I was over at www.ljcv.net and i noticed that they have the source code for there ethernet webserver boards on the site.
having remembered what ian has said about the current stack is "free" but not available for distribution i was curious and checked the license that is included in the code that they have.
it looks like the older v3.75 stack is able to be distributed.
im not sure how usefull this is but i figured its at least something to look into further as it might make development easier.
after a bit of searching i found a power supply. gives 7.8v when plugged into the twatch. I thought it might be a little high bit it seems to cope with it ok. I did a few temp measurements. the regultors started to get warm. the 1117 seemed to top out at 50 deg c. with the 7805 sitting at 33 deg c so not to bad. what worried my more is the fact that the pic seems to run pretty hot. it was also at 50 deg c. Im not sure if that is normal but it seemed hot to me. i confirmed that the 1117 was outputting 3.3v so its not overvolted.
As with the others i found that the backlight really needs to be on for it to be usable. is there a precompiled firmware that has the backlight on?
i keep thinking about an upgrade to the stabndard text based lcd.
Does anyone have suggestions for a GLCD preferable color that could be used in "projects" like the ones here.
touch screen would be nice but not a requirement.
i guess the ones that come to mine for me are ones from soem other easily available device eg: iphone, sony psp, nintendo ds etc. but i dont know how they would go .
Looks like my twatch has shipped. I got my confirmation email tonight what i got home.
Here's hoping that they added the acrilic frame to the order like i requested.
So hopefully only a couple more days till some hacking fun, Lets hope we can find someone to write a dll for the serial mode for LCD smartie, now that would really be great.
i have been thinking about an upgrade to the original pic webserver. but since you released this it seems to fit better here.
I was thinking of somthing like the following. remember this originally came from the webserver idea.
Upgrade the Micro to a pic32 micro with usb. this give more i/o, more memory more speed for not alot more cost over the pic18 or pic24 series that are currently used.
add the usb port add micro sd slot add the option of running either a stanard 20x4 text display and or a color graphical display (the psp or maybe the nintendo DS displays come to mind.) a display with a touch screen would be nice or the option for 5-6 buttons.
for me the ideal situation was to look into how to create a display that is compatible with the external slideshow displays. hopefully the extra horsepower of the pic32 would be enough to run the display as decent frame rates. see see http://en.wikipedia.org/wiki/Windows_SideShow for slideshow info also with either touch screen or buttons would allow it to run in different modes.
having the displays as an option to the board allows us to run a webserver board or add the displays for a usb or standalone display either color or text based.
i was thinking if it could be made under $100 with a decent color display it would be ok. With the text based display i dont think it would be much more than a twatch as there isnt much more in the parts.
anyway this was my idea that ive been mulling over for a while. im not sure if it fits better here inthe twatch area or int he webserver area.
Since im using hyper terminal. when i type the ? command the data scrolls off the screen and when i scroll back up htper term seems to have a bug that corrupts the data that has scrolled off the screen.
so i was missing out on some of the help menu commands.
so i started thinking about redesigning the text to fit onto a single 24x80 screen.
but in doing so it seemed to make more sense to split the ? command into 3 sections. or even 3 commands. As there seems to be 3 sections. Menu, Syntax, Raw bus operations.
Can i suggest a software mod to pause after each section of text and wait for a key press.
Also maybe allow ?m or ?s or ?r to show only the 3 different sections. This would also open up the option of doing extra help screens (space permitting) for things like ?1 for 1 wire help, etc.
just a quick not that this board seems to be a slightly different layout and doesnt require the jumpers mentioned in the post. except for maybe the resistor jumpers if you run fets.
Also i couldnt find R8 on the parts list. i had to check the schematic. its the same as r7 , 10k ohm according to the schematic.
anyway i hope that helps someone.
i still have a few bits to add being i was short in my parts box. but a couple if regulators and some fets and i should be done.
i decided to download the source and see if i could add my 1-wire chip id's myself.
i have downloaded the v2 source file and loaded into MPLAB fine. edited the file as i think it needs. When i hit the make button i got a "Couldn't locate build tool. Check tool locations." message.
i checked the MPLAB install options and i have everything ticked.
I was wondering whatr compiler you are using ? hope fully once i have that i can work out where to point the project to the compiler.
I was wondering if anyone has any updated software for this.
I would love to be able to do more with this. from memory there were two subroutines that allowed clicking on the webpage to run routines. it would be great if they were working for someone. i was lookign at it at one stage but i didnt get to far.
