Description

The sensor on Grove - Gesture is PAJ7620U2 that integrates gesture recognition function with general I2C interface into a single chip. It can recognize 9 gestures including move up, move down, move left, move right, etc with a simple swipe of your hand.

Following is a video which using Gesture sensor with matrix to display the direction of hand.

We can utilize the gesture to adjust the sound volume, control a robot. Or we can make a remote-control unit, which is able to operate many devices at the same time via a gesture sensor.

Hello. Looking into the PAJ7620U2 datasheet, it talks about &quot;Normal Mode&quot; and &quot;Gaming Mode&quot;. Looks like &quot;Gaming Mode&quot; operates 2x faster and follows up faster user action. But I could not understand which is the way to select one of these by I2C regisger read/write operation.

The sample library on github.com has initialization code that may be doing all the setup, but I am not sure if it is setting the chip into &quot;Normal Mode&quot; or &quot;Gaming Mode&quot;. If I look into the datasheet example, it is showing setup code example, but it is different from the github.com example, and also there is no comment onm what each reagistry setting is doing.

My question is: - Into which mode (Normal or Gaming) the github.com library is setting the chip? - If it is into Normal, then how can I set it to Gaming? - Both github.com library seems to be writing data into all of the registers including the registers I cannot find their meanings on datasheet. How can I know what all of them are doing?

- If I do only the operations described on datasheet, it should be OK to detect gestures? Namely: &amp;gt;Programing Sequence and Function Application &amp;gt;i. Initial &amp;gt;Step 1:Power On, The VBus must be power on before VDD. &amp;gt;Step 2:Wait 700us for PAJ7620U2 to stabilize. &amp;gt;Step 3:Write slave ID or I2C read command to process I2C wake-up. &amp;gt;Step 4:Write initial setting to gesture.

Hi Leandro~ You can use this sensor with Grove Pi+ ### https://www.seeedstudio.com/GrovePi%2B-p-2241.html ###. Here is the driver. ### https://github.com/DexterInd/GrovePi/tree/master/Software/Python/grove_gesture_sensor ### We recommend you use Grove pi+, cause it is simple and stable.But if you want to use this sensor with Raspberry Pi directly, you need to writh a driver (library) yourself.You can refer to the Arduino driver we offered in our wiki.Regards

Can we connect 2 gesture sensors on the same base shield?

Hi there~ Yes ,you can. However since the grove-Gesture sensor have the same I2C address, you need to use the software I2C,or there will be an address conflict.Regards

For the software I2C, you can download the library here ### https://github.com/loovee/Arduino_SoftI2C ###

Is this gesture sensor compatible with raspberry pi (Python language) ?
on Jul 03,2017
Reply upvote ()
Hi there~ Theoretically,it is compatible.However for some reason we do not have the library for Raspberry.There are two options: 1.You can use Grove Pi+### https://www.seeedstudio.com/GrovePi%2B-p-2241.html ### And here is the driver ### https://github.com/DexterInd/GrovePi/tree/master/Software/Python/grove_gesture_sensor ###. 2 You can write the python library yourself and use this sensor with Raspberry directlly.Regards
