How can I set up a communication from Medusa mini via RS232?

Post by Keniey » Wed Apr 12, 2017 6:07 pm

I'm trying to set up a communication from Medusa mini to a Gadgeteer Board via RS232 but I have problems to write to RS232 on the Medusa Mini (Arduino newbie).

Code: Select all

#include <Wire.h>
#include <SPI.h>
#include <Gadgeteering.h>
#include <Mainboards/FEZMedusaMini.h>
#include <Modules/RS232.h>

using namespace gadgeteering;
using namespace gadgeteering::mainboards;
using namespace gadgeteering::modules;

fez_medusa_mini board;
rs_232* my_Rs232;

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  my_Rs232 = new rs_232(2);
  my_Rs232.write("Hello World");
}
I get the the errormessage:
Arduino: 1.6.5 (Windows 8.1), Platine: "FEZ Medusa"

Medusa_Mini_RS232_Test.ino: In function 'void setup()':
Medusa_Mini_RS232_Test:39: error: request for member 'write' in 'my_Rs232', which is of pointer type 'gadgeteering::modules::rs_232*' (maybe you meant to use '->' ?)
request for member 'write' in 'my_Rs232', which is of pointer type 'gadgeteering::modules::rs_232*' (maybe you meant to use '->' ?)

How can the string be sent?
Another question: how can the RS232 module be configurated different from the defaults:

Thanks in advance, Keniey

Is there a way to select the stop bits and parity?
I just remember it from my modem days from the 80's. There are more than one type of RS232. It also depends on how you set the parity and stop bits.
