Zoom Value is Capped Too Low

[schacon]

visca_cli only accepts up to a 1024 zoom value, but my D70p will accept values in excess of 15000 - 1024 is barely zoomed in at all.

Dear Hi
I am using PIC MICROCONTROLLER

In this function I can't understand WriteFile function,because of this
function your code in not working in my compiler.

uint32_t
_VISCA_write_packet_data(VISCAInterface_t iface, VISCACamera_t camera,
VISCAPacket_t packet)
{
DWORD iBytesWritten;

WriteFile(iface->port_fd, packet->bytes, packet->length,
&iBytesWritten, NULL);
if ( iBytesWritten < packet->length )
return VISCA_FAILURE;
else
return VISCA_SUCCESS;
}
2nd doubt In this function I can't understand ReadFile *function,because
of this function your code in not working in my compiler.

uint32_t
_VISCA_get_packet(VISCAInterface_t *iface)
{
int pos=0;
BOOL rc;
DWORD iBytesRead;

// wait for message
rc=ReadFile(iface->port_fd, iface->ibuf, 1, &iBytesRead, NULL);
if ( !rc || iBytesRead==0 )
{
// Obtain the error code
//m_lLastError = ::GetLastError();
_RPTF0(_CRT_WARN,"ReadFile failed.\n");
return VISCA_FAILURE;
}
while (iface->ibuf[pos]!=VISCA_TERMINATOR) {
if ( ++pos >= VISCA_INPUT_BUFFER_SIZE )
{
// Obtain the error code
//m_lLastError = ::GetLastError();
_RPTF0(_CRT_WARN,"illegal reply packet.\n");
return VISCA_FAILURE;
}
rc=ReadFile(iface->port_fd, iface->ibuf + pos, 1, &iBytesRead, NULL);
if ( !rc || iBytesRead==0 )
{
// Obtain the error code
//m_lLastError = ::GetLastError();
_RPTF0(_CRT_WARN,"ReadFile failed.\n");
return VISCA_FAILURE;
}
}
iface->bytes=pos+1;

return VISCA_SUCCESS;
}
rest of thing are understandable
