HI ..
i make a project about " bubble detector " device and i need microcontroller program to compare between 2 volts " replacing comparetor "
* when the port A have one , port B should make buzzer to alarm *

i need the code in assembly , using pic16f84a

please anyone answer me

Thank you , i appretiate your help

 

No one, not even yourself, can code this project without knowing everything about the external hardware.

By the way, if you can determine how to direct a branch based on a numeric value, you will have most of the programming done.

 

Pic 16F84A has only digital input/output. It has not adc on board. So if you need to measure analog you have to change type of micro 16F690 has 10 bits adc input ports.

What kind of output your bubbles sensors have?
