Blocking The Code With The Serial Print Function In Arduino Page 2 Accelstepper either uses a non blocking method where you are forced to repeat calling accell stepper function faster than each single step occurs to make sure it is a smooth step signal train or use a blocking function than might be interrupted by serial receiving. Since then i've figured out how to rewrite the code to be non blocking, by replacing the while loop with states, accumulating one byte at a time. i've written my first arduino library with this occasion: mindwave.
Blocking The Code With The Serial Print Function In Arduino Page 2 The basic arduino serial print functions are blocking, they watch the tx ready flag then load the next byte to transmit. this means if you send "hello world" the print function will block for as long as it take to load the uart to send 10 characters at your selected baud rate. You can pass flash memory based strings to serial.print() by wrapping them with f (). for example: serial.print(f("hello world")) to send data without conversion to its representation as characters, use serial.write (). Serial.read () is non blocking as well and will never wait. but the return value is an "integer", and in case the input buffer is empty, the return value is 1. so you can use serial.read () with an empty input buffer, if you read the return value into an integer and compare what you get. With a couple of exceptions, you should avoid using any serial methods in your loop () code and any code it calls. this is because almost all serial methods will block the rest of your loop () code from running so you will miss real world inputs and your outputs will be delayed.

Serial print works by starting a write using uart, then using interrupts to trigger another write when it is done writing the previous byte to the buffer. Sounds like a common baud rate disparity problem, but as i understand, i set my rate to 9600 (same as indicated by the serial monitor). have i made an error in the code, or missed some step to reproduce a serial.print ()?. This unremarkable example program increases a counter variable until it overflows, and while doing so, it outputs several debugging messages using the arduino’s built in serial interface. Using the hardware serial port (usart) is not blocking. you better tell which arduino you are using and post your sketch, so people can try it for you.
