Baud Rate Calculator
Actual baud, error rate, and character and bit timing.
Timer Calculator
Allows settting of prescaler, desired timing (in millseconds, microseconds, or Hertz), whether computing base rate or toggled [double frequency], showing compare values, actual rate, and error percentage, and timer overflow periods.
TWI Calculator
Computes TWI (I2C) frequencies based on register values as well as computing register values based on desired frequency.
Watchdog Calculator
Computes times for number of 128kHz watchdog cycles.
FMUL Calculator
Computes AVR fractional multiplications.
32-bit Number Calculator
Converts between decimal (integer and floating point), hexadecimal integers, and IEEE-754 floating point. Can switch between little and big endian formatting.
