9/25/2015 Grove Gesture v1.0 Wiki Gesture Library We have created a library to help you start playing quickly with the Seeeduino/Arduino, in this section we'll show you how to set up the library and introduce some of the functions. Setup 1. Download the library code as a zip file from the Gesture_PAJ7620 github page. (https://github.com/Seeed-Studio/Gesture_PAJ7620) 2. Unzip the downloaded file into your …/arduino/libraries. 3. Rename the unzipped folder "Gesture"(or:"Gesture_PAJ7620") 4.
9/25/2015 Grove Gesture v1.0 Wiki #include "paj7620.h" void setup() { paj7620Init(); } void loop() { uint8_t data = 0; // Read Bank_0_Reg_0x43/0x44 for gesture result.
9/25/2015 Grove Gesture v1.0 Wiki void setup() { paj7620Init(); } This initialization code should be added to each demo. 2. Read data from PAJ7620 register via I2C paj7620ReadReg(uint8_t addr, uint8_t qty, uint8_t data[]) addr: Register address qty: Number of data to read, addr continuously increase. data[]: The starting address(a variable or array) to store data. void loop() { uint8_t data = 0; // Read Bank_0_Reg_0x43/0x44 for gesture result.
9/25/2015 Grove Gesture v1.0 Wiki Gesture Examples/Applications These examples are going to show you how to recognize gestures from this Grove Gesture. Open File->Examples->Gesture(or:Gesture_PAJ7620)->example>paj7620_9gestures sketch for a complete example. Description: This example can recognize 9 gestures and output the result, including move up, move down, move left, move right, move forward, move backward, circleclockwise, circle-counter clockwise, and wave.
