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.

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:

L76X GPS Module rpi serial.png


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

#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

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
  • Connect CP_TX to P_RX

2)Run putty software on the host PC and configure:

  • Serial line: Select the COM port according to the Device Manager.
  • Speed: Set the baud rate to 9600.
  • Connection type: Choose Serial.

3) Copy the program/Xbee/send the folder to Raspberry Pi and go into send folder, run the following commands:

sudo make
sudo ./serialTest

The serial port will print data as below:

You can only choose one setting when configuring the REF voltage.
3) Copy the program/AD_TLC1543 folder to Raspberry Pi and go into it. Run the following commands

sudo make
sudo ./tlc1543

4) The data sent from AD0 pin will be printed.
5) Connect the T_A0 pin to A0, then you can connect the A0 pin to any sensors for Analog signal reading:

sudo nano tlc1543.c Find the line:
re=ADCSelChannel(0); Change 0 to other numbers of pin for testing other AD pins (for example re=ADCSelChannel(1);
Save and exit (Ctrl+X, Y).
2) Run the following commands to test:

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: You can change the setting of resistors. (Please confirm it with Waveshare first if you want to change it, otherwise, the board loses the warranty.
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: You can change the setting of pins. (Please confirm it with Waveshare first if you want to change it, otherwise, the board loses the warranty.
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.
