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.

• 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

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.

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:

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 the as GPIO pins or AD pins.
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 are works 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.
5) The pins for sensors are extended in the ARPI600 board:

• 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.
