THEY
AREN'T MEANT TO EVER CHANGE!

This header contains configuration parameters and a few #defines for the Hummingbird FCU.

SENSOR I2C BUS

This is the Teensy 4.1 's I2C bus that the FXOS8700 accelerometer/compass, FXAS21002 gyro, GPS compass, and BMP388 barometer/temperature sensor are connected to. Found in hummingbird_config.h

◆ TELEM_PORT

#define TELEM_PORT Serial8

TELEMETRY SERIAL/UART BUS

UART/serial port that the XBee radio is connected to. Found in hummingbird_config.h

◆ VCC_PIN

#define VCC_PIN 22

VCC INPUT VOLTAGE ANALOG PIN

This is the pin that is connected to the HFCU's voltage divider circuit to read input voltage.

Variable Documentation

◆ FLOAT_PREC_ZERO

constexpr float FLOAT_PREC_ZERO = 1e-7F

constexpr

Define floating point precision for floats close to zero.

These parameters aretypically used to check if a number is close to zero to prevent divide by zero errors. Found in hummingbird_config.h

◆ FLOAT_PREC_ZERO_NOISY

constexpr float FLOAT_PREC_ZERO_NOISY = 1e-5F
