16  Using Arduino / Project Guidance / Re: Machine Vision LED Controller -- advice requested on: January 28, 2012, 12:57:08 pm
Any suggestions on a better protocol to implement, or should it be something done by scratch?

A software GUI would be needed for users to adjust channel power and apply their settings to the controller -- run from a host PC installed somewhere nearby.

A serial command interface would contain a list of commands and may look  something like this:

Command: Set channel power

C = channel number
### = 0-255


This is geared towards an industrial environment with automation as a focus, where there is potentially numerous machines which are run all together through software. It is common to have software send out serial commands (rather than have a user interface). It is a vision application, so the lighting works in conjunction with camera imaging systems, sensors, etc..

 Typically used in automated inspection (inspecting beer bottles for cracks/imperfections is one example). Beer bottles may be travelling on conveyor where a camera images the bottle with a light flash or continuous lighting. Software algorithms compare defects and reject/accept the bottles as they move along.

This is just one example, but another example may be a system that must adjust intensity levels, or color settings, on the fly due to a changing product that must be inspected. This would all be automated, so a well implemented serial protocol is necessary.

Still cannot find any support for this..

I'm working on a program where I can control up to 4 channels of lighting. Lighting current source is independent of the arduino and is already developed hardware. The controller will have the following control methods:

1. TCP/IP server -- user interface for use over a browser
2. USB GUI -- user interface for serial users (also low-level setup for the controller)
3. Serial command interface -- users can control the unit over serial commands rather than software

Control functions include:

1. Channel settings for 3-4 channels
2. Memory to save settings
3. possibility for pre-set configurations (call up stored channel settings with a command)
4. user adjustable network settings dialogs, etc..

My progress so far:

I've played with the Arduino Ethernet, and have built a rough but functional 4-channel control (actually only 3 channels at the moment). No frills there at the moment. Thinking ahead into how I can incorporate all these control features, I need to plan something solid from the beginning so I don't waste a lot of time developing one piece, only to find out it really won't be compatable with a different piece (IE TCP/IP vs. Serial).

I've been looking at Firmata for the serial side -- is it feasable to implement Firmata, as well as custom TCP/IP firmware in the same build? Is there any functionality in Firmata for TCP/IP?

Someone give me a sanity check -- am I even on the right track?

For any Arduino "professionals" out there -- this job has potential to pay for contract work, if anyone shows interest.

Any advice you may have would be greatly appreciated!!

same problem here. Tried both arduino 0022 and 1.0, with all the firmata versions for each.. no PWM functionality.

Anyone got this to work properly?? smiley-cry

Thank You, your code works well.

Shortly after I posted this, I figured out a couple things -- one thing being the difference between "print" & "println" ( I warned you that I was a newbie); so I got closer on my own..

Then I went further to add the periods, but took a different turn using a FOR loop (which added too many periods, etc..).

I may post more questions as I move along with my program -- thanks again..

Total newbie here, just a fair warning..

I'm looking to store an IP address into EEPROM. The IP is then read back from the EEPROM in serial.print fashion.
Would I format this code to make it display the IP address on a single line, seperated by  ".", like this:

IP Address

Ultimately this is a bigger project planned with the following goals:

1. Have user input to change/enter IP, Gateway, etc..
2. network information gets stored into EEPROM
3. will work from a server-based ethernet interface

The current I have shows the output like this:
IP Address

Any helpful tips would be appreciated!

#include <EEPROM.h>
#include "EXROM.h"

void setup()
  byte IP[] = {192,168,24,1};
  byte IPsize[sizeof(IP)];
EXROM.write(0, IP, sizeof(IP));         //write the IP to memory, IPsize, sizeof(IPsize));  //read the IP from memory
 Serial.println("IP ADDRESS");
     for(int i=0;i<sizeof(IP);i++)
    Serial.println(IP[i], DEC);
