💾 l3xz-pressure-sensor-firmware

Firmware for the L3X-Z pressure sensor which is based on the CyphalPicoBase/CAN board.

Schematic for conversion circuit

How-to-build/upload

arduino-cli compile -b rp2040:rp2040:rpipico -v .
arduino-cli upload -b rp2040:rp2040:rpipico -v . -p /dev/ttyACM0

or

arduino-cli compile -b rp2040:rp2040:rpipico -v . --build-property compiler.cpp.extra_flags="-DCYPHAL_NODE_INFO_GIT_VERSION=0x$(git rev-parse --short=16 HEAD)"

Adding argument --build-property compiler.cpp.extra_flags="-DCYPHAL_NODE_INFO_GIT_VERSION=0x$(git rev-parse --short=16 HEAD)" allows to feed the Git hash of the current software version to 107-Arduino-Cyphal stack from where it can be retrieved via i.e. yakut.

How-to-yakut

Install and configure yakut:

. setup_yakut.sh

Obtain pressure sensor value via yakut (cyphal.pub.pressure_0/1.id = 6001, 6002):

y sub 6001:uavcan.si.unit.pressure.Scalar.1.0 --with-metadata
...
y sub 6002:uavcan.si.unit.pressure.Scalar.1.0 --with-metadata
