If you aren’t working directly at the command line, then you will need to get the Arduino (or other) IDE to add that flag when it forms the compilation command lines. Injecting Definitions at Compile TimeĪdding a flag to the compile command line can #define a macro constant for that compilation, e.g.

It may be easier and more effective in the long term to avoid printing too much at once, so you can do better at keeping up with the serial input. In any case, you probably don’t need to increase the value for these processors in recent versions of the libraries. The comments say this is the size for the receive buffer, but I can’t find a separate spec for transmit, so I suspect it is for both. For the Adafruit SAMD products look in packages/adafruit/hardware/samd/1.5.9/cores/arduino/RingBuffer.h where it’s also 256. Users//Library/Arduino15/packages/arduino/hardware/samd/1.8.4/cores/arduino/RingBuffer.h for SERIAL_BUFFER_SIZE which is set to 256 unless previously defined, e.g.
For the SAMD family of processors like the M0 look to e.g. Bigger is better unless you are pushing up against memory limits. The standard values vary with the port number and are under 64. SERIAL1_TX_BUFFER_SIZE and SERIAL1_RX_BUFFER_SIZE are defined as a number of bytes unless they have been previously defined, e.g. #How files wind up in the hidden library folder on mac code
For the Teensy 3.X family of processors, the library code is part of the application contents Arduino/Contents/Java/hardware/teensy/avr/cores/teens圓/serial1.c etc. The standard values of 16 and 64 are tiny and you need to program accordingly, getting back to read new characters often, and not trying to send a lot of data at once unless you want to wait. For the UNO and other AVR processors, the library code is part of the application contents Arduino/Contents/Java/hardware/arduino/avr/cores/arduino/HardwareSerial.h where SERIAL_TX_BUFFER_SIZE and SERIAL_RX_BUFFER_SIZE are defined as a number of bytes unless they have been previously defined, e.g. Increasing the buffer sizes will eat up memory that is precious on an UNO, but much more available on other processors. Getting a bigger buffer seems to be a moving target as the code base for different processors evolves. If your serial communications seem to be losing characters, you probably need a bigger buffer. That delay, in turn may prevent the sketch from reading the incoming data on the receive side of the serial port before its buffer overflows. A call to Serial.print() will wait until it finishes, or times out, which can delay the sketch if the thing being printed requires more characters than will fit in the buffer. Increasing Serial Buffer SizesĪll sorts of problems can arise from not having a large enough buffer for serial ports, both incoming and outgoing. Teensyduino also stores the hardware files inside the application package. The IDE application itself contains the basics for the UNO and you’ll have to right click and select show contents to see what’s inside the package. #How files wind up in the hidden library folder on mac mac
On a Mac most wind up in the /Users//Library/Arduino15/packages/ folder, which is hidden and may be hard to find. Provides a lot of information on how boards get installed and where.
