Thanks Ttelmah, for the very good answer...

Well, to be honest I always thought that was very possible to make asymmetric cryptography (including generate the keys) in the PIC's hardware, but I am ...

Hi everybody,

I know this is a regular question (if there is any library that implement), but this time I'm asking if it is possible to do asymmetric cryptography in a PIC family device (dsPIC, PIC ...

To add an update, the RFC 1321 test code is consuming 13% ROM and 25% RAM of PIC18F2620, but it works correctly, different from PCD with PIC24.

If I understand correctly, you already have the imple ...

my thanks go to all active users of the forum Very Happy

, but we have to say thanks very very much for the names already mentioned (Ttelmah, PCM, Ckielstra and others)

hummm... i'm not understanding what are you trying to say...

you can't send and take data? Are you asking for example code using these functions?

if can somebody write little code for example ...

Hi everybody,

Well, I'm developing a circuit that uses 2 rs232 and a ds1307, and all of a suddenly the program started to behave strangely. I could localize (I guess) the source of my problem, and ...

hi everybody...

I want know if there is a way to declare the priority of an interrupt in the PIC 18F's.

As far as i know the directive #priority only tells the order that the interrupts will be ...

thanks to everybody for the explanations... i will read the links and do some tests...

but the topic already explains a lot

hi everybody,

Sorry to run out a litle bit of the main theme discussion (CCS C) in this forum, but since every pic has a crystal associated and think this could be apropriate

Anyway, the questio ...

thanks Phil,

i had check the datasheet, it was just a type error, but thanks again

why the squarewave output pin is disabled in the init() and set_date_time()?

if i want a squarewave of 1Hz i'm only have to replace the

i2c_write(0x80);

to

i2c_write(0x01); ...

i was doing some research, and found the ds1307 hardware. this already implements a RTC.

ok, but i think this not fit for me... because i want to send a configuration to the pic and depending on th ...

ok, i bought 2 diodes and put them in series with the power source and the program stop to behave strangely.

But now I'm printing the time, and after 12 hours the program delay a couple of seconds ...

my compiler version is 4.057 and this simple program works fine.

i will try add a diode in series, really haven't think about that.

thanks

Hi everybody.

I'm using the code posted by ckielstra to implement a Real Time Clock, and every minute i set a flag that make a led to blink. the problem is that after a couple of hours the led just ...
