Read from MIDI UART with Alsa drivers

Hi,
I’ve installed the ALSA drivers (for my SBLive!).
Everything works well. Now I’m trying to program a Photon App wich will do
some stuff with my MidiUART. I can compile my program, which will get the
name of the SBLive! and the midiUART (that part works perfect, I see the
names in a PtLabel) But when I want to read from the UART’s port, I get an
error : operation not permitted.
Does anyone have experience with this?

Sorry, I saw I attached the wrong file… :frowning:
When I’m at home I will post the right one…

I think I found the problem (yeh, had to do it on my own, nobody
is helping me…:frowning: ) There was a “;” after an if statement. I tested it
with writing to the UART, and it WORKED !!! :slight_smile:
I’ll test with reading tonight (when I’m at home)

bye for now…
