How to use on Arduino

  • Step 1: Download the test program
  1. Download the Arduino test program from the Program Download column
  2. 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
  1. Plug the module directly into the Arduino development board ( Do not plug in?)
  2. After the module is plugged in, power on the Arduino board
  • Step 3: Copy the dependent library
  1. Make sure the Arduino IDE is installed on your computer (if it is not installed: Arduino IDE download URL)
  2. 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
  1. 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
  1. 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):
