Detailed Description

Functions and macros for working with endpoints.

Define Documentation

#define RESETFIFO

(

ep

)

Value:

{FIFORESET=0x80; SYNCDELAY();\
                       FIFORESET=ep; SYNCDELAY();\
                       FIFORESET=0x00; SYNCDELAY();}

NOTE you can't use these unless you define SYNCDELAY as a macro or function. The reason is that SYNCDELAY needs to be longer or shorter depending on your IFCONFIG settings. See delay.h

Example:

  #define SYNCDELAY() SYNCDELAY4 // SYNCDELAY4 from delay.h

RESETFIFO should not use 0x80|epnum for IN endpoints Only use 0x02, 0x04, 0x06, 0x06 for ep value

#define RESETFIFOS

(

)

Value:

{FIFORESET=0x80; SYNCDELAY();\
                     FIFORESET=0x02; SYNCDELAY();\
                     FIFORESET=0x04; SYNCDELAY();\
                     FIFORESET=0x06; SYNCDELAY();\
                     FIFORESET=0x08; SYNCDELAY();\
                     FIFORESET=0x00; SYNCDELAY();}

Quickly reset all endpoint FIFOS.

		WORD	len
	)
