but for everything now i'm here.
by the way i have to implement this project in this months.
Thax

Hello Everybody!
I want to generate a 50hz signal using timer0, and I want to vary the duty cycle of the signal from 1ms to 2ms(servo control). I didn't test it, so I want to take in consideration al ...

Thanks for everything guys. Really the problem was the lcd. But i want to say something i worked a lot using proteus and i can say that it resolves 60% of the work (so i don't trust it at all) .... in ...

Thank you for everything .. Smile

Now finally the data is received correctly but the problem was something that i didn't expect. I canceled the lcd_init() and all the "printf" so the only comm ...

No I'm doing the test in hardware and all of the steps that I'm going talk about are in hardware:
Here is the code for the both since the code send and receive data:

#include <16F877a.h>
#F ...

Nothing!!! I don't know what's wrong, like I said each pic can receive data from itself (so the code and the hardware are right) but can't communicate each other!!! (I'm going try all the baudrate).

yeah i know that...so I grounded the two board and the voltage of the pic is the same ..so the first pic is 5.01 as the second... and now i realized that it always receive data.. so it likes the if(kb ...

The distance that I want is short (few cm)... now:
I make 2 circuits pic hardware and for each one I tried if it works or not. So I sent an integer and receive it (connecting the tx to rx directly of ...

hoangkhuong: I make few months ago... connection between pic and pc and was successful. I'm gonna retest it on it why not!!!
temtronic: Should I have to use max232 between two pic for serial communi ...

temtronic: The lcd works. I tried it alone and it's perfect, and yeah I added errors without results!!

ckielstra: After I select the program where is the code button!!

I make code without the rs ...

Hello everyone !
i'm working on send integer between two pic16f877a, i know that is a simple topic and the codes are easy, but still don't work so i decided to ask you maybe there is something missin ...

I write the code for the gyro idg500 and obtain good results but there
is still the problem of its drift. Now I'm gonna combine with my
accelerometer adxl335 but it seems that I am gonna use anothe ...

thx ckielstra for the advices!
Yeah, you are right for the #byte port_a = 5 ...etc
But for adc_channel I have to use more than one.
But for the sequence of the timer command you let me notice righ ...

the code compiles but doesn't work!!!
so it's better put the maths inside the while loop and not inside the isr!!
but u said that timer0 count to 63535 but the timer0 is an 8 bit,so overflows when t ...

In two words what I've done is a code without precision in time which needs a gyro that sends datain high freq. Ok I don't know how the ccp trigger event works (I'll read about it now), but the compil ...
