AMBE GPIO board #analog_bridge


HL5KY
 

Thank you for the great work of DVSwitch. I am trying to hook up my AMBE GPIO board which was made in Japan and similar to DV3000 GPIO board. It was working ok for AMBE server on RPI3B+ with the following setup:

          device port : /dev/ttyAMA0

          baudrate : 460800

 

It doesn't work for DVSwitch with the following setup(s) in Analog_Bridge.ini:

          device port : /dev/ttyAMA0

          baudrate : 460800   or   230400 (AMBEtest4.py showed this baudrate)

          serial : true

 

Interestingly, I get the different baudrate from the AMBEtest4.py on RPI3B+

Here is the result:

 

          Setting serial port

          Serial port parameters:

          Port name:      /dev/ttyAMA0

          Baudrate:       230400

          Byte size:      8

          Parity:         N

          Stop bits:      1

          Xon Xoff:       False

          RTS/CTS:        False

          DST/DTR:        False

Questions:

1. Does DVSwitch only support USB serial device ?

 

2. If it supports GPIO serial, is there other way of setup for GPIO device on Analog_Bridge.ini ?
