Re: Audio Hat Hangup

 

Ah Haw now that makes sense.?
I miss the old days of paper catalogs, I was looking for machined pin headers and got no where.?
I know they are out there, was easier to flip thru catalog.?
I have some old ones maybe I can find part numbers and search with those.

Re: Audio Hat Hangup

 

To All,
?
I also was having similar problems with audio hat and teensy pin connections. I found that the long pin headers have a pin that is flat .015 thick, were as the short pin headers had a .025 square shape pin. When inserting the long pin header into the short pin headers the flat pin was not making a good connection.

Bill,
Did you get my note about changes to the component values for the SSB Exciter chain on the RF board? If not , I will re-send it.? These changes enable the flat response and lower adjacent channel images.

  1. Removed all of the MF stuff but left the jumpers to CLK0 and CLK1 so that they could be driven from something else or checked with no load.? MF done in software now.
  2. Added a cap C74 at the junction of L7 and Y1 VDD. ??This was inadvertently missed in all versions.? If anything, cleans up the noise floor a little.
  3. Changed U106 to a AD8599, and U107 to a OPA2209 (better S/N by at least 20 db). ??Better parts, but the previous parts will work (Identical footprints) in a pinch too with higher S/N.

Actually... My K3 does exactly that... one USB cable that everything flows over.... digital/CAT and Audio. I do have the schematics for that board so I can see how it's done from a hardware standpoint... but then there is the software... and the extra processing.

Or we could use one of the traditional serial ports built into the Teensy hardware.
There are eight of them. But looking at the Main Board schematic, I don't see much in the way of unused pins.

All,

I have been working on CAT ( remote control ) for the T41. I
re-architected it to a data-driven approach that is much cleaner and

will be easier to maintain and expand.

I have the basics running: read & set the frequency, read & set the
volume and mike gain, set the operation mode, make it transmit. It
is an emulation of the Kenwood TS-2000. There is a LOT of stuff that
we don't do yet.

I have given the code to Jack. I hope it winds up in the permanent
archive.

Right now, I am getting nowhere fast with the next step: piping
audio over the USB. With that, we would be able to run digital modes
with

nothing but a USB cable between the radio and a PC.

USB function is selected by the "USB Type" pulldown at the Arduino

IDE. There are various combinations of functions, but not the one
that we need: two serial ports, plus audio. One serial port for the
teensy uploads & Serial printf()s, a second serial port for CAT
control, and an audio port.

The code that implements these USB functionalities is buried in the
Teensy "core" - the actual TeensyDuino code. In my system this is
at:
c/Users/Jerry/AppData/Local/Arduino15/packages/teensy/hardware/avr/1.59.0/cores/teensy4.

The definitions of the USB choices are in usb_desc.h. It's basically
a big array of #define's. Lots of sets of #defines, each set in an
#elif section.

ANYWAY, I hijacked the "USB_TRIPLE_AUDIO" section and replaced the
third serial port with audio.

Big fail. It compiles and loads, but then the "composite USB device"
does not start, there not only no audio, there are no serial ports.

Without serial ports, I have to hit the button on the Teensy to
upload new code to it. I'm at a bit of a loss as to how to
troubleshoot it.
USB is pretty complicated...and no debugger. Can't even do debug
printf's. One possibility would be to hook up a not-USB serial
interface to a couple of teensy pins. Or do what I did once upon a
time...find an unused I/O pin and have it emit morse code.

The Teensy is limited to 8 USB "Endpoints". That limits the number
of USB devices you can have active. Two serial ports plus audio
maxes it out. Which is too bad. There's also a simulated disk
drive, which could come in handy.

Any USB experts out there?

That board should be here in the next day or two.? I will mount it in the place formerly occupied by the 24 volt boost module.
The primary reason for adding the hub is because I am adding a USB audio codec to the T41-2.
I did a few experiments with the TeensyDuino Audio library, which has a USB audio object.? It works, but . . .
The problem is that it is inflexible.? 44.1ksps only.? Plus sucking up more precious RAM.
I'm solving the problem with hardware.? Will see how it goes soon.? The experiments continue . . .

Re: CAT

 

Since those native serial ports are all at digital levels (0 & 3.3VDC, & inverted from normal RS-232), you'd essentially need any of a variety of common TTL-to-RS232 level convertor chips in order to connect any of those ports to a controlling PC.

No cables attached except for Ribbon cables and rf coax. Nothing attached to Audio Hat.

I think I will start on new Main board (don't believe I could get hearers off even with my vacuum sucker) and use machine pin headers.

I used those on critical projects that needed IC's replaced often.

Here¡¯s another thing.? There are other ways to interface USB to the Teensy if you need more USB hardware.? The FT201, FT233, FT311, FT2222 are all devices that sit on one of the I2C busses as a USB translation device.? There appear to be Arduino libraries for all of these devices. ?

Subject: [SoftwareControlledHamRadio] CAT

All,

I have been working on CAT ( remote control ) for the T41. I
re-architected it to a data-driven approach that is much cleaner and will be
easier to maintain and expand.

I have the basics running: read & set the frequency, read & set the
volume and mike gain, set the operation mode, make it transmit. It is an
emulation of the Kenwood TS-2000. There is a LOT of stuff that we don't do
yet.

I have given the code to Jack. I hope it winds up in the permanent
archive.

Right now, I am getting nowhere fast with the next step: piping audio
over the USB. With that, we would be able to run digital modes with nothing
but a USB cable between the radio and a PC.

USB function is selected by the "USB Type" pulldown at the Arduino IDE.
There are various combinations of functions, but not the one that we need:
two serial ports, plus audio. One serial port for the teensy uploads &
Serial printf()s, a second serial port for CAT control, and an audio port.

The code that implements these USB functionalities is buried in the
Teensy "core" - the actual TeensyDuino code. In my system this is
at:
c/Users/Jerry/AppData/Local/Arduino15/packages/teensy/hardware/avr/1.59.0/co
res/teensy4.

The definitions of the USB choices are in usb_desc.h. It's basically a big
array of #define's. Lots of sets of #defines, each set in an #elif section.

ANYWAY, I hijacked the "USB_TRIPLE_AUDIO" section and replaced the third
