Opens the FTDI device with the specified description. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. FTDI (FTD2XX) component. You can read raw bytes from the serial interface using something like the following: At the end of the above, response will be an NSData instance containing the bytes you've read from the port. Most USB serial port drivers don't support flushing properly, probably because there's no way of knowing if there's still data in the internal shift register, FIFO or in the USB subsystem. You may also need to adjust the relative path that this library expects, in order for it to function within your app bundle, so you may need to run the following command against it at the command line: Once your project is all properly configured, you'll want to import the FTDI headers: and start to connect to your serial devices.
