update to get fix to MIDI sys ex

[mzero]

Adafruit cores that incorporate this variant of the TinyUSB stack have a serious bug that renders it impossible to send MIDI SysEx messages.

The bug was fixed in TinyUSB back in september... but must get pulled in here first, then pulled into relevant cores, to create working base for users' sketches.

• The original bug report is here: SysEx messages are improperly sent hathach/tinyusb#511
• And the pull request for the fix: Fix a bug in writing SysEx messages. hathach/tinyusb#512
• The fix was merged into TinyUSB on Sept 22nd here:
  hathach/tinyusb@8b2c822#diff-716fd87d6209145578ccbd94da446baf17157c5d7c7fd1e6ab1deae10ba5328d

I'm hoping that see the fixed TinyUSB can be merged here... so that we can eventually have cores that work for sending MIDI Sys Ex.

Hi, would you mind telling me which board you are using samd or nrf ?

[mzero]

I'm using the SAMD core - https://github.com/adafruit/ArduinoCore-samd

I looks like the code in ArduinoCore-samd is getting ready for the next release... it would be great if we could get this in there.

I am off for vacation. Will be back after a week. Will check it out later then

[hathach]

Though you don't gave to worry about catching up with release. We do release whenever it needs

This bug, now 6 months fixed in the tinyusb repo, is still here. And because it is still here, it is still in the cores for Adafruit boards. Hence, Adafruit board users still have this bad bug, which means they cannot send SysEx messages.

Can we get the source code here refreshed from tinyusb?

[hathach]

thank for reminding this issue, there is lots of changes in the tinyusb stack. Sync it up will also need to re-test and bump up both the SAMD and nRF cores which involved mostly testing. We have been kept busy with lots of other works, though I will try my best to re-test, sync up and release these asap.

should be fixed by after release 1.0.0
