Grove Button Shields

Bridle supports a couple of different Button shields carrying Seeed Studio Grove System [1] connectors. Please download and read through the Preface - Getting Started [3] and Introduction to Grove [4] before use the product. Also have a look on the SiPEED Wiki page about the Grove standard interfaces [5].

Utilization

Requirements

This shield can only be used with a development board or shield that provides a configuration for Grove System [1] connectors with Grove Digital Layout [2] 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:

  1. Grove Base Shield V2 on NXP MIMXRT1060-EVK for GPIO driven Button on Grove D4:

    Using west:

    west build -b mimxrt1060_evkb -p --shield "seeed_grove_base_v2 grove_btn_d4" -d build/helloshell-seeed_grove_base_v2-grove_btn_d4 bridle/samples/helloshell
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 the build tool on the generated build system:
ninja -Cbuild/helloshell-seeed_grove_base_v2-grove_btn_d4 flash

  2. Grove Base Shield V1.3 or Grove Base Shield V1.2 on NXP MIMXRT1060-EVK for GPIO driven Button on Grove D4:

    Using west:

    west build -b mimxrt1060_evkb -p --shield "seeed_grove_base_v1 grove_btn_d4" -d build/helloshell-seeed_grove_base_v1-grove_btn_d4 bridle/samples/helloshell
west flash -d build/helloshell-seeed_grove_base_v1-grove_btn_d4

    Using CMake and ninja:

    # Use cmake to configure a Ninja-based buildsystem:
cmake -Bbuild/helloshell-seeed_grove_base_v1-grove_btn_d4 -GNinja -DBOARD=mimxrt1060_evkb -DSHIELD=""seeed_grove_base_v1 grove_btn_d4"" bridle/samples/helloshell

# Now run the build tool on the generated build system:
ninja -Cbuild/helloshell-seeed_grove_base_v1-grove_btn_d4 flash
