Configure Raspberry Pi

Enable I2C Interface

Open a terminal and run the following commands:

sudo raspi-config 
Choose Interfacing Options -> I2C -> Yes.

Reboot Raspberry Pi:

sudo reboot

Enable SPI interface

PS: If you are using a system with a Bullseye branch, you need to change "apt-get" to "apt", and the system of the Bullseye branch only supports Python3.

Open the terminal, and use the command to enter the configuration page.

sudo raspi-config
Choose Interfacing Options -> SPI -> Yes  to enable the SPI interface

Reboot Raspberry Pi：

sudo reboot

Make sure that the SPI is not occupied by other devices, you can check in the middle of the /boot/config .txt.

Enable UART

Execute the following command to enter the Raspberry Pi configuration:

sudo raspi-config

Choose Interfacing Options -> Serial -> No -> Yes:
You need to disable the login shell and enable the srial port hardware:

Reboot Raspberry Pi:

sudo reboot

Open the /boot/config.txt file and find the following configuration statement to enable the serial port, if not, add it at the end of the file:

enable_uart=1

Reboot to take effect.

Install libraries

Install Library

If you use the bookworm system, you can only use lgpio library, bcm2835 and wiringPi can't be installed and used.

BCM2835

#Open the Raspberry Pi terminal and run the following command
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.71.tar.gz
tar zxvf bcm2835-1.71.tar.gz 
cd bcm2835-1.71/
sudo ./configure && sudo make && sudo make check && sudo make install
# For more, you can refer to the official website at: http://www.airspayce.com/mikem/bcm2835/

WiringPi

#Open the Raspberry Pi terminal and run the following command
cd
sudo apt-get install wiringpi
#For Raspberry Pi systems after May 2019 (earlier than that can be executed without), an upgrade may be required:
wget https://project-downloads.drogon.net/wiringpi-latest.deb
sudo dpkg -i wiringpi-latest.deb
gpio -v
# Run gpio -v and version 2.52 will appear, if it doesn't it means there was an installation error

# Bullseye branch system using the following command:
git clone https://github.com/WiringPi/WiringPi
cd WiringPi
. /build
gpio -v
# Run gpio -v and version 2.70 will appear, if it doesn't it means there was an installation error

lgpio

#Open the Raspberry Pi terminal and run the following command
wget https://github.com/joan2937/lg/archive/master.zip
unzip master.zip
cd lg-master
sudo make install

# You can refer to the official website for more: https://github.com/gpiozero/lg

Control sensors by Serial port

Configure Serial Port

1) Open a terminal and run the following commands:

sudo nano /boot/cmdline.txt

Change the line below：

wc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

to:

dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4
elevator=deadline rootwait

Save and exit (Ctrl+X， Y)
2) Run the following command：

sudo nano /etc/inittab

Modify the line below:

#Spawn a getty on Raspberry Pi serial line
T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

to:

#Spawn a getty on Raspberry Pi serial line
#T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

Save and exit (Ctrl+X， Y)
3) Reboot Raspberry Pi:

sudo reboot

After rebooting, the hardware serial of Raspberry Pi is enabled and the login shell function is disabled. If you want to access Raspberry Pi via serial port, you need to reset all the setting and reboot.

Print data via serial Port

1) Users should configure the jumpers on board for enable serial port:

Connect CP_RX to P_TX
Connect CP_TX to P_RX

2)Run putty software in host PC and configure:

Serial line: Select the COM port according the Devive Manager

sudo make
sudo ./serialTest

The serial port will print data as below:

Set up a wireless network with 2 Xbee modules

Preparation

1) Two Xbee modules
2) Two ARPI600 modules
3) Two Raspberry Pi

接口说明

接口概述

1) 默认情况下，Arduino接口数字控制脚对应树莓派IO如下：

Arduino接口	树莓派IO
D0	P_RX
D1	P_TX
D2	P0
D3	P1
D4	P2
D5	P3
D6	P4
D7	P5
D8	P6
D9	P7
D10	CE0
D11	MOSI
D12	MISO
D13	SCK

2) 模块电路板上有配置APRI600的D11, D12, D13管脚的跳线。它们之间通过0Ω电阻短接。如下图所示：

出厂时跳线连接如下：

SCK连接D13
MISO连接D12
MOSI连接D11

如果连接：

D13连接P26
D12连接IO_SD
D11连接IO_SC

则相当于使D11, D12, D13管脚接到树莓派普通IO控制脚。
注意：用户可以根据需要更改这些跳线，但是此操作需要用到焊接器材。在没有我司工作人员指导下擅自更改，将视为放弃保修。
3) APRI600的A0-A5管脚可以配置为IO控制功能或者ADC功能。

a) 当A0-A5连接到 1处时，则A0-A5作为IO控制管脚，和树莓派管脚对应关系参见下表：

Arduino接口	树莓派IO
A0	CE1
A1	P5
A2	P6
A3	P7
A4	CE0
A5	MOSI

b) 当A0-A5连接到 3处时，则A0-A5作为AD转换脚。
4) 用户可以连接A4和P_SCL，A5和P_SDA（如图 22.），以作为树莓派的I2C控制脚，默认断开。
注意：用户可以根据更改这些跳线，但是此操作需要用到焊接器材。在没有我司工作人员指导下擅自更改，将视为放弃保修。
