The cpp wrapper also has problems when the device does not have a serial
number.
The following code was run with a single usb device attached. The device
does not have a serial number:
#include "ftdi.hpp"
#include <iostream>
#include <iomanip>
int main(int argc, char **argv)
{
int vid = 0x0403, pid = 0x6010;
Ftdi::Context context;
Ftdi::List *list = Ftdi::List::find_all(context, vid, pid);
for (Ftdi::List::iterator it = list->begin(); it != list->end(); it++)
{
std::cout << "Test1 " << it->vendor() << ", " << it->description()
<< std::endl;
std::cout << "Test2 " << it->vendor() << ", " << it->description()
<< std::endl;
std::cout << "Test3 " << it->vendor() << ", " << it->description()
<< ", " << it->serial() << std::endl;
std::cout << "Test4 " << it->vendor() << ", " << it->description()
<< ", " << it->serial() << std::endl;
std::cout << "Test5 " << it->vendor() << ", " << it->description()
<< ", " << it->serial() << std::endl;
}
delete list;
return EXIT_SUCCESS;
}
Program output:
Test1 Lattice, Lattice FTUSB Interface Cable
Test2 Lattice, Lattice FTUSB Interface Cable
Test3 Lattice, Lattice FTUSB Interface Cable,
Test4 $ $ $ $ C s , Cable,
Test5 $ $ $ $ C s , Cable,
Once it->serial() has been accessed, it->vendor() and it->description()
have been corrupted.
