Hello. I am using KEIL uVision2 (V2.10). I want to simulate SPI port on 89S8252 / 89S53. I am following the instructions on KEIL website help link: http://www.keil.com/download/docs/at89s8252_spi.zip.asp It states: 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) I have chosen the correct device through the dialog box, however it DOES NOT show an option for SPI peripheral in the Peripheral Menu. Please tell me what I am doing wrong ?? Regards Aman
You are using an old version. The current release is C51 V7.07 which comes with uVision2 V2.39.
You should update your C51 installation to a current version.
