DOUBTS : pic12f675 adc program | Piclist

A discussion group for the PICMicro microcontroller. Also called the Microchip PIC, this list is dedicated to the use and abuse of this fine, simple, microcontroller. Close to topic posts are welcome, ie. general electronics.

hello, THE ISR WAS ALREADY PRESENT IN THE TEMPLATE OF PIC12F675...hence i did not delete it without labelling main it completes the whole program expect for adc loop....i don't how? i tried 'step into' so it executes 3/4th of the program. in the file register window i get all values as zeros but yes when i go to view> watch i see values for all the registers .....but in the o/p registers where i need to see values i.e adresh and adresl it is always zero . even i felt it goes to infinite loop mainly because i set go/done bit again in the loop but i did not the understand jump to -1 as somebody suggested can u please explain in detail how i can go about doing it .thanks for ur suggestions once again its of great help since this is my first project. I DID NOT UNDERSTAND **HOW WE CAN FEED AN ANALOG VALUE TO THE PIC THROUGH THIS SOFTWARE PGM .....IS THERE ANY FACILITY TO GIVE INPUT VALUES..BUT WITH THE H/W IT TAKES THE BATTERY CONDITIONS AS VALUES SAMPLES IT N CONVERTS.....BUT HOW DO I DO IT IN THE PROGRAM.. ** HOW DO WE CALCULATE THE RESOLUTION FOR ADC.. SO AS TO CHECK THE VALUES. ** IN THE ANSEL REGISTER BITS3-0 R FOR ANALOG SELECT BITS 0= DIGITAL I/O ;PIN ASSIGNED TO PORT OR SPECIAL FUNCTION 1= ANALOG INPUT HOW CAN ADC HAVE A DIGITAL INPUT B'COS THE I/P HAS TO B ANALOG ** IN THE PWM MODULE WHAT VALUE SHOULD I MOVE TO T1CON .....I AM USING 1:1 PRESCALER AND INTERNAL CLOCK

I suggest you go to the microchip web site and find their numerous appnotes for for ADC. You really should spend some time reading them as all the answers to your questions are there. Good luck with your assignment.
