Grovey ESP32 WiFi RTC GPIO Sketch Overview

Overview of the "Virtual Pins" Used :

Grovey ESP32 Main Board :

V0 - Reserved for Debugging messages

V1 - Current Real-Time

V2 - Current Date

V3 - Hardware Uptime in Hour/Min/Sec

V4 - Hardware Uptime in Days

V5 - "Connected" Virtual LED

V6 - "Fault" Virtual LED

V7 - ADC Channel Reading (Battery Voltage) (Not working yet on ESP32)

V8 - "ledc" channel 1 (ESP32 PWM) (thingSoC/Mikrobus PWM physical pin)

V9 - "ledc" channel 2 (ESP32 PWM) Onboard Physical (yellow) LED

V10 - sigmaDelta Digital to Analog (DAC) Channel 0

V11 - sigmaDelta Digital to Analog (DAC) Channel 1

V12 - Mapped to physical GPIO Pin 2

V13 through V15 (not implemented yet)

Grovey I2C HUB Expansion Board :
(coming in rev 3.0)

V36 Grovey I2C Hub - Channel Selection (1 of 4 I2C switch channels)

The Grovey I2C HUB is a four port I2C switch with 3.3 Vole to 5.0 Volt level translation options.
This allows you to add several peripherals with the same I2C address, on different ports.
This is useful if you need to support several identical displays (LCD/OLED/etc.) or sensors
such as temperature sensors, etc.
