Description
This reference design provides a way of generating alarms similar to as described in the IEC60601-1-8 standard for medical devices. The critical timing parameters are programmable through firmware. All parameters, including pulse width, pulse rate, internal frequency, pulse rise time, volume control, and priority, are controlled using firmware. The analog envelope is generated by a combination of the MSP430FR2311 and analog circuitry.
Features
- Provides a mechanism to generate auditory alarm tones with programmable timing and frequency
- Outputs low-, medium-, and high-priority alarms with software-adjustable rise/fall time, pulse duration, pulse spacing, and burst spacing
- Adjustable volume control
- Powered by USB port on PC
- Outputs 8 different alarm melodies
- Coincidence detector confirms if speaker is outputting correct sound
