Overview

Introduction

The ARPI600 is an adapter board compatible with Raspberry Pi, Arduino, and XBee. It's used to expand commonly used interface resources and is a crucial part of the Internet of Things (IoT). The Raspberry Pi 4 Model B sensor kit includes the ARPI600 along with 13 commonly used sensors and sample demos. These resources help you get started quickly.

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

RPI open i2c.png

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

RPI open spi.png
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.

  • Check /boot/config.txt, and you can see 'dtparam=spi=on' was written in.

  • To make sure SPI is not occupied, it is recommended to close other drivers' coverage. You can use ls /dev/spi* to check whether SPI is occupied. If the terminal outputs /dev/spidev0.1 and /dev/spidev0.1, SPI is not occupied.

Enable UART interface

Open the Raspberry Pi terminal and enter the following command to enter the configuration interface 

sudo raspi-config
Select Interfacing Options -> Serial, disable shell access, and enable the hardware serial port

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 settings and reboot.

  • Print data via serial port

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

  • Connect CP_RX to P_TX

Interface

Pinout

1) The Arduino-compatible interface onboard is related to the GPIO of Raspberry:

Arduino Compatible Interface Raspberry Pi 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) You can configure the SPI interface by changing the setting of the 0ohm resistor as below:
ARPI600 15.png
The resistors are solders by default:

  • SCK is connected to D13.
  • MISO is connected to D12.
  • MOSI is connected to D11.

If you change the resistors as below:

  • D13 to P26.
  • D12 to IO_SD.
  • D11 to IO_SC.

The D11, D12, and D13 pins are connected to the GPIO of Raspberry Pi directly.
Note: Users can change these jumpers accordingly, but this operation requires soldering pads. Do not modify it without the guidance of our support team, otherwise, the warranty will be deemed waived.
3) The A0~A5 pins are configurable, you can configure them as GPIO pins or AD pins.
ARPI600 16.png
a) If A0~A5 pins are connected to 1, they are used as GPIOs:

Arduino interface Raspberry Pi IO
A0 CE1
A1 P5
A2 P6
A3 P7
A4 CE0
A5 MOSI

b)If the A0~A5 is connected to 3, they work as AD pins.
4) You can connect A4 to P_SCL and A5 to P_SD for connecting I2C devices. They are disconnected by default.
Note: Users can change these jumpers accordingly, but this operation requires soldering pads. Do not modify it without the guidance of our support team, otherwise, the warranty will be deemed waived.
ARPI600 17.png
5) The pins for sensors are extended in the ARPI600 board:
ARPI600 18.png

  • The pins (A6-A10) in A area are connected to TLC1543 chip for analog signals.
  • The pins in D are connected to the P0-P4 IO of Raspberry Pi for digital signal.

You can connect sensors to these pins.
