Seeed Studio Grove Interconnect Shields

Bridle supports a couple of different shields carrying Seeed Studio Grove System [7] connectors. Please download and read through the Preface - Getting Started [12] and Introduction to Grove [13] before use the product. Also have a look on the SiPEED Wiki page about the Grove standard interfaces [14].

Grove Base Shield

The Grove Base Shield [15] is an Arduino Shield that breaks out the Arduino pins to Grove connectors. Once you plug the Base shield on the Arduino, you will be able to plug a Grove module to one of the Grove connectors on the Base Shield. All I/O ports of the Arduino are exposed and adapted into Grove connectors which include digital I/O, analog I/O, and specialized ports (I2C, SPI, UART).

Versions

There are three versions, but nowadays only version 2 should be used actively. Here find the comparison between various versions of Grove Base Shield:

Grove Base Shield V2

Overview

Model: 103030000

The Grove Base Shield V2.1 [16] and Grove Base Shield V2.0 [21] board provides a simple way to connect with Arduino boards. This version 2 focuses on the simplicity of power supply.

SEEED_GROVE_BASESHIELD_V2

Power Compatible

Every Grove connector has four wires, one of which is the VCC. However, not every controller main board needs a supply voltage of 5V, some boards only need 3.3V. That’s why now a power toggle switch was add to this version so that one can select the suitable voltage of the controller main board using via this switch.

Pinout Diagram

The pinout of Base Shield V2 is the same as Arduino Uno R3 [1]. The shield usually has the same pin position as the Arduino development board and can be stacked and plugged into Arduino compatible boatds to implement specific functions.

Utilization

Laced Grove Signal Interface

All Grove Interconnect Shields provide their specific interface for general signal mapping, the Laced Grove Signal Interface.

Following mappings are well known:

  • grove_gpios: GPIO mapping

  • grove_pwms: PWM mapping

GPIO mapping

This is the GPIO signal line mapping from an Arduino Uno R3 [1] or Arduino Uno R2 [2] header bindet with arduino-header-r3.

Attention

On the NXP MIMXRT1010-EVK, resistors R793, R795 and R800 must be fitted for proper use. The Laced Grove Signal Interface overwrites the default settings of the board on the Arduino UNO R3 header and completes the missing PAD assignments for the signal lines D4, D5 and D9.

PWM mapping

Not all boards provide a dedicated PWM channel for the output of a variable average value of voltage or current over time on all digital lines. The corresponding mapping is always board or SOC specific. In addition to the PWM signal line mapping, the valid references to the PWM function units in the SOC or on the board are therefore also defined as Grove PWM Labels.

The following tables reflects the currently supported boards, but this list will be growing up with further development and maintenance. This list must not be complete.

This is based on the Zephyr board ST Nucleo F303RE and its arduino-header-r3.

Programming

Grove Base Shield

Set -DSHIELD=seeed_grove_base_v2 or -DSHIELD=seeed_grove_base_v1 when you invoke west build or cmake in your Zephyr application. For example:

  1. Grove Base Shield V2 on NXP MIMXRT1060-EVK:

    Using west:

    west build -b mimxrt1060_evkb -p --shield seeed_grove_base_v2 -d build/helloshell-seeed_grove_base_v2 bridle/samples/helloshell
west flash -d build/helloshell-seeed_grove_base_v2

    Using CMake and ninja:

    # Use cmake to configure a Ninja-based buildsystem:
cmake -Bbuild/helloshell-seeed_grove_base_v2 -GNinja -DBOARD=mimxrt1060_evkb -DSHIELD="seeed_grove_base_v2" bridle/samples/helloshell

# Now run the build tool on the generated build system:
