Serial plotter over bluetooth

I got that the delay is due to processing refresh rate that should be 30 fps by default.

Default is 60 fps:

draw() / Reference

frameRate() / Reference

In my example I used serialEvent():

You can “buffer” received data into an array in serialEvent():

• use a counter\pointer to element of array
• set a flag to indicate when data is ready
• be sure to reset counter\pointer to element in array

In draw();

• when flag is set you can use that data in draw()
• be sure to reset flag

It will take some effort to work through and understand this; work through it slowly and build on that.

There are many ways to handle serial data; you can also send a buffer all at once from Arduino:

Problem with the use of several sensors, Arduino / Processing

Hello, Some code I wrote to explore Arduino transmitting data to Processing. It runs fine at a BAUD rate of 1000000. I use an Arduino MEGA 2560 R3.

Arduino Code

// Serial Incoming Test (Arduino Tx) // v1.0.0 // GLV 2020-02-29 long count; void setup() { //Serial.begin(9600); Serial.begin(1000000); delay(1000); Serial.print('\n'); //same as Serial.println() Serial.print("incoming"); Serial.print('\n'); //same as Serial.println() } void loop() …
