Help..How to use LM95071 with pic micro

[Shohadawy]

I want somebody to give me an advice about using the LM95071 as a temperature sensor in a temperature control circuit that is pic-based

Is this your final year project?

When is it due in?

Have you searched Google

This reads 16 bits on an SPI device.
The initialisation needs to set tncs and tsc as outputs, and tsio as an input.
This routine is called each time you want to read the temperature.

readtemp

	bcf	tncs_port, tncs	;starts on high to low edge
	movlw	0x10
	movwf	count1		

read_bit

	rlf 	temp_lsb, f
 	rlf 	temp_msb, f		;rotates both bytes left
							
	bsf 	tsc_port, tsc		;raise clock

	bcf 	temp_lsb, 0		;clear bit 0
	btfsc	tsio_port, tsio		;check data from LM95071
	bsf 	temp_lsb, 0		;set bit 0 if data is set

	bcf 	tsc_port, tsc		;lower clock


	decfsz	count1, f		;decrement counter
	goto	read_bit		


	bsf 	tncs_port, tncs		;raise Not Chip Select = stop LM95071

	return

What do you mean by SPI device???

I think you can do some research for yourself more easily than asking us.

OK ,I'm sorry that I've disturbed you... but it's up to you if you don't want to answer my disturbing questions

He's already answered, your question, read the link in Wikipedia and don't use such an obscenely large font.

We prefer a larger font, sometimes color works. We're unlikely to do your homework for you, but many work for cash
