But, Why is it important to tell the slave device " that you're done retrieving data from it"...?
In the CCS manual i2c_read(0) indicates do not ack. I ...

Hi
I would like to communicate a PIC with a chip using a I2C communication. I checked the CCS commands. It seems it is easy. But I don't find the way to check the ACK answer from the slave. Maybe usi ...

At the end I took one of the ideas of Ttelmah. I made a connection to a TTL pin and it works... I dont need to implement more hardware Smile

Hi
I am using a PIC 18f2620 working with a voltage of 5V.
I conected to the pic a bluetooth chip ( 3.3 V) using a usart connection .

To send commands from the PIC (master device) I put 2 resist ...

hi Ttelmah
Thanks for your help.
I have not finish all I wanted to check but it seems the origine of the problem is the delay_ms command in the int_ext.
I have not checked your program but I have d ...

yes I have...

delay_ms(500); // debounce button

I didn't put it before because the button works correctly. The problem is the enable and desable int_timer0 process. It works the fir ...

Hi Telmah. The code of the #int_ext is:

#INT_EXT
void ext_isr(void){

......

if (expre1){
disable_interrupts(INT_TIMER0);

}

if ( expre2){
disable_interrupts(INT_TI ...

Hi
I would like to use a #int_ext and a #int_timer0.
When I push a button the #int_ext works and inside that interruption I would like to enable or disable the #int_timer0 depending of some conditio ...

Hi
I am programing some code in a interruption int_EXT. I use a PIC 18F1620.
The program works fine but when I try to add new code using if (expr) conditions the PIC doesn't recognize them.
For ex ...

Hi
I tested
.......
setup_adc_ports(AN0|VSS_VDD);
setup_adc(ADC_CLOCK_DIV_16);
...........

And now it is working correctly. I don't know exactly what is VSS_VDD, the reference is 5V maybe?
