Hello, laxhead94.
Here is some example C++ code for Maestro+libusb from a post by CarrotSnack, slightly modified by me:
#include <iostream>
#include <libusb-1.0/libusb.h>
#include "protocol.h"
using namespace std;
bool deviceMatchesVendorProduct(libusb_device *device, unsigned short idVendor, unsigned short idProduct)
{
libusb_device_descriptor desc;
libusb_get_device_descriptor(device, &desc);
return idVendor == desc.idVendor && idProduct == desc.idProduct;
}
void setTarget(int position, int servo)
{
const unsigned short vendorId = 0x1ffb;
unsigned short productIDArray[]={0x0089, 0x008a, 0x008b, 0x008c};
libusb_context *ctx=0;
libusb_device **device_list=0;
libusb_init(&ctx);
int count=libusb_get_device_list(ctx, &device_list);
for(int i=0;i<count;i++)
{
libusb_device *device=device_list[i];
{
for(int Id=0;Id<4;Id++)
{
if(deviceMatchesVendorProduct(device, vendorId, productIDArray[Id]))
{
libusb_device_handle *device_handle;
libusb_open(device, &device_handle);
libusb_control_transfer(device_handle, 0x40, REQUEST_SET_TARGET, position*4, servo, 0, 0, (ushort)5000);
libusb_close(device_handle);
break;
}
}
}
}
libusb_free_device_list(device_list, 0);
libusb_exit(ctx);
}
int main()
{
while(1)
{
int position;
int servo=0;
cout << "Enter position: ";
cin >> position;
setTarget(position, servo);
}
return 0;
}Please note that one flaw of the code above is that it does not check any of the return codes provided by the libusb functions so it will be hard to debug if something goes wrong.
Even though this code was written for Linux, I think it will work with minimal modification on a Mac. You will need to download, build, and install Libusb. Then should be able to compile the code above either in XCode or with a command like:
c++ test.cpp -lusb-1.0 -o testGood luck. Let us know if you have any problems.
