Re: A83: Defining SendAByte and RecAByte


On the TI-83 Plus:

Rec1stByte equ 4EFAh
Rec1stByteNC EQU 4EFDh
RecAByteIO EQU 4F03h

The article I forwarded contains the calls for the TI-83.

Here's an example of what you want


#ifdef TI83
#define bcallSendAByte ld (Asm_Ind_Call),11d \ call _IO_EXEC
#endif
#ifdef TI83P
#define bcallSendAByte bcall(SendAByte)
#endif

This is used by:
	ld a,10
	bcallSendAByte

This assumes that ion.inc has already been included, you assemble with the
standard ION method, and that the equates have already been defined.  You
should be able to figure out the rest.

I want to be able to just write the "bcall(SendAByte)" and then have the computer load 11d into Asm_Ind_Call and call _IO_EXEC for me on the TI83 and on the TI83 plus call the location 4EE5h.  If this is possible, can someone please tell me how to do it?  A brief example would be nice.  Also, could anyone please provide me with the TI83 plus equate for RecAByte?  Thanks.
