@juanjosecastillo Will it run on USB power?

@l2m2k2 Hi, this is just demo software for you to see before exploring with your own sketches!

You can view the source code for hints programming it yourself.

I would not worry about it!

Your link certainly did not work(!) but this did:
https://docs.m5stack.com/en/api/
But I don't see a specific api for TimerCamX !
Would this help?

@delchi RC servos are local closed loop (under their shell body) and will accurately go where you command, but as you know they do not provide feedback, like a Motion Control or Robotic servo. You have to trust that you sent it to 45 degrees and that it made it, but if it binds on the load you will not know. You may have to attach a encoder to that axis, like an Industrial Robot.

@bladehunt0
I know that this is not an answer to your problem...I use a Core Basic to control the HVAC in my home office and the top reading is:
Room Temp 24.3
Fortunately the % sign is supported for Humidity!!!
Here is an experiment!

M5.Lcd.setCursor(272, 98);
M5.Lcd.setFreeFont(FS9);
M5.Lcd.print("o");
worked surprisingly well.
The "98" is 16 pixels higher than the reading.

@bladehunt0 Well, I tried using M5.LCD.print(º) but nothing on the LCD after upload!
I think you are right that it does not support "extended ASCII", but...with a graphical interface, anything is possible...but with a ton of trial_and_error.

@bladehunt0 Hi, which model of M5Stack is this?
Core 2 and Core basic can use different graphics.

@felmue Hi, I see a number of posts where the fix is adding (int) twice in the function’s parameters.
It seems the parameters are already correct, can you help me understand what difference this makes?
-thanks, Terry

@holofloh good call, but if the // are removed then the ledc commands are “before” the open curly brackets { of the next line, so I am still confused!

@jhon-valdiviezo I have been curious all week…why is it commented out?

@earla constant pressure on the sensor to the finger is key. Make some tight elastic restraint and don't move a muscle during testing!
If you can port your serial to a serial monitor or plotter, it will be very elucidating!

Yes, you would send position or speed values to each channel.

There should be an example in the documents.

If I misunderstand let me know and I will research further.

Arduino IDE, no problem, and I’m sure it is facilitated in UIFlow.

This is all you need to get a demo running.
-You will also have to install these libraries:
#include <Wire.h>
#include <ADXL345.h>

@zappawaddawadda Hi! There is an excellent tutorial on the first page of the M5StickCPlus documents page here:
https://docs.m5stack.com/en/core/m5stickc_plus
This is for the older Arduino ver 1.8.19 and is the easiest to use, IMHO.
You get close to "machine level code" with the IDE which also accidentally teaches you C and C++ as you go along.
If you have any difficulty, post a reply here!

Thanks for the warning! I could be affected, it has happened before!

@cpersoz The nomenclature of the Demo program is a little vague, but I checked both schematics of the Core2 and the Bottom2 and 25 is the RGB and 34 is the I2S!
#define PIN_CLK 0 // I2S
#define PIN_DATA 34

#define NUM_LEDS 10 //LED
#define DATA_PIN 25

@macsbug Still very faint!
Not useable!

@starcrouz Hi, I too had an ESPNOW fully operational application completely stop working (communicating) about two months ago.
It is programmed in Arduino IDE, using C, C++. I had just updated libraries and made a small change and after re-uploading the sketch, it stopped communicating.
Here is my ESP_NOW tutorial on GitHub:
https://github.com/teastainGit/ESP_NOWpeer2peer
It is Arduino IDE, not UIFlow.
I went over my code line by line and found a small error that was acceptable two months ago...but not anymore.
So this means that they changed ESP_NOW on us!
Hope this helps, Terry

@frangimeno2000 Yes.
ESPNOW easily runs in Peer-to-Peer mode, so there is no need for master/slave or server/client configuration.
I put up an example on GitHub:

@nebosa You will need a PaHub2 I2C multiplexer!
