I want to do a temperature sensor project. I using LM35DZ which is analog reading. so to convert the analog to digital i was found that the ADC0804 is suitable for this case... so how i want to read ADC0804 output from PIC16F84A?? Maybe has some website will introduce to me?

TQ

It's not something I've ever done, but it's usually a simple syncronous serial protocol and quite straight forward - the ADC0804 datasheet should give details. But if you do a web search you may well find existing code.

However, it seems a pretty pointless exercise in the 21st century, why not choose a current PIC rather than an obselete one?. The 16F819 is essentially a 16F628 with a ten bit A2D - do the job for less money and with fewer parts?.

I was has both PIC, so how i want to implement the conversion from analog to digital? can you give some code example :lol: . Example: if my temperature is reading 10oCelcius (b'00000001') how i want to get the reading from PIC? All the pin I/O (such as: PortB (8 I/O)) must to be use? :roll:

or

On your tutorial has all this thing? if has, which tutoarial that you was done?

TQ ops:

My analogue tutorial shows how to use the A2D converter, it's based on the 16F876/7, but the code requires almost no changes for the 16F819.
