G400D com ports


#1

I am trying to get a G400D working in a custom board that used the ChipworkX and I can’t get one of the COM ports to work.

On the datasheet for the G400D COM4 is on pins 200 and 167

In code I could not get COM4 to work and ended up using COM3 to get those pins to work.

The document is wrong in this case.

@ Dave McLaughlin - We were unable to reproduce the issue. What framework version are you using?


#3

Also, COM port numbers are different between chipworkx and g400. Maybe this where the confusion started.

Sorry for the delay. Was out of town.

My original posting may have sounded a little strange as I was referring to both COM3 and COM4 as if this was in reference to the hardware but is actually a mix. Let me try again.

@ James
I am running this with 4.3 now. The custom board is wired for what would physically be COM4 (pins 200 and 167) but in the code I have had to use “COM3” as the string passed to the serial port when I create it so I can communicate with the device. If I use the string “COM4” in the code, there is no communications.

@ Gus
I already changed all the pin numbers and COM PORT names to suit the G400D. It was only COM4 that didn’t work until I change the code to use COM3.

@ Dave McLaughlin - What version of the G400D do you have?

I am using a V1.3 board.
