Arduino library for OLED displays driven by the SH1107 chip. Communication via I2C. Wraps Adafruit_SH130x (https://github.com/adafruit/Adafruit_SH110x). Tested using a Pimoroni Mono OLED Breakout (1.12" 128x128 pixels) and ESP32.
Cayenne Low Power Payload with Extended Data Types. CayenneLPP format is an efficient way to send sensor data over low bit rate connection, like LoRa. Wraps https://github.com/ElectronicCats/CayenneLPP.
Arduino NMEA (National Marine Electronics Association) parsing library (wraps https://github.com/mikalhart/TinyGPSPlus). Provides nodes for extracting position, date, time, altitude, speed, and course from consumer GPS devices. Tested using a NEO-6M.
Free fonts for the Wio Terminal display. To be used with the draw-string(wt-lcd-device) and draw-string(wt-sprite) nodes in the wio-terminal-lcd library (https://xod.io/libs/wayland/wio-terminal-lcd/).
Nodes to drive common text liquid crystal displays with I²C interfaces (based on https://xod.io/libs/xod-dev/text-lcd/). User can specify I²C bus. Compatible with I²C multiplexers (example patch provided).
Node for measuring the amount of free Static Random Access Memory (SRAM). Based on https://github.com/mpflaga/Arduino-MemoryFree. For more information on getting the most from your Arduino memory, see: https://learn.adafruit.com/memories-of-an-arduino.
Library provides a single node for calculating the simple moving average (https://en.wikipedia.org/wiki/Moving_average#Simple_moving_average). Based on https://github.com/ThingEngineer/movingAvgFloat which in turn is derived from https://github.com/JChristensen/movingAvg
Save data (byte, number and string data types) to the non-volatile storage (NVS) of the ESP32. Wrapper for the ESP32 Preferences library (https://github.com/espressif/arduino-esp32/tree/master/libraries/Preferences).
