Home /  Courses And Programs / Embedded Systems Hardware Interfacing

This course explores the most popular interfaces

used in embedded systems. Key interfaces covered include GPIO, ADC, Serial/UART, I2C, SPI and USB. Popular RF Technologies used in embedded systems are also covere, including Wi-Fi, Bluetooth, and NFC. Students will gain hands-on experience utilizing an STM32 IoT Discovery Node throughout the course.

Course Highlights:

  • Covers both wired and wireless embedded interfaces
  • Interfacing at both the physical and protocol layer
  • Useful case studies guided by hands-on exercises

Course Learning Outcomes:

  • Connect and program GPIO for reading digital inputs and writing digital outputs
  • Connect devices that output analog signals and use analog-to-digital conversion (ADC)
  • Connect Serial/UART devices and use them for both input and output
  • I2C and SPI devices, understanding their range, and connecting them to an embedded system
  • Embedded designs and USB devices
  • Incorporate Wi-Fi into an embedded system
  • Connecting BLE devices to embedded systems
  • Understand various RF options for embedded systems
