Firmware for the L3X-Z leg controller.

How-to-build/upload

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

or

arduino-cli compile -b rp2040:rp2040:arduino_nano_connect -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 offset from sensor values and store in registers (with 42 being the node id):

y call 42 435:uavcan.node.ExecuteCommand.1.1 'command: 0xCAFE'

Read offset value via register interface:

y r 42 cyphal.l3xz-leg-ctrl.angle_offset_deg.b
87.5390625

y r 42 cyphal.l3xz-leg-ctrl.angle_offset_deg.a
