Re: Xcat-2022 proposal

 

Hi Dave,

I would rather NOT use the USB serial port to simplify the wiring and to minimize high speed signals inside of the radio.? USB would be used to flash the board with the initial?flash image.??

Possible wiring options:
1. Route 3.3V Rxd, Txd via unused control cable pins or just drill a hole for a 3 pin cable.
2. Route 5V Doug Hall clock and data line via unused control cable pins or just drill a hole for a 3 pin cable.

For the Xcat-9000 another option would be to use SB9600 for communications and attach the Xcat2022 to the SB9600 bus internally.? ?No need to find unused control?cable poins or drill holes for a new cable.? I'm starting to like this...

Testng the Doug Hall interface should be easy even w/o a radio.? You would need one of your controllers connected to the new board and the original?XCat PC control program or a successor.? Frequencies set via the Doug Hall interface can be read back over CI-V.? If they are correct then we're good to go.

Hi Skip,

I wrote the Doug Hall RBI-1 firmware support for the S-COM 7K controller.? I still get requests for RBI support on the S-COM 7330 -- I'm in the middle of implementing that now.? I have an RBI and radios to test with.? I don't have an Xcat and radio, though I'm sure we can fix that.

Will the USB connector on the Pico replace the serial port?

BTW, there's both a MicroPython (the original) and CircuitPython (supported by Adafruit).

73,

Good morning Dave!

Thank you for volunteering !!!?

The C64 Rom project is very close to what we need, you can find the schematic here: .?

The schematic for the original Xcat is here:?/g/xcat/files/XCat%20files/xcat-schematic.PDF.?

I'll get started on generating a new schematic.

So questions for all that are interested:

Do we still need RS232 level converters for the serial port?? My opinion is NO, 3v3 levels and an FTDI USB cable for a PC connection.

Do we still need Doug Hall support?? If so we will need level converters for that interface.? Personally I'd like to drop it, I don't have any way to test it.

What did we miss on the original Xcat that we can add now?? One request I remember is support for 64 modes, that should be no problem for the new board.

My idea for the Xcat 2022 is for it to be a completely open source project including the firmware and PCB.?

If someone wants to build one themselves, great!

If someone wants to kit it up and sell a kit then have at it (it won't be me!).

If someone wants to sell built and tested boards more power to them (that wont be me either!).
