MIDI USB host examples

jking1 — Tue, 21 Jun 2022 09:16:53 GMT

Has anyone got any example code or project to implement a USB MIDI host on, for example, the LPC54628?

In the SDK there are example projects for HID, MSD, CDC etc. but nothing for MIDI.

I'm aware of nxpUSBlib from around 2016, but I'm looking for something that is based on the code structure of the current SDK host examples so that I can efficiently drop in support for MIDI along side other device classes.

Thanks

Hi jking1

Unfortunately our SDK for LPC54xxx doesn't integrate USB MIDI samples.

I'm well aware that the LPC54xxx does not have any midi host examples. I'm hoping that the wider community might be able to provide some insight or assistance.

Is there a reason that midi is not covered in the current SDKs?

Regards

What demo code is included in SDK is a market decision.

As I know lpcopen for LPC176x includes USB MIDI host code. You can take a look at MIDIClassHost.c/h file. However SDK doesn't support it.

If any 3rd party has demo for it, welcome to share here.
