Library for Sensirion SDP6x differential pressure sensors, including the SDP610. Wraps a modified version of https://github.com/EngineerTony/Sensirion_SDP6x_pressure_sens. Data sheet: https://sensirion.com/media/documents/63859DD0/6166CF0E/Sensirion_Differential_Pressure_Datasheet_SDP600Series.pdf
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.
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). Tutorial on using the library: https://www.hackster.io/wayland2/access-esp32-non-volatile-storage-using-xod-252ec9
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.
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.
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).
