AT89S8252, AT89S53 SPI Example Program

This example program shows how to configure and use the SPI in master mode for the following microcontrollers:

  • ATMEL AT89S53
  • ATMEL AT89S8252

To run this program...

  1. Choose your target
  2. Build the project (Project Menu, Build Target)
  3. Start the debugger (Debug Menu, Start/Stop Debug Session)
  4. View the Serial Window (View Menu, Serial Window #1)
  5. View the SPI peripheral (Peripheral Menu, SPI)
  6. View the Port 1 (Peripheral Menu, I/O Port)
  7. Display the memory area X:0x700000
  8. Run the program (Debug Menu, Go)

A debug script (SPI_AT250X0.ini) includes debugger signal functions that simulate an Atmel AT250X0 SPI memory device. This device is simulated using a simple state machine implemented with switch statements.
