Library to talk to FTDI chips. You find the latest versions of libftdi at
- http://www.intra2net.com/en/developer/libftdi/
+ https://www.intra2net.com/en/developer/libftdi/
The library is easy to use. Have a look at this short example:
\include simple.c
return 0;
}
+/**
+ Return device ID strings from the eeprom. Device needs to be connected.
+
+ The parameters manufacturer, description and serial may be NULL
+ or pointer to buffers to store the fetched strings.
+
+ \param ftdi pointer to ftdi_context
+ \param manufacturer Store manufacturer string here if not NULL
+ \param mnf_len Buffer size of manufacturer string
+ \param product Store product description string here if not NULL
+ \param prod_len Buffer size of product description string
+ \param serial Store serial string here if not NULL
+ \param serial_len Buffer size of serial string
+
+ \retval 0: all fine
+ \retval -1: ftdi context invalid
+ \retval -2: ftdi eeprom buffer invalid
