Self-defined toolhead example

Introduction

This example is for self-defined toolhead, which develops by using arduino pro mini 3.3v version, you can use any compatible arduino board you like.

There are files to interact with FluxSDK:

• command.h - command class declaration
• commnad.cpp - command class implement
• selfdefined_toolhead_example.ino - arduino program entrypoint

Quick start

• Download the arduino IDE ,select arduino pro mini board and serialport ,click "Upload" to burn the firmware to your arduino and use the FluxSDK to communicate with the new tool head!

• Hardware configuration:

Connect the Flux delta's extension port "TX" & "RX" to the arduino pro mini "RX1" & "TX1",also the power supply(3.3v and ground) for arduino board.

You can plug a led or any ttl component to arduino digital pin 2 and groud , then it would be driven.

• Using the FluxSDK , see the FluxSDK document.

Funtions

• codeSeen() : use it to find command
• codeValueShort() : get value after found command
• getChecksum() : before send back response ,you should attach the checksum

if (codeSeen("HELLO")) {

    sprintf(sendBack, "1 OK HELLO TYPE:USER/MYTOOLHEAD ID:0000 VENDOR:BANANA VERSION : 0.0.1 ");

    sprintf(sendBack, "%s*%d", sendBack, getChecksum(sendBack));

    serialPort.println(sendBack);

}

• commandHandler() : handle your command here

Protocol

• HELLO

1 HELLO *[CHECKSUM]

1 OK HELLO TYPE:USER/MYTOOLHEAD ID:0000 VENDOR:BANANA VERSION : 0.0.1 *[CHECKSUM]

• PING

1 PING *[CHECKSUM]

1 OK PONG ER:0 *[CHECKSUM]

• YOUR_COMMAND

1 [COMMNAD] *[CHECKSUM]

1 OK *[CHECKSUM]

• MULTI_PARAMETER

1 [COMMNAD] [PARAMETER] [COMMNAD] [PARAMETER] *[CHECKSUM]

1 OK [RETURN_VALUE] *[CHECKSUM]
