1.a. Supported Operating Systems

<p>We support using the Orangutan SVP&#8217;s USB connection under Microsoft Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10, Linux, and Mac OS X 10.7 (Lion) or later. The Orangutan SVP&#8217;s USB connection can be used to program the AVR, communicate directly with the AVR from a computer, or communicate with TTL-level serial devices from a computer.</p> <p>In Linux, the three virtual COM ports created by the SVP should appear as devices with names like <code>/dev/ttyACM0</code>, <code>/dev/ttyACM1</code>, and <code>/dev/ttyACM2</code> (the numbers depends on how many other ACM devices you have plugged in) and you can use any terminal program (such as <code>kermit</code>) to send and receive bytes on those ports.</p> <p>In Mac OS X 10.7 (Lion) or later, the three virtual COM ports created by the SVP should appear as devices with names like <code>/dev/tty.usbmodem00022381</code>, <code>/dev/tty.usbmodem00022383</code>, and <code>/dev/tty.usbmodem00022385</code> and you can use any terminal program (such as <code>screen</code>) to send and receive bytes on those ports. The lowest number found in the device names is the Orangutan SVP&#8217;s serial number.</p> <div class="note"> <p><strong>Mac OS X compatibility:</strong> we have confirmed that the Orangutan SVP&#8217;s USB connection works on Mac OS X 10.7 (Lion) and we can assist with advanced technical issues, but most of our tech support staff does not use Macs, so basic support for Mac OS X is limited.</p> <p>There is an issue that prevents the Orangutan SVP from working with macOS 10.11 or later.</p> </div> <p class="note"><b>Note:</b> You may not need to use the Orangutan SVP&#8217;s USB connection. If you have an AVR ISP programmer, then you can program the AVR on the Orangutan SVP by connecting your programmer to the 6-pin AVR ISP header located near the SVP&#8217;s USB connector. In that case, the operating system of your computer does not matter as long as it is compatible with your programmer.</p>
