Adding WiFi support to Marlin with RAMP1.4

Hi misan,

Does your Marlin accept two Serial ports? Is there any modification to do?

jamesdanielv gives me a new marlin which accept two serial ports at same time!! Before changing my marlin, I want to know if there is modification to do to work with two serial ports, not espetially at the same timen but separately!!

If you just go to Marlin.h and change
#define MYSERIAL Serial

to

#define MYSERIAL Serial2

it will route serial comms to that other port
but Marlin codes its own serial handling routines.

I do not know what you need to have two serial ports working at once in Marlin but I reckon one touch-sensitive LCD panel was using a serial port and working with Marlin with a modified firmware, I would look for that.

Think you misan,

But don't want to change the MarlinSerial!! I want to let to communicate with my PC with USB. But I want to add an RFID module wich needs Serial Port, for that I need to add another one for it!!
I can add either SoftwareSerial or HardwareSerial!! As you said, I preferred HardwareSerial, it is much easier!! For that, I connect the RX2 and TX2 of Serial2 to my RFID module, and it works fine without Marlin!!

If I add Marlin, it said Serial2 was not declared in the scope!!
I want to let Myserial as a main serial "communication between host and Arduino mega 2560 with ramps 1.4", and another serial as secondary for communication with my RFID module!!

Please help!!

Hi misan,

Did you add a second serial port with MySERIAL of Marlin!! "MySerial is the main one and the another serial port is secondary"!!

I found new firmware which accepts two serial ports, it works very good!! You need to put your second device in port 2.

Good luck.

Hi pfinucan!
so how's your work? did it work fine?
