Hello All,

I am trying to use MODSERIAL in one of my drivers and cant seem to get the attach to happen when setting up a callback to a member method

void Driver::uartRead(MODSERIAL_IRQ_INFO *) {
    _pc->putc(_uart.getc());
    rxLed =! rxLed;
}

Driver::Driver(PinName tx, PinName rx, Serial* pc) : _uart(tx, rx) {
    _pc = pc;
    
    _uart.baud(DEFAULT_BAUD);
    _uart.attach(this, &Driver::uartRead, MODSERIAL::RxIrq);

    // make sure we are not in config mode!
    _uart.printf("Q%s",LINE_END);
}

Which gives me the compile time error. "No instance of overloaded function "AjK::MODSERIAL::attach" matches the argument list (E304)

Since I am new to CPP I am having a hard time locating the issue or is it simply a bug in MODSERIAL?

Thanks for any pointers, Serge

Note, in the latest version the function prototype for the callback has changed from void funcname(void); to void funcname(MODSERIAL_IRQ_INFO *q);. See the docs and examples.

edit: if it's not working as expected, make sure you are using the latest library.

Got it ...

Actually its connect and not attach in this case ... my bad.

Thanks, Serge

I think this is what you are looking for:-

void Driver::uartRead(MODSERIAL_IRQ_INFO *q) {
    MODSERIAL *s = q->serial;
    s->putc(_uart.getc());
    rxLed =! rxLed;
}

// ** OR **

void Driver::uartRead(MODSERIAL_IRQ_INFO *q) { // NOTE, you still need the "q" even if not used.
    _pc->putc(_uart.getc());
    rxLed =! rxLed;
}


Driver::Driver(PinName tx, PinName rx, Serial* pc) : _uart(tx, rx) {
    _pc = pc;
    
    _uart.baud(DEFAULT_BAUD);
    _uart.attach(this, &Driver::uartRead, MODSERIAL::RxIrq);

    // make sure we are not in config mode!
    _uart.printf("Q%s",LINE_END);
}

Oh, connect() is just supposed to be an alias of attach(). Maybe I missed something when adding the new callback system. I'll have a look.

Fixed in v1.21 (just released). Thx.

Thx Andy,

Confirmed ok.

Right, the documentation should be fixed to match the library - it still specifies a void parameter for the callback function.

Hello Andy,

I am getting compiler error on lines 61 and 68 in INIT.cpp:

"no instance of overloaded function "mbed::Serial::attach" matches the argument list" in file "MODSERIALINIT.cpp", Line: 61, Col: 66

I am using v27 of MOSERIAL and v53 of mbed.lib

thanks, ...kevin

This was more a very old topic regarding a problem, see the cookbook page: http://mbed.org/cookbook/MODSERIAL (but yeah you were the first to report this one).
