Peripheral Ecosystem
Supported Protocols & Interfaces
GPIO & Digital I/O
Pull-up/down resistors, hardware debounce, interrupt triggers, high-frequency PWM outputs.
Analog (ADC / DAC)
Sensor voltage scaling, raw calibration curves, moving-average filters, threshold comparators.
CAN Bus
Controller Area Network frame transmission, mask filtering, telemetry parsing for mobile & industrial machinery.
I²C & SPI Buses
Hardware peripheral communication with OLEDs, accelerometers, temperature sensors, and external EEPROM.
UART & Serial
Custom protocol packet framing, telemetry streaming, RS232/RS485 Modbus RTU communication.
Timers & Clocks
On-delay (TON), off-delay (TOF), pulse timers (TP), and deterministic cyclic task schedulers.
Plug-in Device Library
Supported Sensors, Radios & Displays
Specific parts ship as device plug-ins, so a sensor is one node on the graph instead of a driver you write. Each plug-in compiles to ordinary C++ against the part’s real datasheet behavior — no runtime, no interpreter. The library grows with each release.
MaxBotix MB7850 / MB7854
Weather-resistant ultrasonic distance sensing for tank level, bin level, and proximity. Model and output units are set on the node; the reading arrives as a scaled value, not a raw count.
Graph Node
Semtech SX1262
Long-range sub-GHz packet radio for telemetry between sites with no network. Separate transmit and receive nodes drop straight onto the graph.
Graph Node
SSD1306 OLED
Small monochrome status display for local readouts on a panel or enclosure. Write text to an addressed line and column from the flow.
