IoT assembly station with arduino board

git clone https://github.com/ThomasZehnder/assembly-station-arduino.git

The ESP8266 requires a 3.3V power supply. see https://randomnerdtutorials.com/vs-code-platformio-ide-esp32-esp8266-arduino/

see [https://docs.platformio.org/en/stable/platforms/espressif8266.html] Add to platformio.ini

; Enable exceptions build_flags = -D PIO_FRAMEWORK_ARDUINO_ENABLE_EXCEPTIONS

// Secound Timer
#define TOGGLE_LED_PIN D0 

//D1 = SDL for OLED display
//D2 = SDA for OLED display

//D3 = WS2812 data line (LEDS need 5V, signal only 3.3V works)

//D4 is reserved for build In led -> show http activity

#define KEY1_PIN D7
#define KEY2_PIN D6
#define KEY3_PIN D5

In VSCode see elements in the buttom left corner to transfer projekt to arduino board.

SPIFFS is currently deprecated and may be removed in future releases of the core.

Use LittleFS instead

After creating and saving the file or files you want to upload under the data folder, follow the next steps:

• Click the PIO icon at the left side bar. The project tasks should open.
• Select env:nodemcuv2 (it may different depending on the board you’re using).
• Expand the Platform menu.
• Select Build Filesystem Image.
• Finally, click Upload Filesystem Image.

DEVICEID (String): Used as Identification of device and is used as prefix in the MQTT Topic definition.

ACCESSPOINT (bool): force to switch on accesspoint even WIFI is connected.

JSENABLE (bool):

• true, all resources are used from in context wit the Tiny-JS interpreter.
• false, a default IIOT assembly model is implemented, Keys, OLED, LED and MQTT are used. Tiny-JS interpreter is fully disabled!
