Hi,
First of all.... congratulations for the lib!!

I´ve tested it, and it has worked fine. I have a doubt... is there a generic function to show a bitmap?
I´ve modified the bitmap.h using Image2Code and it has worked but it would be great have a generic function to add all you want.
( I´ve used TVout_R5.91 )

Thank you

Hi,
I've used a NewHaven Display => www.newhavendisplay.com/
It's very big and cool!!!!  ;D  I don't remember, but something less 70 dollars.
I've choosen one based on T6963 controller. I bought directly from this web.

It's very cool!!

Regards,


 

Cool franksmicro!!

I´ve been tinkering with CAN bus for a while.....

http://real2electronics.blogspot.com/2010/06/can-bus-mcp2515.html

I´m sorry,it´s in spanish. It´s not a proper library, it´s an explanation how to use MCP2515 and the basic functions needed.
I´ve some links to code and hardware.... I´ve just added a link to your library!

DaveAK, if you also have a library, please let me know the link and I could add. There are no many projects with CAN bus and Arduino.


I did this...

Hi,

You can read about it in Sparkfun tutorial (Sensor Interfacing):

You have to install ipkg-opt and redirect some folders with mount --bind :
mount --bind /mmc/jffs /jffs
mount -o bind /jffs/opt /opt

Now /jffs and /opt point to MMC folders.

I´ve installed:

• setserial
• php-httpd (port 8080)
• curl

I continue with routers`s configuration web server in port 80.

You can look the optware packages (1241 ):
http://www.dd-wrt.com/wiki/index.php/Quick_list_of_Optware_packages


It´s an easy and perfect solution!!!
Although I have to learn how-to with openwrt...step-by-step   ;D

Thank-u!

I´ll keep you updated



Best Regards

I´ve found Harsel as optware package.

Haserl is a small program that uses shell or Lua script to create dynamic content with CGI scripts. It is intended for environments where PHP or ruby are too big. On nslu2, because of the limited RAM resource, CGI can sometimes outperform other solutions. The webif project for openwrt firmware uses haserl to build web interfaces for routers.

Nemik,Is it what you recommend me?

Hi again,

I´ve just received the SD Sniffer board from Sparkfun and I´ve working the SD hack for the router.




I´ve achieve work with DD-WRT and an old 1 Gb SD card.
There is a Tomato firmware which has a driver for moderm SDHC (I´ve tested 4 Gb), but I don´t know yet if I can use Optware with this firmware.
http://gemini.net.pl/~slodki/tomato-sdhc.html

May I install with opkg a package for using sd/mmc HC with Kamikaze?
Because the problem of DD-WRT is that only work old SD...

Now:

root@ARDUINO:/jffs/opt/bin# df -h
Filesystem                        Size      Used   Available Use% Mounted on
/dev/root                          2.8M      2.8M         0 100% /
/dev/mmc/disc0/part1    960.7M      5.9M    906.0M   1% /mmc
/dev/mmc/disc0/part1    960.7M      5.9M    906.0M   1% /jffs
/dev/mmc/disc0/part1    960.7M      5.9M    906.0M   1% /opt





Thank-u!!

Best Regards,



Igor

I think you have 8Mb of flash and my router only 4Mb (WRT54GL).

root@OpenWrt:/jffs/usr/bin# df -h

I´ve to read and search in internet all the info you post here...
I´ll keep you updated.

Hi nemik,

Thanks for encouraging me....I´m tinkering with it.

My first step has been install Gargoyle package (kamikaze 8.09.1 + graphical enviorment). It´s working good and it was easy with the *.bin archive (as dd-wrt).
What do you think about it? It´s very easy to use....http://www.gargoyle-router.com

I´m not idea about linux...Maybe some of my doubt are very basic, but I´m a rookie....

I´ve achieve install curl.... ooooeee!!!!. I´m not sure how, but now it´s working  ;D.
I had a problem, because when I tried opkg install curl, the answer was :
Only have 760 available blocks on filesystem /, pkg libopenssl needs 1270

I´ve search about it, and I´ve added to /etc/opkg.conf:
option force_space
Bad idea???   :o


How I know my free space to install packages?


After the change, I´ve tested again and.....
Now:
curl -u real2electronic:mypassword  -d status="Thank-u nemik! Sended from:LINKDUINO" http://twitter.com/statuses/update.xml
And.... it works!!!! he,he,he (You can see => http://twitter.com/real2electronic)

Hi,

I´d like to have a firmware with:

1) Advanced bash commands (wget with post, curl, ....).  Because with it I could use Pachube, change twitter status, mail,...
2) Web interface to configure it (like Tomato,Gargoyle,Luci,...)
3) I should be able to use the serial port
4) Web server compatible with cgi scripts
5) Send the firmware as dd-wrt, with a *.bin file or similar

Because using bash scripts is something "universal" and with documentation. It should be "easy to do".
Is it possible?

Thank-u for the information.

Kind Regards,



Igor R.

[Igor R.]

Yes, please!!

There are a lot of people working with linux based routers, but not info...

People, as me, who are not familiar with linux, is not easy to start with it. And all information around openwrt,x-wrt, luci,... are quite confused.


Kind Regards,


Igor R.

Cool!!  

It would be fantastic if you explain a how-to tutorial!! Maybe it´s a specific application, but it helps to other people....(always it's good learn how other people have resolved their projects).

[Igor R.]

Hi nemik,

Thank-u!! I´m doing the same as you (not directly because is 3v3). At the moment, I´m triying only with DD-WRT, in stead of OpenWRT, because it has an easy configuration web page.
I also try to do the router programmation using bash scripting.

The idea is to have a "generic hardware" for the prototype phase of an electronic project (always trying the easy way to resolve things).


What have you done with arduino+Fon?




Kind Regards,

Hi,

Another example, this time how to control a LCD from internet/lan:

Hello,

We´re working in a project Linkduino: "Electronic Rapid Prototype Hardware".
http://cid-d2ee689f353f15bc.skydrive.live.com/self.aspx/P%C3%BAblico/Linkduino%20brochure.pdf

The main idea is to have an ECU to be able to be very quick in a prototype phase of a project.
At the moment we´re working joining a linksys router (or similar) + Arduino Mega + specific hardware to have rs485,can bus,...

We try work as easy as possible (DD-WRT, shell script,...). For sure, there are better methods (openwrt, cross-compiler,...), but it requires high skills.
