# rcwl-0516-driver
rcwl-0516-driver is a java library that operates microwave presence sensor called [RCWL-0516](https://www.epitran.it/ebayDrive/datasheet/19.pdf) to connect RCWL-0516 to GPIO terminal of Raspberry Pi 3B and make it for use in java.
I releases this in the form of the Eclipse plug-in project.
You need Java 8 or higher.
I use [Pi4J](https://pi4j.com/)
for gpio communication in java and have confirmed that it works in Raspberry Pi 3B ([Raspbian Buster Lite OS](https://www.raspberrypi.org/downloads/raspbian/) (2019-07-10)).
## Connection of RCWL-0516 and Raspberry Pi 3B
**Connect with `Vin <--> Vin`,`GND <--> GND`, `OUT <--> PWM`.**
- `Pins` of [RCWL-0516](https://www.epitran.it/ebayDrive/datasheet/19.pdf)
- Vin
- GND
- OUT
- [GPIO of Raspberry Pi 3B](https://www.raspberrypi.org/documentation/usage/gpio/README.md)
- Vin --> (2) or (4)
- GND --> (6), (9), (14), (20), (25), (30), (34) or (39)
- PWM --> (12) GPIO18, (35) GPIO19, (32) GPIO12 or (33) GPIO13
**Note. (12) GPIO18 and (32) GPIO12 cannot be used to generate different PWM signals at the same time.
Similarly, (35) GPIO19 and (33) GPIO13 cannot be used to generate different PWM signals at the same time.
Therefore, as an example, when (12) GPIO18 is in use, (32) GPIO12 cannot be used, but instead, either (35) GPIO19 or (33) GPIO13 can be used.**
## Install Raspbian Buster Lite OS (2019-07-10)
The reason for using this version is that it is the latest as of July 2019 and [BlueZ](http://www.bluez.org/) 5.50 is included from the beginning, and use Bluetooth and serial communication simultaneously.
## Configuration of Raspbian Buster Lite OS
- Edit `/boot/cmdline.txt`
```
console=serial0,115200 --> removed
```
- Edit `/boot/config.txt`

When editing is complete, reboot.
## Install WiringPi Native Library
Pi4J depends on the [WiringPi](http://wiringpi.com/) native library by Gordon Henderson.
The Pi4J native library is dynamically linked to WiringPi.
```
# apt-get update
# apt-get install wiringpi
```
When using with Raspberry Pi 4B, install the latest version as follows.
Please refer to [here](http://wiringpi.com/wiringpi-updated-to-2-52-for-the-raspberry-pi-4b/).
```
# wget https://project-downloads.drogon.net/wiringpi-latest.deb
# dpkg -i wiringpi-latest.deb
```
Please make sure it’s version 2.52.
```
# gpio -v
gpio version: 2.52
```
**Note. In October 2019, I have not confirmed the official information that can use Raspberry Pi 4B with Pi4J and WiringPi.
I've simply checked that it works, but some problems may occur.**
## Install jdk8 on Raspberry Pi 3B
For example, the installation of OpenJDK 8 is shown below.
```
# apt-get update
# apt-get install openjdk-8-jdk
```
## Install git
If git is not included, please install it.
```
# apt-get install git
```
## Use this with the following bundles
- [SLF4J 1.7.26](https://www.slf4j.org/)
- [Pi4J 1.2 (pi4j-core.jar)](https://github.com/s5uishida/pi4j-core-osgi)
I would like to thank the authors of these very useful codes, and all the contributors.
## How to use
The following sample code will be helpful.
```java
import com.pi4j.io.gpio.Pin;
import com.pi4j.io.gpio.RaspiPin
import io.github.s5uishida.iot.device.rcwl0516.driver.RCWL0516Driver;
import io.github.s5uishida.iot.device.rcwl0516.driver.IRCWL0516Handler;
public class MyRCWL0516 {
private static final Logger LOG = LoggerFactory.getLogger(MyRCWL0516.class);
public static void main(String[] args) {
RCWL0516Driver rcwl0516 = RCWL0516Driver.getInstance(RaspiPin.GPIO_18, new MyRCWL0516Handler());
rcwl0516.open();
// if (rcwl0516 != null) {
// rcwl0516.close();
// }
}
}
class MyRCWL0516Handler implements IRCWL0516Handler {
private static final Logger LOG = LoggerFactory.getLogger(MyRCWL0516Handler.class);
private static final String dateFormat = "yyyy-MM-dd HH:mm:ss.SSS";
private static final SimpleDateFormat sdf = new SimpleDateFormat(dateFormat);
@Override
public void handle(String pinName, boolean detect, Date date) {
LOG.info("[{}] {} {}", pinName, detect, sdf.format(date));
}
}
```
