EXAMPLE
This example shows how the USB functions are used.
This example first initializes the USB peripheral, which
allows the host to enumerate the device. The enumer-
ation process occurs in the background, via an Inter-
rupt
Service
Routine.
This
function
waits
until
enumeration is complete, and then polls EP1 OUT to
see if there is any data available. When a buffer is
available, it is copied to the IN buffer.
Presumably
your application would do something more interesting
with the data than this example.
; ******************************************************************
; Demo program that initializes the USB peripheral, allows the Host
;
to Enumerate, then copies buffers from EP1OUT to EP1IN.

main
call
InitUSB
; Set up everything so we can enumerate
ConfiguredUSB
; wait here until we have enumerated.
CheckEP1
; Check Endpoint 1 for an OUT transaction
bankisel

; point FSR to our buffer

; check end point 1
call
GetUSB
; If data is ready, it will be copied.

; was there any data for us?
goto
PutBuffer
; Nope, check again.
; Code host to process out buffer from host

FSR
; point FSR to our buffer

; put 8 bytes to Endpoint 1
call
PutUSB
btfss
STATUS,C
; was it successful?
goto
PutBuffer
; No: try again until successful
goto
idleloop
; Yes: restart loop

ASSEMBLING THE CODE
The code is designed to be used with the linker. There
is no provision for includable files. The code comes
packaged as several different files:
USB_CH9.ASM - handles all the Chapter 9 com-
mand processing.
USB_DEFS.INC - #Defines used throughout the
code.
USB_MAIN.ASM - Sample interrupt service
routine.
HIDCLASS.ASM - Handles the HID class specific
commands.
10.9.8.1
Assembly Options
There are two #defines at the top of the code that con-
trol assembly options.
10.9.8.2
#define ERRORCOUNTERS
This define includes code to count the number of
errors that occur, by type of error. This requires extra
code and RAM locations to implement the counters.
10.9.8.3
#define FUNCTIONIDS
This is useful for debug. It encodes the upper 6 bits of
USWSTAT (0x197) to indicate which function is exe-
cuting. See the defines in USB_DEFS.INC for the
codes that will be encoded.
