Parsing Data From Serial Programming Arduino Forum I have a problem reading in serial data and assigning it to the fastled array. actually, it works fine most of the time but regularly, the number of bytes read by serial.readbytesuntil () does not match what is expected (180). These sketches are solutions for questions that commonly come up on the arduino forum. the sketches cover reading and parsing text input and writing delays and timers. the sketches use the robust arduino strings and safestring library.
Serial Communication Problem Programming Arduino Forum My problem is that when i want to parse my wheel speed command on my arduino i must parse from up to 4 separate bytes to int, for example s, 100, 100 makes my robot go backwards at full speed, but how do i parse this so i can call setspeed(left, right); with left and right equal to 100?. I just started working with arduino and in my project i am trying to achieve the comm between two arduino using hc 05 in master and slave mode respectively, i configured it all successfully. Explains how to reliably read data or commands from serial line in arduino without blocking the loop. Here is one way to do it. i am reposting your sketch because there were a few issues i had to fix in it to get it to work properly. serial.begin(9600); readdata(); . if(newdata){ outputbyte = 0;.

Hello, i am trying to parse motor control data that is being sent to the software serial port on an arduino uno. i have 2 arduinos talking over serial comm. arduino mega sending the following data:. Basically, i have 2 atmega328's connected to each other via the serial uart, one uc is measuring cell voltages of a lipo and spitting them out over serial, and the other is taking that data and displaying it on a lcd. I am trying to get a processing program to work with an arduino uno with three potentiometers hooked up to the arduino board. my problem is that my processing code only works intermittently. sometimes when i start it, it works fine, but mostly it shuts off after putting up the sketch window. I have no problem with the reading the serial port, parsing the data or sending data to the web server, but when i combine all of them i get "corrupted" data from time to time for example: my data ranges from 0 to 1023, and i got a couple of times something like 8830, which is over 1023.

Byte lowbyte = serial.read(); byte highbyte = serial.read(); the above attempts to read characters, even if none are available to be read. to learn how to do this correctly, i recommend to study the serial input basics tutorial.
