Perfect, it works.
Just a little more thing.
For me the easiest way to write the 24bit word is in binary (because with the registers table I can easily set the proper bit):
dac=spi_xfer(id,0b00 ...

Hi there.

I'm having hard times to menage the DAC7562 DAC via SPI.
I use a PIC18F67K22@48MHz and the SPI bus is working (oscilloscope tested).
I use the SPI PIC hardware pins: 34=clk, 35=data in ...

If you are only looking at one channel, you can set the adc channel outside the loop which eliminates that and the following delay from the inner loop.

Ok, corrected.
Thanks.

i sure hope the VAR 'current' is an int32

current += read_adc();

No, it's an float.
Why?

OK, thank you very much guys.
Problem solved by means of Alan's formula and a few of small adjustments because of the components tolerances.
ASMboy, cant change the design, I already have the PCB wi ...

Hi all.

I'm using an ACS713 as current sensor with a 18F67k22 @ 12bit res.
I don't have any clue about how to calculate the scaling factor to get the right Ampere reading.
As per specs. this sens ...

OK guys, now it's working.

Thank you!

Hello,

I have a problem here with a undefined identifier in my main.c
here's part of the code:

the strange thing is that is only the first elemen ...

The best would be find a very good book with also advanced features of the PIC like timers, PWM, interrupts explained in depth.
I already know the basics of C but now the problem is the integration o ...

Hello.

Don't know if I'm off topic in this forum but hopefully this thread will also help others.
I'm looking for a good book explaining the basics of the MCUs and programming with the CCS compile ...

Hi,

I have a PIC18F452 with 20MHz crystal behaving strange.
When I insert the lines :

output_low(PIN_D7);
delay_ms(1500);
output_high(PIN_D7);
delay_ms(100 ...

Hi.

Somebody knows which is the difference between PIC suffix I/P and
I/PTSRL?

The datasheet of the 18F87K22 says that TSRL is silicon revision A3.
Now, since Digikey has both of them, is the ...

...Add NOPLLEN to the fuses (just worth trying), and literally do a one second on, one second off LED flash, using no other hardware, program this into the chip and see if this works. If it does then ...

Have you tried using a 16mhz oscillator in ec2 mode with the 4x PLL ??

It'll be difficult as the oscillator is a small SMD package and I don't have the 16MHz one.
Crazy.

I did some further investigations.
I have a LED on the board.
with the #use delay(clock=64000000)
the on/off timing of the led is half the time I set in the software.

If I set #use delay ...
