Where do I connect the CH340 to my computer?

Where do I connect the CH340 to my computer?

Connect the CH340 to your computer’s USB port. Click on somewhere else on the screen for the menu to refresh itself. Then head back to the menu by clicking on Tools > Port. A new COM port should pop up. By process of elimination, the CH340 should have enumerated to the new COM port!

Do you need crystal oscillator for CH340 G?

The CH340 G requires an external crystal oscillator to function while the CH340 C includes a built-in crystal oscillator. However, both function in the same fashion – they convert USB data for a serial UART and vice versa! The CH340 is also populated on development boards such as the RedBoard Qwiic to upload code using the Arduino IDE.

What kind of chip is in the Arduino Nano?

The origional Arduino NANO boards are getting very difficult to find these days and you may find yourself in posession of one of the newer Arduino compatiable NANOs with teh CH340G chip on the bottom (instead of the origional FTDI chip). Here is a great instructable that explains how to install the drivers and the differences.

How to install CH340 drivers in sparkfun.com?

Make sure to test the drivers before class and set aside some time with students in the classroom when installing the drivers. Download and run the executable. Click the “Uninstall” button first. Then click on the “Install” button.

What can CH340 do in serial port mode?

In the serial port mode, CH340 provides commonly used MODEM contact signals, which are used to expand asynchronous serial ports for computers, or to directly upgrade common serial devices to USB bus. In infrared mode, CH340 can form a USB infrared adapter by adding an infrared transceiver to realize SIR infrared communication.

What are the functions of the CH340 chip?

CH340 is a USB bus adapter chip. Its functions include USB to serial port and USB to IrDA infrared or USB to printer port. Ref: CH340 In the serial port mode, CH340 provides commonly used MODEM contact signals, which are used to expand asynchronous serial ports for computers, or to directly upgrade common serial devices to USB bus.

When is a port in err-disabled state?

err-disabled port: When a port is in error-disabled state,the port LED is set to the orange color and when you issue the show interfaces command, the port status shows as Errdisabled. Switch# show interface gigabit0/1 GigabitEthernet0/1 is down, line protocol is down (err-disabled)
