I am of Brazil. I have this project that it needs a crystal of 400MHz (as this in the figure above). The constructor of the circuit informed me to use the LMX1600 together with a MCU to obtain this sp ...

Ok, how pin go my circuit, and anybody help-me in code to PIC load of 400Mhz ?

It�s problem, because the project run cristal of 400MHz and 200Mhz.
other MCU type TEXAS run 400MHz in PLL.
The men of this project talk-me of use LMX1600 (National) and MCU to generate 400MHz.

Hy people
I need of cristal 400MHz, and talk-me to contruct with PLL, but i do no make, i need help.
Thanks.

Hy people.
I need know model of transformer to conect in ENC28J60.

Thanks.

Debtor, I go to try another solution.

I agree, i question for do, it�s possible, PIC with LINUX.
I job in project, creat one switch with 8 ports RJ-45 to controler status of interface remotely, i find a RTL8309SB to job, but i do not kn ...

Hy people.
I need of file PORTB.H, but my compiler (version 3.249) not found this file.
plese send-me it�s file, or post in forum.
Thanks.

Hy people.
It�s possible install LINUX or FREE-BSD to load in MCU PIC ?
If possible, how version and model MCU minimun ?

Thanks.

My friend, try it�s:

mod_lcd.c
#ifndef lcd_enable
#define lcd_enable pin_e1 // pino enable do LCD
#define lcd_rs pin_e0 // pino rs do LCD
//#define lcd_rw pin_e2 // pino rw do LCD
...

This code, it's correct:

#include
#use delay (clock=4000000)
#fuses INTRC

main()

{
output_high(PIN_A2);
delay_ms(1000);
output_low(PIN_A2);
delay_ms(1000);
}

Try make protocol 1-wire to comunication, the 1-wire protocol permit 1 master and any slave with 1 pin from PIC, and the protocol it�s simple.

The code it's ok, but, have insert:
#define DS1820_SKIP_ROM 0xCC
#define DS1820_READ_SCRATCHPAD 0xBE
#define DS1820_CONVERT_T 0x44
I go job to add precis ...

Hy, the code stop begin call function, read temp_indoor, but, my code continue load, because call interrupt from serail RX, response, and i add call from SKIP ROM.
Thanks.

Hy, i need check two temps, indoor and outdoor, i use DS1820, from Dallas, the protocol is 1-wire, whats read two sensor ?
My MCU is 18F452.
Thanks.
