Problems with serial interrupts?

Hi, I want to use serial interrupts.

If I use this code, it always shows an error:

device.attach(&Rx_interrupt, Serial::RxIrq);

ERROR:

"class "mbed::Serial" has no member "RxIrq"" in file "/main.cpp", Line: 34, Col: 39

I also used this Demo Code: https://mbed.org/cookbook/Serial-Interrupts

but it shows the same error message.

What's wrong with my compiler :D?

Hi Franziska, as part of the complete refactoring of the mbed library we moved the parameter type definitions from the C++ API to the C API. The missing interrupt enum has moved from Serial.h to serial_api.h: serial_api.h

This is a simple example for the new API:

#include "mbed.h"
 
DigitalOut led1(LED1);
DigitalOut led2(LED2);
 
Serial computer(USBTX, USBRX);
 
void txCallback() {
    led1 = !led1;
}
 
void rxCallback() {
    led2 = !led2;
    computer.putc(computer.getc());
}
 
int main() {
    printf("start\n");
    computer.attach(&txCallback, TxIrq);
    computer.attach(&rxCallback, RxIrq);
    while (true) {
        wait(1);
    }
}

HTH, Emilio

Accepted Answer

missing of object in attach funaction. Corrected code.

  1. include "mbed.h"

DigitalOut led1(LED1); DigitalOut led2(LED2);

Serial computer(p9, p10);

void txCallback() { led1 = !led1; }

void rxCallback() { led2 = !led2; computer.putc(computer.getc()); }

int main() { printf("start\n"); computer.attach(&txCallback, computer.TxIrq); computer.attach(&rxCallback, computer.RxIrq); while (true) { wait(1); } }
