When do you use the Arduino’s Serial. Tooth module using the software serial calls on an Arduino UNO and I have found. Read the serial and write to. Write() Description. Writes binary data to the serial port. This data is sent as a byte or series of bytes; to send the characters representing the digits of. In AVR, there is a write(int) overloaded method, that match exactly with write(0), so the compiler doesn't complain. On the other side, 101 for example has only a write(uint8_t) method, so the compiler doesn't know if he should use that, or write(const char*), because both require a type conversion. I am not so sure it is a good idea to hide the fact that write takes only raw bytes by overloading it in the AVR libraries, but i guess that it was done to keep people from complaining about the ambiguous overload;-). Or just do in SAM what is done in AVR and add the write(int) et al methods to HardwareSerial.h. Then you have to do it in SoftwareSerial also (and other Print derived classes, if any), for consistency. It could be in Print, but then i guess that the compiler won't honour the inline (to be checked), and that we don't want another overhead on such a low level function. Tyrone biggums. BTW, a workaround to this particular problem is to do Serial.write(byte(0)) (which is also more elegant IMO). That's of course the simplest solution, then the write overloads should be suppressed from HardwareSerial for consistency. Mutual funds combine money from many investors to invest in a portfolio of stocks. What is a 'Dividend Reinvestment Plan - DRIP' A dividend reinvestment plan. Stocks with drip program. Free Software Serial NoOr just do in SAM what is done in AVR and add the write(int) et al methods to HardwareSerial.h.
