Currently, I am working on a project controlling Haptuator Mark II actuator (Link:http://tactilelabs.com/products/haptics/haptuator-mark-ii-v2/) using the Haptu-Amp-Quad driver (Link:http://tactilelabs.com/products/haptics/haptu-amp-quad/) with Arduino. I am using an SD shield to store audio(.wav) files and TMRpcm library (link:https://github.com/TMRh20/TMRpcm) to play the audio file through Arduino UNO Pin 9. It's working fine for one Haptuaotr Mark II actuator.
Now, I want to play multiple audio files from the Arduino board simultaneously and control 3 Haptuator Mark II correspondingly. My questions are as follows:
Is it possible to play more than one audio track using the TMRpcm library? Or I need to use other library or other Arduino boards to play 3 audio files differently and simultaneously?
I am able to control one LRA using Haptu-AMP-Quad diver. As per the specification, it is able to control 4 LRAs simultaneously. How to do that?
I am quite new in playing and handling audio files with Arduino. I am looking for your help. Thanks
