I am simulating a simple code using atmel's spi libraries for At91sam7x256 in keil debugger. For days i have been trying to get the simulation running but i can see no signal change on Spi clock and signal pins in the virtual osciloscope. I can see however that the chip select signal is changing levels but there is no change of signals on MOSI and SPCK pins. Supposing everything else is correct about the code (i mean initialization) is this normal?

The following on-chip peripherals are not simulated. ... Serial Peripheral Interface
So perhaps as expected. Does your code work in real life?
Thanks for the reply. I expected that but since the chip select was changing level i was starting to doubt weather there was something wrong with the code. I haven't tried the code on the hardware yet. i was just testng every feature of the code so obsessively. i see no reason why it shouldn't work.
