Post by thread:16F873 A/D & PWM code wanted

<x-flowed>Hi all I would like to read a varying input voltage from a 10K pot(+5Vdd to GND), display it on 2 - 7 segment displays, and vary the PWM output from 0 to 50%(or greater) duty cycle. The display need only show the voltage from the pot in unit and decimal form. Example: 1.0V, 1.2V, 1.5V, 2.0V, 2.5V, etc.. The PWM output should track the displayed voltage. So far I have a rudimentary code that reads the pot and displays the level on portc in binary. I have added a lookup table to run one 7-segment display. I don't know how to use the PWM yet. Any help will be greatly appreciated. Thanks in advance, Mark Willcox ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com </x-flowed>

There is a file on the microchip website entitled "Care and feeding of the PIC16c74 and its peripherals". In it is code doing all of the above except the display ( but it does send it via the SCI) This page demonstrates A/D, PWM and comms as you have requested. {Original Message removed}

I've been unable to locate the referenced file "Care and feeding of the PIC16c74 and its peripherals" on the MicroChip website. Would you please post the URL of the specific page it can be found on? Thank you. {Original Message removed}
