Posted on October 05, 2013 at 22:03Hi;
I am working on the Custom HID application which is in the St library and I use STM3210E-EVAL. But this protocol transfer only 2 bytes (1 Byte Id + 1 Byte Data) so I modified the code and I transferred the 64 bytes from host (pc) to device (eval board) but I didn't send more than 2 bytes from device to host.Finally, I want to send 64 bytes from device to host. Can you help me?
These are my changings ;
at usb_prop.c
....
SetEPTxCount(ENDP1, 2); --> SetEPTxCount(ENDP1, 64);
SetEPRxCount(ENDP1, 2); --> SetEPRxCount(ENDP1, 64);
....
at usb_desc.c
const uint8_t CustomHID_ConfigDescriptor[CUSTOMHID_SIZ_CONFIG_DESC] =
{
....
....
0x02 changed to 0x40 /*vMaxpacketsize endpoint address IN*/
....
....
0x02 changed to 0x40 /*vMaxpacketsize endpoint address OUT*/
....
....
}
const uint8_t CustomHID_ReportDescriptor[CUSTOMHID_SIZ_REPORT_DESC] =
{
....
....
/* Led 1 */
0x85, 0x01, /* REPORT_ID (1) */
0x09, 0x01, /* USAGE (LED 1) */
0x15, 0x00, /* LOGICAL_MINIMUM (0) */
0x25, 0x01, /* LOGICAL_MAXIMUM (1) */
0x75, 0x08, /* REPORT_SIZE (8) */
0x95, 0x01, changed to 0x95, 0x40 /* REPORT_COUNT (1) */
...
...
}
I also increased the SendBuffer size to 65.
Thanks...
