All the serial commands for the ezb can be found in...

EZ_Builder.EZBManager.EZB[0].Uart

@DJ

Thanks much, that helps but there is nothing like having a completed and working example to look over and learn from. The serial toolbox covers alot more than what was included in your awesome tutorial on plugins...Rick.

@DJ

Also curious as to how the serial plugin handles the arduino side of things...Rick.

Only to give a little bit of context. Rick sent me an email requesting some help to integrate an Arduino with ARC.

I will start by saying that: Arduino is not EZ you can easily open the IDE, copy paste some code, compile, flash and run.

But if you need to dig in you will need to know C/C++ language, how the libraries work, board specific details, code optimization, troubleshooting without breakpoints, limited memory, limited resources, interrupts, timers etc, etc.

Hardware used:

1. Arduino UNO
2. EZB V4

Arduino:

Power = USB/Cable Pins 0 - RX - Grey wire 1 - TX - Purple wire 3 - Red wire 5 - Green wire 9 - Blue wire GND - Black wire 5V - Orange wire

RGB Led (Common Cathode)

Red Led - Red wire Green Led - Green wire Blue Led - Blue wire 5v - Orange wire

EZB

Power = 7.5v Power supply Uart 0 - RX - Purple wire Uart 0 - TX - Grey wire Uart 0 - GND - Black wire (Common Ground)

Arduino Code:

1. Libraries To make the process less complicated, i created an Arduino library called SerialCommands you can grab from here:

https://github.com/ppedro74/Arduino-SerialCommands

Please download the and install the arduino library.

i opened a ticket to publish the library via Arduino IDE tool, later you will be able to search and install automatically via Arduino IDE.

2. Example project: https://github.com/ppedro74/ArduinoPlayground/blob/master/TestSerialCommands/TestSerialCommands.ino

Compile and flash!

Note: When flashing an Arduino with a single Serial Port (Atmega328, Atmega168) disconnect the RX/TX cables (EZB side) to avoid interferences.

Test Arduino Code:

Open the Arduino Serial Console:

Blue Note: When sending serial commands the existent code expects the CR & LF to end a line

Red Note: 57600 bps is intentional ! All micro-controllers have different clocks, when working with serial communications both sides (RX / TX) agree on a specific BaudRate / Clock, unfortunately 115200 bps @ atmega328 is not 115200. So let's use 57600.

The arduino code (relevant part)

SerialCommand cmd_read_analog_("READ_ANALOG", cmd_read_analog);
SerialCommand cmd_set_led_("SET_LED", cmd_set_led);
SerialCommand cmd_start_push_("START_PUSH", cmd_start_push);
SerialCommand cmd_stop_push_("STOP_PUSH", cmd_stop_push);

accepts the following commands: READ_ANALOG, SET_LED, START_PUSH, STOP_PUSH

some examples:

//reads analog port 0
READ_ANALOG 0

//read analog port 1
READ_ANALOG 1

//read analog port 2
READ_ANALOG 2

//set red led (ON) RGB Led (Common Cathod/255-Off, 0-ON)
SET_LED 0 red

//set red and green led (OFF) 
SET_LED 255 red green

//set red and blue led (HALF bright) 
SET_LED 128 red blue

//request ping push messages every 1000 ms
START_PUSH 0 1000

//request analog push messages every 3000 ms
START_PUSH 1 3000

//stop ping push messages
STOP_PUSH 0

//stop analog push messages
STOP_PUSH 1

The above commands are examples how:

1. Set actions (SET_LED) (Note: multiple parameters example)
2. Read Values (READ_ANALOG)
3. Monitoring values / Pushing results (START_PUSH / STOP_PUSH)

After submitting the above commands:

Note: After the START_PUSH the arduino code starts pushing messages to the console. This can be modified to instruct the Arduino to perform some action or monitor a sensor and report the values back with a specific frequency or a specific trigger, all depends the code logic.
