Hi. My name is Nicola.I'm working with a DNP 9200 rev2 card but I have problems with the memory mapping addresses that do not correspond to the ATMEL free use library available. In principle, addressing PORT A I can control the PORT C of my DNP/SK25 demo kit and anyway I cannot operate with the SPI port.
Can someone help me?
My project is written in C.
I'm using the registers definitions (from atmel files),I map the registars to physical memory, I start the cpu & peripheral clock, than I start the SPI interface clock and I
try to write data to the peripheral, without any response.
Can someone help me?
I cal send the code to give a look to my prjoject .
Bye.
Nicola
