Preparation:
When installing the driver, you do not need to connect the board to the computer!
1. First you need to install the driver. The driver download address is:
2. Install USB to serial port driver
After downloading it to your computer, unzip it directly. After unzipping, double-click to run it.
Click Install and wait until "Driver pre-installation successful!" pops up, indicating that the driver installation has been completed. Click OK and close the installation interface
3. Install Arduino software, software download address: https://www.arduino.cc/en/Main/Software?setlang=cn
Inspection before use
Please wear anti-static equipment (such as an anti-static wrist strap) before using the board, or wash your hands first and touch the iron
The faucet has eliminated the static electricity on your body (static electricity can easily damage the chip or cause the boot program to be lost)
1. Connect to the computer with a USB cable and observe whether the indicator light "PWR" on the board is always on and whether the indicator light "L" flashes.
2. If "PWR" is always on, it means the power supply is normal. "L" flashes, which means the board is working normally (Blink is pre-downloaded before leaving the preogram)
If everything checks normal, you can start downloading the program for testing.
1. Open the Arduino software
2. Select a program and click: File → Example → 01.Basics → Blink
3. Select the development board model. Click in sequence: Tools → Development Board → Arduino Nano
4. Select a processor model. Click: Tools → Processor → ATmega328P (Old Bootloader)
The old version of Arduino software only has ATmega328P, and there is no ATmega328P (Old Bootloader).
For this option, ATmega328P should be selected at this time. As long as there is the option ATmega328P (Old Bootloader), then be sure to select this option, not ATmega328P! Otherwise, the program will not be downloaded.
5. Select a port number. Right-click "Computer", select "Manage", and select "Device Management" in the pop-up menu.
"Manager", click the triangle symbol in front of "Port" on the right menu, find USB-SERIAL CH340, and the COM port at the back is the port number
6. Program burning
First click the program compilation button "√". If there is no problem with the program, the software will prompt "Compilation completed".
After the program is compiled, click the download button
When you see the message "Upload successful" below the software, it means that the program has been successfully downloaded to the development board. You're done!
