TÓM TẮT
Electric guitar pedal is a device that alters how an e-guitar sound. It modifies the signal coming from the electric guitar (which is just a wooden guitar with a pickup), adding “effects” that change the way it sounds in order to add interest or create more impact. This paper describes the implementation of an electric guitar pedal device based on Arm Cortex-A9 processor, using mbed OS API. This device has the looper mode that allows users to record and play back in a loop. It also has the tuner mode that helps users to tune the guitar correctly. Finally, we have built a prototype of an electric guitar pedal device using Renesas’s GR-PEACH boards for demonstrating research results.
