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 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.
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.
