Old version kbd.c
PostPosted: Tue Sep 06, 2005 10:52 am     Reply with quote
Dear PCM compiler:

I am using an old PCM compiler (version 2.7.1) The kbd.c file in the examples folder start with this line:
#define kbd =6

I found a new version keypad driver (kbdd.c) which start as follow:

#if defined(__PCH__)
#if defined use_portb_kbd
#byte kbd = 0xF81 // This puts the entire structure
#else
#byte kbd = 0xF83 // This puts the entire structure
#endif
#else
#if defined use_portb_kbd
#byte kbd = 6 // on to port B (at address 6)
#else
#byte kbd = 8 // on to port D (at address 8)
#endif
#endif

#if defined use_portb_kbd
#define set_tris_kbd(x) set_tris_b(x)
#else
#define set_tris_kbd(x) set_tris_d(x)
#endif

I copied the new keypad driver into the example folder but my PCM compiler cannot compile it. The error happens at (__PCH__).

What I intend to do is using a keypad on port C. In the old keypad driver I changed the first line to:
#define kbd = 7
I also changed all “set_tris_b” into “set_tris_c”. But it does not work.

It looks like your setup is expecting the PCH compiler, where you have PCM. Try deleting the first line: #if defined(__PCH__), and then set use_portb_kbd to TRUE

Wrong, that's a test to see which compiler and then use the right registers!

Testing which compiler?

But... my compiler cannot compile the driver.

I deleted everything at top and just put 2 lines:


Quote:

#byte kbd = 7
#define set_tris_kbd(x) set_tris_c(x)


It works perfectly !!

Before this I just tried using 2 pull-up resistors because I have no enough 10k, it will work only i put all 4 pull-up resistors on row pins.
