Hello,
I am working on a temperature measurring device. Currently, I must do a communication with PC. UART is working great, I can send and receive any strings. Main goal is use a Modbus RTU protocole and I got stuck with this.
I am using a LPC241x demonstration project from freemodbus-v1.5.0 to convert for my program. I changed all VIC interrupts function to NVIC in portserial.c, porttimer.c and portevent.c. Also I modfied port.c and I used portmacro.h. After compilation i get no errors, but when I start Modbuss Poll, finally I am getting a nothing.
I have hope that someone help with this subject.
/* ----------------------- Start implementation -----------------------------*/
int
main( void )
{
eMBErrorCode eStatus;
eStatus = eMBInit( MB_RTU, 0x0A, 0, 38400, MB_PAR_EVEN );
/* Enable the Modbus Protocol Stack. */
eStatus = eMBEnable( );
for( ;; )
{
( void )eMBPoll( );
/* Here we simply count the number of poll cycles. */
usRegInputBuf[0]++;
}
}
