no change to the image.

Coded in Blockly,

Python :

from m5stack import *
from m5stack_ui import *
from uiflow import *
import time

screen = M5Screen()
screen.clean_screen()
screen.set_screen_bg_color(0xFFFFFF)

image0 = M5Img("res/Untitled-2.png", x=0, y=0, parent=None)

def buttonA_wasPressed():
  # global params
  image0.set_hidden(True)
  speaker.playWAV('/sd/accepted.wav', rate=44100, dataf=speaker.F16B)
  wait(5)
  image0.set_hidden(False)
  pass
btnA.wasPressed(buttonA_wasPressed)

image0.set_hidden(False)

Bump ?

In this blockly code, it does not appear to knwo the difference between a button a press and a button a long press.

When button A is pressed, it does the steps in Button A pressed , then the steps in button A long press. Nothing I have tried makes it do only the long press block.
