How to use on Arduino
- Step 1: Download the test program
- Download the Arduino test program from the Program Download column
- For a description of the relevant test procedures, please refer to the test program documentation in the package
- Step 2: Connect the Arduino development board
- Plug the module directly into the Arduino development board ( Do not plug in?)
- After the module is plugged in, power on the Arduino board
- Step 3: Copy the dependent library
- Make sure the Arduino IDE is installed on your computer (if it is not installed: Arduino IDE download URL)
- After installing the Arduino IDE, you need to copy the dependent library to the Arduino project directory as follows:
- (1) Decompress the downloaded test package
- (2) Copy the dependent libraries in the Install libraries directory in the package (shown below) to the libraries folder
- of the Arduino project directory ( Don't know the Arduino project directory?)
- Step 4: Compile and download the program to the development board
- Open the sample in the Example directory of the package to test, compile and download( Don't know how to compile and download?)
- Step 5: Observe the running of the program
- After the program is downloaded, run it directly and observe the running status. If it can be displayed normally, the program runs
- successfully, as shown in the following figure (take the colligate_test test program as an example):
