Hi kan,

usb_device CDC example packet size = 32 bytes

how to:

modify package size 32 bytes to 64 bytes?

thanks,

Carlos.

Hi Carlos,

The packet size can be modified by changing the definition in usb.h. For example, EP0_SIZE.

Hope that helps,

Hi Kan,

What do I see acotece modified.

#define EP0_SIZE         64//  32

#define EP1_SIZE         64//  32

#define EP2_SIZE         64//  32

#define EP3_SIZE         64//  32

0x40 bMaxPcketSize

See

buffer[] = 64 bytes....

EP_IN_Transfer(EP2,CDC_OUTPointer, 64 );     01 not SEND buffer to PC

EP_IN_Transfer(EP2,CDC_OUTPointer, 64 );     02      SEND buffer to PC = 64 bytes ok

only the second time it sends the packet.

void EP_IN_Transfer(uint8 u8EP,uint8 *pu8DataPointer,uint8 u8DataSize) ( usb.c ) <----

Thanks,

Carlos.
