Firstly regards the crash make sure you installed the 1.3 version of the driver, not the old one. You could download it directly from the Manufacturers Website in case they have issued an update since I wrote this page.
Usb-serial Ch340 Driver Windows 7 32bit Download
This driver will let you use USB to serial programmable devices with the ch340g/ch340c/ch314 chipsets. These programmable chips are used for small projects and some devices that have been converted for USB. There is a tutorial here on installation and other functions of the chip. If you are installing on a really old version of Windows such as Windows 98 make sure you install all the latest drivers for USB support, sometimes the unofficial Windows 98 Service packs are the best way. Devices using ESP8266 Chipset are often interfaced with the CH340 chip.
DriverGuide maintains an extensive archive of Windows drivers available for free download. We employ a team from around the world which adds hundreds of new drivers to our site every day. How to Install Drivers Once you download your new driver, then you need to install it. To install a driver in Windows, you will need to use a built-in utility called Device Manager. It allows you to see all of the devices recognized by your system, and the drivers associated with them.
The Driver Update Utility automatically finds, downloads and installs the right driver for your hardware and operating system. It will Update all of your drivers in just a few clicks, and even backup your drivers before making any changes.
The CP210x Manufacturing DLL and Runtime DLL have been updated and must be used with v 6.0 and later of the CP210x Windows VCP Driver. Application Note Software downloads affected are AN144SW.zip, AN205SW.zip and AN223SW.zip. If you are using a 5.x driver and need support you can download Legacy OS Software.
In the article, the link to which I gave you, there is a Windows 7/10 section. Just download CH341SER.exe and install the driver.There should be the following in Device Manager.I have several Arduino Nanos with CH340G. They all work well on Windows.
Not good at such close up photography Tom. I think it is a ATmega328p. Perhaps I have the correct drivers installed and It has no bootloader. The drivers that I keep ending up with are FTDI. Can't follow Boffin's advice because Windows 7 is sufficiently dumbed down not to allow homing in on the inf file from a driver package (manual installation) The FTDI drivers were chosen by windows, though I'd removed them completely so they seem to have been obtained automatically online. I've not had to do anything so tricky since years back on Windows 2000 and XP. Getting spanners on the nuts and bolts gets trickier as Windows dumbs itself down to the point where much less can be controlled by the user but we can change pretty colours and be awed by the magic. I posted the error message a while back when I try to load a sketch. Of course there will be problems if a bootloader has to be burned first. Another on order so I'll see where I go from there.
good day , I have an USB to UART adapter installingbased on the ch340G chip. I have installed the required driver but at the end the program says that it has been previously installed ( ? ! ). Windows does not recognise the adaptor and puts a yellow triangle on the control panel. Any help please ? Thanks Ambro
I have an uno r3 with ch340G which I can talk to from my home w7 x64 notebook after I have installed the drivers. On my desktop the drivers somehow do not communicate properly. If I plug in the device windows recognized it and shows port 8 as new port. When I try to transfer a sketch to the device it fails though with error message avrdude: stk500_recv(): programmer ist not responding. I have tried CH341s64.sys rev 3.3.2011.11 and 3.4.2014.8 without success 2ff7e9595c
