Project Help- Simple ADC

Hi guys,

I am a newbie on microcontroller. Currently I am doing a project with c18 p18f452 . Basically I have a sensor and I need to display the voltage level from the sensor on LCD. Can anyone familiar with this ? Please help me on this. Thanks.

For that you required Micro controller with inbuilt ADC.
Just interface Microcontroller with LCD & send data microcontroller to LCD.

I guess this will be helpful.

Let me know if you need more info.

I using pic18f452. The ADC result is in ADRESH which is binary form. How do I convert it to decimal form and pass it to LCD?

hi! first u use an micro with onchip adc then confogure its adc with internal or external reference voltage internal is mor convinient uthis can be done by setting few internal register then by measuring the adc voltage you will get a digital value that will be stored in a dedicated register then read this get many value as your require and then take an average of them values and compare or convert the value to show on LCD. if u need more help ask me.
