Description

The Pmod GYRO module integrates the robust STMicroelectronics L3G4200D MEMS gyroscope, designed for high shock survivability and precise measurement of angular rate across three axes. Its digital output provides calibrated data, eliminating the need for external signal conditioning and simplifying integration into embedded control systems.

Engineered for flexibility, the module supports both SPI and I2C serial protocols, allowing developers to select the optimal interface for their application. Configurable parameters include scale range, output data rate, and built-in high-pass/low-pass filtering, enabling fine-tuning for specific motion detection scenarios, from slow tilting to rapid rotational movements.

Frequently Asked Questions

What is the operating voltage for the Pmod GYRO module?

The Pmod GYRO module is designed to operate at 3.3V DC, which is the standard voltage level for the Digilent Pmod ecosystem. Always ensure your host board (such as an FPGA or microcontroller development system) provides a compatible 3.3V power supply on the Pmod connector to avoid damaging the sensitive MEMS sensor IC.

How do I choose between the SPI and I2C communication interfaces?

The interface is selected via the CS (Chip Select) pin. Pulling the CS pin high enables the I2C interface mode. Pulling CS low selects the 4-wire SPI mode. The module's pinout is clearly defined for both protocols. SPI generally offers higher maximum data rates, while I2C can save microcontroller pins in multi-device setups.

Can I use this module with an Arduino or Raspberry Pi?

Yes, but it requires a compatible adapter or host board with a 12-pin Pmod connector or careful manual wiring to the correct GPIO pins. The module operates at 3.3V logic levels, so direct connection to a 5V Arduino requires level-shifting for the data lines. Libraries and example code are available from Digilent to facilitate integration with various platforms.

What is the purpose of the two interrupt pins?

The two interrupt pins (INT1 and INT2) on the L3G4200D are fully configurable. They can be programmed to trigger events such as data-ready signals (indicating new measurement data is available), motion detection alerts when a predefined angular rate threshold is exceeded, or for FIFO watermark/overrun notifications, allowing for efficient, interrupt-driven system design.
