产品详情

The Analog Devices Active Learning Module - Low-Speed Mixed Signal Playground (ADALM-LSMSPG) facilitates hands-on exploration of software-hardware interfacing concepts. It consists of two 8-channel multifunction ADC/DAC/digital GPIOs - AD5592r and AD5593r - which have SPI and I2C interfaces, respectively. The AD5592r includes a simple NPN transistor curve tracer circuit as a representative instrumentation application. The AD5593r includes a PNP curve tracer, and both devices include bi-color "Hello, World!" LEDs. An LM75 temperature sensor is also included as a "bare minimum" peripheral example. The ADALM-LSMSPG is compatible with Raspberry Pi and Feather form factor hosts, and an ADALM2000 interface allows monitoring of the SPI and I2C busses for driver development and debug.

Example scripts and source code are provided for Linux, no-OS (bare-metal), and Zephyr applications.

APPLICATIONS

  • Hands-on learning about Linux device drivers and application software
  • Hands-on learning about no-OS / bare metal device drivers
  • Hands-on learning about Zephyr drivers and applications
  • Hands-on learning about SPI and I2C interface debugging
