M5Stack RoverC controlled with M5StickCPlus , via ESP_NOW RemoteControl:
https://github.com/teastainGit/RoverC-StickCPlus-ESP_NOW-Remote-Control
But with no JoyC, just using the second StickCPlus IMU as a 'wand' to control the Rover.
This Project requires 2 M5StickCPlus Controllers:
https://docs.m5stack.com/en/core/m5stickc_plus
or the new M5StickCPlus2:

controllers or a mix of either, but with suitable mods, mostly the include header:
@hanktttop OK. I'm wading into this discussion without having a Cardputer!
My other ESP32-S3 and M5Stack Atom S3 and several StampS3s all work very well in my Arduino IDE environment. I also have a bunch of S3 products from a manufacturer whose name cannot be said. (coughs into hand...T-Display S3).
So I am familiar with this S3 series on a M1 iMac.
My iMac has two Thunderbolt ports and two USB ports. I used the USB ports just fine for M5Stack-pre-S3-models, but the S3 models wont even power up on USB, they need the Thunderbolt outputs.
So, get to the point, teastain.
Connection is VERY fussy and unpredictable with S3.
All of the M5Stack S3 products that I have seen have both of the necessary buttons available. The Cardputer even has them at the front(!) no need to remove the S3 or peel back the sticker on Cardputer. (in fact DO NOT remove the S3 with Cardputer!)
The GO button is actually GPIO 0 and is called 'boot'.
The 'rst' button is otherwise called 'EN' which cuts power to the core when pushed and resets when released.
Method 1 unplug the Cardputer from the USB, press and hold G0 (on the left side of the Cardputer, plug back in and release G0.
Method 2 while plugged in press and hold G0, press 'rst' on the right side, release 'rst', then release G0.
In both cases if your sketch does not boot up and run, it is recommended to unplug it and plug it back in to boot.
@ajb2k3 Sure, here it is:
Here is the full example for all ESP32s using the OV2640 camera in Arduino IDE
(in the IDE board selection choose M5Stack UnitCamS3)
Remember to edit the .ino file to include your WiFi credentials!
The full sketch is here:
https://github.com/espressif/arduino-esp32/tree/cf448906b3836fbe9368934713b697469254c62f/libraries/ESP32/examples/Camera/CameraWebServer
You can choose CAMERA_MODEL_ESP_EYE, and apply a little tweak in camera_pins.h like this:
https://github.com/m5stack/UnitCamS3-UserDemo/blob/main/firmware/src/hal/cam/camera_pins.h#L21
Also in the library used in your sketch
app_httpd.cpp
I had to change Line 77 from ('1" enabled) to ('0' not enabled )
#define CONFIG_LED_ILLUMINATOR_ENABLED 0
Successful upload serial output reads like this:
20:48:24.952 -> E (516) esp_core_dump_flash: No core dump partition found!
20:48:24.952 ->
20:48:24.952 -> ......
20:48:24.952 -> WiFi connected
20:48:24.952 -> Camera Ready! Use 'http://192.168.0.37' to connect
@ajb2k3 I really like the idea of REPL !
MY(!) aging brain is resisting learning a new programming language.
In the (late) 70's I programmed in machine code and felt C was a "high level language".
I will investigate Python, could be fun!
Cheers to all.
Hi, I have a Core Basic HVAC program communicating with two Stamps using ESP_NOW and they are physically close, but the idea was to not run messy cables! The ESP_NOW is peer to peer WiFi, but no login to the internet or even the WiFi router.
One Stamp reads the HVAC vent temperature and reports to the Core, which in turn calculates the damper vane angle and transmits that back to the very same Stamp connected to a 180 servo motor.
The other Stamp just operates one or two small under desk heaters as required, by the Core.
Hope this helps.

