I tried the 2-channel Open Audio I2S objects as 32-bit but the output was distorted.? I might be missing something, but it appears to need more than just changing a define.? I found the Tympan

Hi Greg and Terrance -? I'm catching up on this.? And, not looking at the begin() end() issue, but just at the Quad I/O in F32.? I'm reading as I get time today, but here are a couple of thoughts.

As we know the documentation is a bit sparse.? You can get some of the designer's intent from looking at the examples.? I guess I need to go back and look at more of them. Beyond that and simply

I couldn't find the source, but I thought I read that the intent of the begin and end functions was to provide a quick, efficient way to start/stop the data flow.? The processing of the data,

It would seem that the interface should be consistent, where applicable, to all of the objects.? So that means any sort of complex data consuming function should have a begin() and end() function. An

Some OpenAudio library objects, AudioConvertxx for example, can't be disabled.? They continue to process as long they receive data.? It wouldn't be difficult to derive a class that could be

Hi Mark- I use a combination of switches and mixers because some things have to be both disabled and bypassed.? For example, the receiver equalizer can be active, or inactive and bypassed. So I do

Greg: I haven't been following closely along, but I thought it might be helpful to pass along the method that I have successfully employed in my TeensyMIDIPolySynth project (a MIDI-driven 3-voice,

I think there's a conflict. In the SDT.h header file around line 50 is the note: // ============ AFP 09-04-23 #include modified Si5351 library// == Modified Si library must be included in folder with

Hi Jack.? Thanks for the reply. Even though I have: I'm still getting: I forgot just how challenging it can be getting everything in the right places. . . Duane - K5CA

Duane: Those are function calls that the linker cannot find. This is usually caused by forgetting to #include some specific library. Look in the SDT.h header file, near the top, to see a list of the

Hi everyone.? Its been a LONG time since I've done any compiling, so I don't know how to go about understanding the meaning of : undefined reference to. . . Would someone be so kind to enlighten me?

So in the Teensy library you can do connect/disconnect.? But to do that, you have to use the name of the connection.? That's painful if you rearrange things and are forced to rename the connections.

As long as you stay within the OpenAudio library.? However, that library has some limitations.? For example, the AudioConnection_F32 class doesn't have a disconnect method and the connect method is

Hi Terrance, so at this point at least the I16 to F32 converters would not be required? If so, that would be a nice simplification that would be? worth it even without the I32 IO. -- 73 Greg KF5N

Porting the I16 quad I2S objects over to the OpenAudio library wasn't too hard if you ignore the configuration change needed for I32 input and output.? Here is the output from a PassThroughQuad_F32

Well I got my problem fixed. Watch the cable connections on the IDC . What I thought was pin 1 was not, check the boards. Made correct cable and it works. Tom AB9EK
