@frittna YAY I got it running. There was something strange with my sd card so I formatted it and out the config files back on it and now it's working. This is an awesome application you put together! This is going to be fun.

@frittna OOPS - I lied to you! I seems that I no sooner installed the esp 1.0.4 version and the ide came up and said I had libraries with updates and I must have selected update. I found this because I thought I'd double check all of the libraries and the board versions. When I looked the board had changed to the latest version so I removed it and installed the 1.0.4. In a few minutes I was prompt regarding updates and this time I didn't allow the updates!

The good news is I'm up and running but stuck at Connecting to.........

If I'm compiling this way can I still use the config files on the sd card or do I have to hard code the wifi info?

Thanks again.

Walt

@frittna Thanks for responding I appreciate your help. Thanks for confirming the Warning issue would be ok. I made certain I installed the 1.0.4 version per the instructions. I was able to grab some output from the serial monitor and it's this 9 lines constantly scrolling? Thanks again.

@frittna I'm trying to build the application using the Arduino interface and I get one warning:

WARNING: library Timezone claims to run on avr architecture(s) and may be incompatible with your current board which runs on esp32 architecture(s).

I read a few article that say it still works even though the warning is displayed so I continued to try uploading to my M5Stack

When I compile and upload it completes 100%

Hash of data verified.

Leaving...
Hard resetting via RTS pin...

However the M5Stack never does anything other than display a blank (black) screen.

Any thoughts on why that would happen?

Thanks,

Walt

I have an application running on my M5Stack (basic) now when connect the USB I can't see my device in Visual Studio Code. Do I have to burn the firmware just to get to the menu allowing me to put the device in USB mode? Otherwise how do I get to that menu before my app loads?

@world101 So I figured it out:

On that particular module I connected it as follows:

Left pin on module labeled 'S' to 5v on the righthand side of M5Stack (red wire)
Center pin on module (not labeled) to GND on the righthand side of M5Stack (yellow wire)
Right pin on module labeled '--' to pin 2 on the righthand side of the M5Stack (orange wire)
After you compile and upload the app tap the module to see the "Tap" message.

@world101 I just tried pin 3 and didn't have any luck. I'm using a Core Black.

I'm trying to connect this module to my M5Stack Core.

Description
KY-031 knock sensor module. A vibration sensor that sends a signal when a knock/tap is detected.

Compatible with Arduino, ESP8266, ESP32, Teensy, Raspberry Pi, and other popular platforms.

KY-031 Knock Sensor Module
KY-031 Specifications
This module consists of a 10 kΩ resistor and a spring-based sensor that sends a high signal when a vibration is detected.

Operating Voltage 3.3V to 5V
Output Type Digital
KY-031 Connection Diagram
Connect the module's Power line (middle) and the ground (-) to +5 and GND respectively. Connect signal (S) to pin 3 on the Arduino.

KY-031 Arduino
S Pin 3
middle +5V
-GND

On the Arduino it uses Pin 3. What Pin should I use on the M5Stack?

Thanks in advance,

I installed PlatformIO in VSCode and was able write and upload an application to my basic Core. Now when I turn off my Core and turn it back on that application is loaded. How do I get back to the regular start up screen where I can specify a USB connection? Currently the application I upload is always loading and I can't access it in VSCode any longer. I did replace the firmware once to get out of the application but having to do that to test your code in development seems crazy.

Thanks in advance,

WW
