DJ Mixes — as 'DJ LeftCtrl'.Most recent sets from a DJ who started spinning records in 1998 in San Francisco. Having played techno and trance back then, LeftCtrl spins mostly house – deep, electro-swing, funky, tech and progressive. Ruby. C/C/Objective-C.
Arduino/Hardware. BASH. Updated Nov, 2017 with the latest driver for OS-X High Sierra. Updated Oct, 2016 with the new signed driver for OS-X Sierra. Updated Nov 22, 2015 with the new signed driver for OS-X El Capitan and Yosemite. Updated Jan 9, 2016 with Windows DriversMy golden rule is that if something took me longer than 15 minutes to figure out, then it's worth documenting in a tiny blog post so that it would save time to others, just like many other similar posts saved me million hours by providing simple clear instructions.Introduction – What is CH340G?
Recent versions of cheap Chinese have been coming with a different USB/Serial chip, which replaces the usual FTDI. I read somewhere that licensing costs of FTDI make it prohibitive to companies selling boards for as little as $3, so I assume this is the main motivation. To be honest, as long as I can talk to my Arduino and buy it for $3 a piece, who cares?:)Below you'll find links to drivers for both Windows and Mac to make these work. Please leave a comment, if it worked or didn't work for you, especially if you had to do anything special or hacky to make it work:)WindowsA fully signed drivers for Windows can be found below:.Mac OS-XHigh Sierra(Added: November, 2017)Looks like the updated version from their site works now as is.
Here is the updated cached locally, but for other platforms, please checkout.Sierra(Added: October, 2016)The Version 1.3 of the driver available on the vendor's website causes a crash on Mac OS-X Sierra. Thankfully, patched the driver, and made it available to the public.
The updated and patched Sierra Mac Driver can be downloaded here —. Pre-InstallationNote: the following pre-installation steps are only required on the two most recent versions of OS-X Yosemite and El Capitan.
It is because the driver is not signed properly from Apple's perspective. We are waiting on the developer to update the driver so that these pre-installation steps are no longer needed.OS-X El Capitan Steps (only for the older driver!)These are not needed for the newer driver above. Reboot and press ⌘-R immediately after the chime to enter Recovery Mode. Open Terminal from the recovery mode. run the command csrutil enable -without kext. Reboot. See if youwish to know more details.Installation.
Download the driver from here:. Double click the ZIP file do unzip it. Open the folder /Downloads/CH341SERMAC. Run installer found in that folder. Restart when asked.UsageIf the driver properly loaded, you should see the device in you /dev folder (this is for advanced command-line users of OSX only).
On my machine it was called /dev/cu.wchusbserial1441140This port is showing up correctly in Arduino 1.0.6 and Arduino 1.5.8.However, if you are using the Eclipse Plugin, it is not smart enough to list this port in the list of available serial ports (either in project properties, or in the serial monitor). You will have to type the entire thing yourself: /dev/cu.wchusbserial1441140 and then Eclipse can upload your sketch.That's it! You should be ready to use the drivers and the board.References.
I am working with an Arduino Uno clone that uses the CH340G USB to TTL converter in lieu of the 16U2 found on the Uno. I see that most tutorials suggest downloading the CH340G drivers from what they call. I don't quite trust that site, is there any more trustworthy website where one might be able to acquire CH340G drivers for a modern Linux distro (preferably CentOS or Debian).I ask here because. If the unix stackexchange site would be a better place to ask then the question can be moved. Thank you.EDIT: Apparently my system is having an issue with recognizing the device.

Indeed, you should not download drivers from random websites for a Linux system, not only as matter of safe practices but also because it is unlikely that they would be usable. USB serial converters for Linux are handled by kernel modules and those need to be compiled for the specific kernel in use or its close relative. Modern Linux distros likely support the CH340G already as the driver is included in the official kernel source, if not you should pursue obtaining a suitable kernel module from the provider of your distro or get the upsteam or distro kernel sources and compile the module.–Jan 6 '17 at 17:16.
Linux doesn't need drivers (indeed, the whole concept is pretty alien to Linux users).The CH340G is fully supported by the default kernel in all distros I have ever used.
