Re: Send Integer to PC with usbMsgPtr

For example you could do this. Remember: "setupData" needs to be at least 8 bytes.
On the host side you again could decode the single bytes together to an int.

usbMsgPtr = (usbMsgPtr_t)setupData;
switch (rq->bRequest) {
[...]
case PSCMD_CALL_GETBUFFERSIZE: {
setupData[0] = rq->bRequest;
setupData[1] = PSCMD_RETN_OKAY;
setupData[2] = (singlebuffersize)&0xff;
setupData[3] = (singlebuffersize)>>8;
cli();
[...]

Best regards
