Hardware Questions / Re: Using USB serial port

Hi Mario,

Thanks for your help.  I got it working using gtkterm on my Linux box.  That allows me to control the RTS line, I think the driver on Windows was asserting RTS even if RTS/CTS was disabled.


Hardware Questions / Using USB serial port
« on: October 02, 2019, 05:36:08 PM »
I managed to build my Gecho Loopsynth kit OK, I'm enjoying playing with it and most things seem to be working but I haven't yet been able to get anything to come out of the USB serial port.

1) It seems like you have to remove batteries (I'm not using the rechargeable batter), switch the device on and then connect up the USB.  If I don't do this it goes into a mode where just the RST light is on (no RDY blink).

2) After powering it up by plugging in USB the RDY light is flashing.  I then start up my terminal emulator (I've tried PuTTY and TeraTerm).  When I open the COM port (in my case COM3) the RDY light stops flashing.  When I exit the terminal program it starts flashing again.  The device is not responding while RDY is not flashing so commands which should print on the serial port are not working.

3) The serial port is set to 115200 N81, is this correct? I have tried other settings without success.
