SoftwareSerial problem

Using Arduino Programming Questions
#1

I’ve used the IDE quite a bit, but not lately. I just upgraded to 1.8.0.

I’m trying to control an LCD display, using SoftwareSerial. The code below is a stripped-down version that shows the problem.

#include <SoftwareSerial.h>

SoftwareSerial    sw_serial = SoftwareSerial(-1, 8);

void
setup()
{
    pinMode (8, OUTPUT);
}

void
loop()
{
    sw_serial.listen();
    sw_serial.write((uint8_t) 0xfe);
    sw_serial.write((uint8_t) 0x01);
}

When I verify this, I get:

In function ‘void loop()’:
error: ‘class SoftwareSerial’ has no member named 'listen

I’ve tried various board settings in the IDE, no change.

I just got it fixed: it was bringing up an older version of the IDE when I clicked on a sketch. I reinstalled one more time, and now it's working.

Thanks for checking it out.
