Autonomous Transmission of Analog Sensor Data on an ARINC 429 bus without an MCU
In today’s complex aircraft, sensors are everywhere. Gathering data is critical. Typically, analog transducer measurements are passed through an ADC, manipulated by a microcontroller, and passed to a communication protocol device for transmission on an avionics data bus. The microcontroller requires code, which increases design time, cost and certification complexity. This paper introduces a new device which provides a way to autonomously transmit sensor data over an ARINC 429 avionics data bus and completely eliminate the requirement for an MCU or software.
