Utilization
Requirements
This shield can only be used with a development board or shield that provides
a configuration for Grove System connectors with Grove Digital Layout
and defines a device tree phandle grove_gpios as an
Laced Grove Signal Interface.
Programming
Set -DSHIELD=grove_btn_dX when you invoke west build, wherein X
corresponds to the ordinal number of a signal from the
Laced Grove Signal Interface. For example:
Using west:
west build -b mimxrt1060_evkb -p auto -d build/helloshell-seeed_grove_base_v2-grove_btn_d4 bridle/samples/helloshell -- -DSHIELD="seeed_grove_base_v2 grove_btn_d4"
west flash -d build/helloshell-seeed_grove_base_v2-grove_btn_d4
Using CMake and ninja:
# Use cmake to configure a Ninja-based buildsystem:
cmake -Bbuild/helloshell-seeed_grove_base_v2-grove_btn_d4 -GNinja -DBOARD=mimxrt1060_evkb -DSHIELD="seeed_grove_base_v2 grove_btn_d4" bridle/samples/helloshell
# Now run ninja on the generated build system:
ninja -Cbuild/helloshell-seeed_grove_base_v2-grove_btn_d4
ninja -Cbuild/helloshell-seeed_grove_base_v2-grove_btn_d4 flash
