How to use Serial.readStringUntil() Function with Arduino. Learn Serial.readStringUntil() example code, reference, definition. readStringUntil() reads characters from the serial buffer into a String. Return The entire String read from the serial buffer,
myPort.bufferUntil('\\n'); background(80) 在下面的函数中,我们从串行端口接收数据并提取所需的数据,然后将其映射到图形的大小。 //extractingallrequiredvaluesofallthree axis:intl1=inString.indexOf("x=")+2; Stringtemp1=inString.substring(l1,l1+3); ...

Lastly, we have the loop, this will continually loop through until either a new program is uploaded or the Arduino is switched off. Inside the loop function, we have an if statement that is checking to see if there is data waiting in the serial buffer; “Serial.available“. In simple te...
