Why we have to set the adcon1 in this 7-segment display using PIC 16F877?

adcon1

**broken link removed**


Code: 
MOVLW  0X06  
  MOVWF  ADCON1

This example is to make a "1' on the 7 segment

how come we have to set the adcon1 ?


Thanks
 

Re: adcon1

Hi,

When your PIC powers up, the default ADCON1 sets all the analogue ports ON.
So as you are wanting to use the ports as Digital you must appropriately set them by means of loading 0x06 to ADCON1.
See the datasheet for further details of how to use ADCON1.

Notice that its only setting them to Digital, you still have to set the TRIS register for the input or output direction you require.
