Subject: Serial MIDI driver for PL011 - as found on BCM2835 hardware
Date: Tue, 21 Oct 2014 10:40:59 +1100 [thread overview]
Message-ID: <1413848459.13334.9.camel@linux-host> (raw)
In-Reply-To: <1413847835.13334.8.camel@linux-host>
Hi,
I've written a driver for raw MIDI using the PL011. It is obviously
based on the snd-serial-u16550 module, with a couple of improvements:
- I've implemented a drain() callback.
- I've also implemented a half duplex mode based on a timer callback
which was necessary for reliable communication with my eMagic Unitor 8
hardware. (Testing with a serial link to other hardware shows that the
full duplex mode is also working.)
It can be found here:
https://github.com/kmtaylor/rpi_patches/blob/master/serial-pl011.c
If you think it should be included in the ALSA repository, please let me
know what to do next.
Regards,
Kim
