I am using an LPC1769. I am just trying demo USB_HID code. The demo sends 4 byte to PC. When I try to increase buffer size as 64 byte, the program does not working after that. I could not capture any data from PC.
What I need to do for sending 64 or 128 byte or more data to PC. I could not achieve it. I would like to send bulk data to pc. Please help me?
When I set REPORT_SIZE = 4 it is working, but when I increase it > 4 byte, the program is not working.
static int iCount;
static int fill = 0;
_iFrame++;
if ((_iFrame > 10000)) {
// send report (dummy data)
for(fill= 0; fill <16; fill++)
{
abReport[fill] = fill;
}
iCount++;
USBHwEPWrite(INTR_IN_EP, abReport, REPORT_SIZE);
_iFrame = 0;
}
Thak you very much for your replies..
