Labs

This course will involve 7 labs (delivered through 10 lab sessions) and 2 tutorials. The topics of the labs are:

• Lab 1: Embedded C and Timers

• Lab 2: Serial Communication Interface (SCI)

• Lab 3: Using Inter-Integrated circuit (I2C) to communicate with an LCD

• Tutorial A: Interfacing microcontroller to FPGA

• Tutorials B: HCS12 Bus Timing

• Lab 4: Demultiplexing and decoding

• Lab 5: Interfacing external bus with Switches and LEDs

• Lab 6: Interfacing external bus with Keypad

• Lab 7: Interfacing external bus with RAM

The labs used the MC9S12DP512 microcontroller. Next year, we will move to a newer microcontroller "STM32G491RE" which is manufactured by STMicroelectronics based on Arm Cortex-M4 32-bit RISC architecture family.
