Re: Codec & ADC's
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

Re: Codec & ADC's
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

Re: Codec & ADC's
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,

Re: Undefined reference to. . . When compiling
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

Re: Undefined reference to. . . When compiling
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

Undefined reference to. . . When compiling
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?

Re: Codec & ADC's
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.

Re: Codec & ADC's
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

Re: Codec & ADC's
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

Re: Codec & ADC's
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

Re: BPF and Teensy Problem
Well they arrived, but are shy of the specified pin dimensions. Instead of 0.40mm they are 0.34 mm. At least they are the full row, so I don't need to patch two together. John K1JO

Re: BPF and Teensy Problem
I see he sells header pins with different colors. I find these really handy for identifying test points on a board (e.g., red for voltage TPs, yellow for general purpose TP's, etc.) Jack, W8TEE
