1-wire not working on other port than B0
PostPosted: Tue May 04, 2004 2:59 am     Reply with quote
Question I read dallas 1-wire devices on a PIC16F877 with the CCS touchl.c example program. Everything's OK, but if I configure it to read on any other port than BO e.g. B7, I cannot read the device? Any suggestions on what to try?

Thanx

Hi Levett,

You need to modify both the TOUCH_PIN & TOUCH_PIN_BIT in the touch.c driver file. For an 18F452 using pin B7 the following would be used:

#define TOUCH_PIN PIN_B7
#bit TOUCH_PIN_BIT = 0xF81.7
