USB_Polling_Proc
Prototype
void USB_Polling_Proc(void);
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(1) {
USB_Polling_Proc();
kk = HID_Read();
if (kk != 0) {
for(cnt=0; cnt < 64; cnt++)
writebuff[cnt]=readbuff[cnt];
HID_Write(&writebuff,64);
}
}
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).
Gen_Enable
Prototype
void Gen_Enable(char* readbuff, char* writebuff);
Description Initialize the USB module of the MCU.
Parameters - readbuff: Read Buffer.
- writebuff: Write Buffer.
Returns Nothing.
Requires USB needs to be enabled before using this function. See HID_Enable.
Example
Gen_Enable(&readbuff,&writebuff);
Notes None.
