Page 4: Hardware Installation
PiCAN FD GNSS Rev C 1.0 • Communicate to the Pi via UART or I2C • PPS output to GPIO06 • Can work as a standalone using on board USB-C connection 2 Hardware Installation Before installing the board make sure the Raspberry is switched off. Carefully align the 40way connector on top of the Pi. Use spacer and screw (optional items) to secure the board. 2.1 Screw Terminals The CAN connections are made via the 4way screw terminals. Function CAN_L CAN_H GND n/c Note : The +12v In is only used on the PiCAN board with SMPS option fitted. SK Pang Electronics Ltd Ó 2022 www.skpang.co.uk... -

7DF#0201050000000000 This will send a CAN ID of 7DF. Data 02 01 05 – coolant temperature request. To send a CAN FD message with BRS use : cansend can0 7df##15555555555555555 To send a CAN FD message with no BRS use : cansend can0 7df##05555555555555555 Connect the PiCAN to a CAN-bus network and monitor traffic by using command: candump can0 You should see something like this: 5 Python Installation and Use Ensure the driver for PiCAN FD is installed and working correctly first. Clone the pythonCan repository by: git clone https://github.com/hardbyte/python-can cd python-can sudo python3 setup.py install Check there is no error been displayed.

Page 8: Gps Gnss Usage
6.1 Communicate over UART To use the UART port ensure SB6 and SB7 are made. The default baudrate is 9600 8-N-1. To do basic UART test on the Raspberry Pi, type in: stty -F /dev/ttyS0 raw 9600 cs8 clocal cat /dev/ttyS0 You should now see the GNSS/GPS sentences like this: 6.2 Communicate over I2C To use the I2C port ensure SB4 and SB5 are made. First install I2C tool: sudo apt-get install i2c-tools Now check I2C port: sudo i2cdetect -y 1 Check address 0x42 has shown up. SK Pang Electronics Ltd Ó 2022 www.skpang.co.uk... -

PiCAN FD GNSS Rev C 1.0 Now download the i2c python script from Github: https://github.com/skpang/Raspberrypi_i2c_gps Start the script by: python3 i2c-gps.py You should now see the GNSS/GPS sentences over I2C like this: 6.3 Communicate over USB The PiCAN FD GPS board can function as a standalone and communicate over USB. This requires an USB-C cable plug into the board. The USB-C also provides power to the board. This can be plugged into a PC. On a Windows PC, u-center can be used: Firmware update for the GPS/GNSS can also be done over USB.
