Hi everyone,
I am facing with a problem about changing DB9 port to USB port to adapt to new computer generation.
I download an application that has a Graphic user interface was written on Windows XP, use DB9 port connect to a board has a MAX232 IC to convert signal from RS232 to UART to communication with MCU with diagram:
PC -- DB9 cable -- RS232 to UART -- MCU.
My computer running windows 8, which does not have DB9 port, so I bought a board that convert USB to TTL (uart). So now my diagram is:
PC --- USB cable -- USB to TTL board --- MCU.
With my connection (using USB to TTL), I can not use the GUI to read or write signal because the GUI waiting for a "\r" ascii 13 or CR to parse data. I can confirm that because I can use a serial port software such as putty to type the command and communication with the board.
So my question is when I change RS232 to USB, will my signal be changed? if yes, could you suggest for me a solution?
Thank you so much!
