Install without openplotter

[Vincent Hure]

Is it possible to use MacArthur Hat with Pi OS lite and signalk?
Need driver?

Best regards

I think it's possible, but you'd be one your own to find the right device tree settings to enable all the serial ports and the SPI bus and driver settings for CAN/NMEA2000.

A starting point would be to setup OpenPlotter and see how it configures /boot/firmware/config.txt of the Raspberry Pi.

Thank you
Look difficult without documentation.

yes, it's possible
/boot/firmware/config.txt
for pi5

Code:

dtparam=i2c_arm=on
dtparam=spi=on
dtoverlay=mcp251xfd,spi0-1,oscillator=20000000,interrupt=25
dtoverlay=w1-gpio,gpiopin=19
dtoverlay=uart2-pi5
dtoverlay=uart4-pi5

for pi4

Code:

dtparam=i2c_arm=on
dtparam=spi=on
dtoverlay=mcp251xfd,spi0-1,oscillator=20000000,interrupt=25
dtoverlay=w1-gpio,gpiopin=19
dtoverlay=uart3
dtoverlay=uart5

Everything you can do in Raspberry Pi OS that does not require a desktop environment can be done in Raspberry Pi OS Lite. No driver required.

What BlackSea has sent enables I2C, SPI, CAN, 1W, and UART2 and 4, but other OpenPlotter features are still missing. OpenPlotter just makes easy to edit the config.txt file so my advice would be to enable and configure OpenPlotter following your necessities and then copy that config.txt file to Raspberry Pi OS Lite. Or you can also examine OpenPlotter's code to see what it is done for every setting.

Same advice for Signal K.

Thank you for your useful explanation
