Processing arduino slave from raspberry pi

[glv]

Hello,

Are you connected to the correct serial port?

Try a simple example that just turns an LED on and off and watch the Rx lights on the Arduino side.

Processing to Arduino Serial Library Example

The SimpleWrite example in the Processing examples was not working on PCs I had available to me. The Arduino resets when establishing a serial connection. I added a delay(1000) to allow the Arduino to reset after serial connection to Processing and it now works. I modified the Processing setup() as follows: void setup() { size(200, 200); printArray(Serial.list()); //Added! List all the available serial ports String portName = Serial.list()[0]; myPort = new Serial(this, portNa…

I use serial pass through on receiving Arduino and a “USB-to-TTL serial adapter” to monitor communications between devices when doing development.
