Hello everybody
I'm trying to migrate from MK4Duo to marlin 2.0.8.2 on my printer with Radds 1.5/Due using Visual Studio Code/PlatformIO and Auto Build Marlin

I modified Configuration.h and Configuration_adv.h with my parameters and in Auto Build Marlin I find 3 environments
DUE, DUE_USB and DUE_DEBUG
I tried DUE_USB and the compiler went to success.
But what is the difference between DUE and DUE_USB?

Thanks
Pietro

DUE has two ports
port 1) is via a usb serial chip
port 2) is directly connected to the cpu

if you wish to use port 2 you use DUE_USB

Thank you Dust
Is there any difference in performance?
Until now I connected Due via programming port, not the chip direct one without any problem.

Native usb port running CDC serial actually ignores baud rates and uploads as fast as it can (I think its 12mbs). but it way faster than a standard serial port limited to baudrates

Super! I'll try with native.
Thanks

COREXY 300x300x320 - Arduino due/RADDS 1.5 con MK4Duo 4.3.8

Hello I wasn't able to use native USB port with marlin
If I use DUE_USB then there is no way I can connect with my host (repetier or Octoprint)
With DUE (programming port) all is fine except the touch screen connected to AUX1
I Use a MKS TFT35 connected via serial to AUX1
Before I had a Nextion with MK4Duo (Marlinkimra) working fine

With MKS TFT35 I have problems
With
#define SERIAL_PORT 0
only the HOST connected via usb works

With
#define SERIAL_PORT 1
#define SERIAL_PORT_1 0
Touch display works but USB Host doesn't

with
#define SERIAL_PORT 0
#define SERIAL_PORT_1 1

USB Host works but TFT doesn't

Is there any way I can make both work?

Thanks

COREXY 300x300x320 - Arduino due/RADDS 1.5 con MK4Duo 4.3.8

you need serial_port -1 or serial_port_2 -1

Thanks Dust but I wasn't able to solve my problem

I made different combinations and conection don't work or I get conpile error

For example like this

#define SERIAL_PORT 0
//#define SERIAL_PORT_1 0
#define SERIAL_PORT_2 -1

I get

With MK4Duo I had this setup for nextion

#define SERIAL_PORT_1 0
#define BAUDRATE_1 115200
#define SERIAL_PORT_2 -2

#define MAX_CMD_SIZE 96

I tried with
//#define SERIAL_PORT 0
#define SERIAL_PORT_1 0
#define SERIAL_PORT_2 -1

And I get a long error...

please avoid mega-long code-inserts!!!

Hello
after many attempts I found this setup to work fine

#define SERIAL_PORT 0
//#define SERIAL_PORT_1 1
#define SERIAL_PORT_2 1

With this USB (Octoprint) and MKS TFT35 hooked on AUX1 are both working

COREXY 300x300x320 - Arduino due/RADDS 1.5 con MK4Duo 4.3.8

There is no such thing as SERIAL_PORT_1 in marlin

you must have SERIAL_PORT before you setup SERIAL_PORT_2
you must have SERIAL_PORT_2 before you setup SERIAL_PORT_3

you do get a error "error: #error "SERIAL_PORT must be defined." but it scrolls past and disappears

So SERIAL_PORT_1 could be a MarlinKimbra feature?

Anyway

#define SERIAL_PORT 0

#define SERIAL_PORT_2 1

in Configuration.h solved my problem..
Thanks

COREXY 300x300x320 - Arduino due/RADDS 1.5 con MK4Duo 4.3.8

Reflashed and now all works again.. Don't know why..

myself
Hello I'm here again
It seemed to be solved my problem but it's not..

With
#define SERIAL_PORT 0
and
#define SERIAL_PORT_2 1

the tft works but in read only mode

If I don't have Octoprint connected to the prithe tft don't report any data
If Octoprint is connected then TFT reports data but can't modify any of them or move anything

If I cut current off from 3d printer with octoprint still connected and tft off then Octoprint disconnect and report this:

SerialException: device reports readiness to read but returned no data (device disconnected or multiple access on port?)

RaspberryPi is connected to USB programming port, TFT to AUX1..

Again what happens?
