I am trying to understand how to open and use multiple FTDI devices in the same program.
I am using *ftdi_usb_find_all()* to enumerate the devices and then *ftdi_usb_open_dev()* to open each one and identify it. Afterwards I close each device. I do this part with just one ftdi_context. Now that I found all the devices I want to open each selected device and keep it open for reading and writing. I notice that *ftdi_context* contains the following: - libusb_device_handle - readbuffer - eeprom All this makes me believe that I need a separate *ftdi_context* for each device that I want to access. Am I on the right track? Using the *ftdi_device_list* that I found above I want to create a new context for each device and open it. I tried doing ftdi_new(); ftdi_usb_open_dev(); for each device using the old device list. But I get a SIGSEGV somewhere in the depths of usb_open() in libusb. I am thinking it is because I used a device list created with one context and now am trying to open the same device using a different context. So how do I accomplish what I want? Any advice would be appreciated. Regards Ales Fiala -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details. To unsubscribe send a mail to [email protected]
