USB Infrared Toy / Re: pic18f2553 tv-b-gone with european code
little update: i made all 138 code works and fit in the pic, i change the linker file and use 2 of the usb databanks so i don't think that the usb module is still working but i don't need it.
the files are in the attached.
P.S.:if you have a scope (and free time) read the previous post.

USB Infrared Toy / Re: pic18f2553 tv-b-gone with european code
i controlled all the function with the mplab sim and now it works, it turns off the european television.
I attached the code.Thanks ian for the suggestion.
Now i'm working on a smaller and powerful version.
i need to control 4 ir led ( http://it.rs-online.com/web/p/products/6997626/)and i was thinking of using one transistor per led and one main for control the other 4 transistor, is a good way to do it?Any help or suggestion is very appreciated.

General discussion / sd card datalogger
i wanna make a datalogger that records gps coordinate and velocity and accelerometer value on the three axis with a pic and save all the data on a sd card for later pc analyzing.
Does anyone can point me some pic code or theory for make the sd card works?
for my application is best to have all the datas save on a .txt file.

Project logs / upov - pov keychain
i'm making a micropov with 8 leds, 3v power supply and tilt swicth for sensing the direction.
i made a prototype version of it on protoboard and the it works very well, the image is very stable and can see with naked eye.
The final board will be all in smd and will have a button for the reset so after the effect or the pov it goes to sleep because i don't want a on/off switch.
All the documentation is in the attached.

P.S.:i'm not a good coder and the function pov is very strange and complicated but it works and that is the important thing.the delay value "spaziolettere" is hand tuned and 1ms is the one that works on me.
if you want to see a video of it PM me and i will send it via email

USB Infrared Toy / pic18f2553 tv-b-gone with european code
i change the code of the irtoy for work with a 18f2553 at 8MHZ.The problem is that it not turn off tvs.
i use the c18 library for the pwm and also for the delay.
the ir led is working because i can see it blinking trough a camera.
i change also the freq to timer function.
thank you for the help.

THE CORRECT FILES ARE IN THE SECOND PAGE.
