Hi,
I have a one question. I use the modbus serial for comunication. It is script:
*#include <ModbusSlave.h>
/ First step MBS: create an instance /
ModbusSlave mbs;
/ slave registers */
enum {
MB_CTRL, /* Led control on, off or blink /
MB_TIME, / blink time in milliseconds /
MB_CNT, / count the number of blinks /
MB_REGS / total number of registers on slave */
};
int regs[MB_REGS];
int ledPin = 13;
void setup()
{
/* the Modbus slave configuration parameters /
const unsigned char SLAVE = 1;
const long BAUD = 9600;
const char PARITY = 'n';
const char TXENPIN = 1;
/ Second step MBS: configure */
mbs.configure(SLAVE,BAUD,PARITY,TXENPIN);
pinMode(ledPin, OUTPUT);
}
void loop()
{
/* Third and las step MBS: update in loop*/
mbs.update(regs, MB_REGS);
if(regs[MB_CTRL]==1)
{
digitalWrite(ledPin,1);
}
else{
digitalWrite(ledPin,0);
}
}**
But i want a blink effect in led and i modified the script:
if(regs[MB_CTRL]==1)
{
digitalWrite(ledPin,1);
delay(3000);
digitalWrite(ledPin,0);
delay(3000);
}
else{
digitalWrite(ledPin,0);
}
}
Well, when i set the bit 1, the led blink but it don't enter in the else.
Anyone had the same problem with supervisory and script?
