HID_Disable
Prototype
sub procedure HID_Disable()
Description Disables USB HID communication.
Parameters None.
Returns Nothing.
Requires USB HID needs to be enabled before using this function. See HID_Enable.
Example
HID_Disable()
Notes None.
USB_Interrupt_Proc
Prototype
sub procedure USB_Interrupt_Proc()
Description This routine is used for servicing various USB bus events. Should be called inside USB interrupt
routine.
Parameters None.
Returns Nothing.
Requires Nothing.
Example
sub procedure USB1Interrupt() iv IVT_ADDR_USB1INTERRUPT
USB_Interrupt_Proc()
end sub
Notes Do not use this function with USB_Polling_Proc, only one should be used. To enable servicing through
interrupt, USB_INTERRUPT constant should be set (it is set by default in descriptor le).
USB_Polling_Proc
Prototype
sub procedure USB_Polling_Proc()
Description This routine is used for servicing various USB bus events. It should be periodically, preferably every
100 microseconds.
Parameters None.
Returns Nothing.
Requires Nothing.
Example
while TRUE
USB_Polling_Proc()
kk = HID_Read()
if (kk <> 0) then
for cnt = 0 to 63
writebuff[cnt] = readbuff[cnt]
next cnt
HID_Write(@writebuff,64)
end if
wend
Notes Do not use this functions with USB_Interrupt_Proc. To enable servicing by polling, USB_INTERRUPT
constant should be set to 0 (it is located in descriptor le).