@coolman626 This is sadly a confusing aspect of Arduino IDE V2...a "feature" that guesses your board as a "convenience" and it's always wrong.
In the search box start typing M5Stack until you see your board!
Really no big deal!
-Terry
@mhuis M5Stack uses 5V on the grove cable to cover all bases!
Most sensors today are 3.3V, but if one is still 5V, it will work.
Then any M5Stack brand sensors will have a step down power converter to it's internal 3.3v requirement.
The I2C is 3.3v.
The 8 Encoder is 3.3v. on the inside (STM microcontroller).
No logic level converter is needed.
@felmue "For testing integrity" I'm using the github EXT.IO Zip download and running the DIGITAL_INPUT_OUTPUT example right from there and then later from my Arduino directory, after checking that both Libraries M5Stack And EXT_IO are up to date.
Note, stubbornly I am using Arduino 1.8.19.
The Example would not run until I added Wire.begin(21, 22); delay(1000);
Seriously. I take it out and the sketch throws errors.
I am also disappointed that setPinMode "came and went".
I am becoming discouraged with M5Stack, unfortunately.
@mtylerjr The Core Basic has 15 GPIO peripherally arranged in the battery base, as well as generous grounds and voltage options.
@lordryck They are called Grove and are the standard for most M5Stack products.
https://shop.m5stack.com/pages/search-results-page?q=grove cable
Also used by Seeed products.
They're JST connectors type 'HY2.0-4P'.
Not sure 'Who Cares' but The Internet, especially on WiFi, has been flakey recently.
I made a Arduino sketch for the StampS3 and an aftermarket OLED last week.
So I ported it over to a Stamp-PICO:
https://shop.m5stack.com/products/m5stamp-pico-mate-with-pin-headers
(Stamp-PICO require a separate Programmer.)
Also suggest The StampS3 (with built-in USB):
https://shop.m5stack.com/products/m5stamp-esp32s3-module
and the new very small mini OLED product.
https://shop.m5stack.com/products/mini-oled-unit-0-42-72x40-display
It is my first Dual Core sketch and I am now hooked.
It also made the porting much easier, just changed the graphics in the Core1 and left Core0 with the WiFi and Net tests unmodified.
(that is a Canadian Nickel 5cent piece!)
@sl4sh00 To put it into 'download' mode you can do as @robski suggested or:
Press and hold the G0 Boot button...while holding it in, press and release the reset button, THEN release the G0 Boot.
While doing this you can check the connection status in whatever burner app you are using.
Please tell us if you can see the connection status AT ALL, this would be helpful in solving your problem.
Hi Mike:
The Arduino IDE is a program environment using a very easy and convenient version of C, with some C++!
Very user friendly, but easy to get started. C compiles and overwrites everything in the ESP32.
Python is very easy to learn, but it is an Interpreted Language with a large memory usage in the board's core.
C is a world wide standard because it gets as close to the metal as you can stand.
I've been using Arduino IDE ver1 for ten years The new version 2 is more powerful, but more confusing.
@hanktttop Seeing that this is a "Flipper" type hacking tool...maybe it attacked you and is deauthering you.

WiFi SSID Scanner - Display 2.4 GHz SSIDs nearby, get information about them, and even clone the SSIDs in NEMO Portal
@mtylerjr Thank you for this info and link.
Sidenote: The unique thing about the Core Basic is that it comes with a lot of I/O broken out at the sides of the base/battery box.
Two sides are female connectors and the other two sides are the directly corresponding male pins.
This was in a time gone by where beginner projects had a lot of single pin discrete sensors.
Later, the built-in I2C became more popular and of now my big HVAC desktop controller has zero discretes, one I2C temp sensor and the rest of the I/O is the built-in ESP_NOW, which is amazing.

Currently it seems that the Stamp ext IO2 can only be in one mode for all pins, set by the command: (for example)
extio_io_mode_t mode = DIGITAL_OUTPUT_MODE;
or
extio.setAllPinMode(RGB_LED_MODE);
Also like the RGB mode to support a string, not just one SK6812.
Thanks for listening.

Hi Thomas. The desk is wooden.
But you can expect typical range and "through walls" of a WiFi router in your house.
WiFi uses quite a bit more current than you might think.
I run mine on 5V iPhone white cube USB power supplies.
@Dan-Perren Me too!
After 'letting' Arduino IDE update a bunch of boards and libraries...
It started to happen.
fatal error: rom/miniz.h: No such file or directory
Best fix was revert to M5Stack boards to ver 2.14
(3.20 was the problem.)
cheers
@frank26080115 I think we all get them...M5Stack just trying to create interest in RFID sensors!
