yes, but if I don't change the value of the input, the output doesn't change.
my problem is that PIC see 0 but I put 1 on the pin; the circuit is a simple pull-up (R=100K) and a switch between R + PIN and GND.

I just find the solution; I forgot tu set a register...
Hi,
I have e stupid problem, but I can't find the solution,
this is the program:
#include <p18f2520.h>
#pragma config OSC = HS
#pragma config WDT = OFF
#pragma config LVP = OFF
#pragma config PBADEN = OFF
void main (void){
// Imposto PORTA tutti ingressi
LATA = 0x00;
TRISA = 0b11111111...
Hi,
thanks for your reply.
I'm using C18;
I just have a library guide, but I didn't find the istruction set,
I know that there is one register for address and one for data, ...... but where???
Hi,
Do you know if I can write in Data Memory of a PIC18F44J10???
I saw the datasheet that there are 768(Byte) but I do not find the register where I have to put the address and the data...
anyone can help me????
Re: Trouble with PIC18F2520 Master Vs. ISD4002 Slave using S
I got it!!!
Code was good, the mistake is in the bit sequence, it must be reverced:
from bit 0 to bit 15(Most Significative Bit);
and now it work.
At last but not least, watch out for the timing, the frequency must be under 1KHz...
Re: Trouble with PIC18F2520 Master Vs. ISD4002 Slave using S
Hi,
pull-up resistor on the MOSI line is not mentionated in the datasheets
The SCK signal must be under 1KHz, impossible to reaize with the internal timer of PIC, so I bilt this fool code to generate the transimission:
#include...
Re: Trouble with PIC18F2520 Master Vs. ISD4002 Slave using S
Hi,
thanks for your suggestion, I will look for it.
For the Power, I'm using a 3,3V.
In the datasheet of PIC18F2520 (fig.26.2) for my frequency operation 3,3V it's ok.
For the connection mode, I followed the schematich in the...
Re: Trouble with PIC18F2520 Master Vs. ISD4002 Slave using S
May be the problem is the timing of the comunication
the ISD datasheet tell 1KHz max frequency.
the SPI module can use the Timer2 that can be set with a prescaler of 1/16 and a post scaler of 1/16.
I'm using a crystal of 4MHz...
Hi,
I'm traying to drive an ISD4002 with a PIC18F2520 using the SPI.
I do any kind of test, the SPI work correctly if I use another PIC instad of the ISD,
data transfer was good; but when I use the ISD I really don't know how to test it....
This is my program, I think it's correct but...
Hi, this is my first time in a forum, sorry for my intrusion but I have a problem with the same device, ISD4002.
In my case the ISD do not recive any command.....
When I sand a PLAY command, it would sand me an interrupt but it do not appen....
why?
I did a lot of test but anyone work.
I'm...
