Hi everybody!
         I am trying to set up SPI communications in my LPC1769. It is the first time I use SPI. The problem is that when I send data, all is ok except when I try to send 0x00. I use my oscilloscope and I can see the clock line and MOSI line switching as it shoulds when I send 0x01, 0x02, 0x03 and so on, but I see nothing when I send 0x00.

                         Somebody could help? Thanks in advance!!

Hi!

       The problem was my scope. I set the SCKL pin as the trigger source and now I am able to see how the uC is sending the byte 0x00.
                
                         Thank you for your help.

Hi,

Do you see the SPI CLK when you send 0x00 data ? Since data is 0x00, the data line will be low for the corresponding clock cycles.

Have you tried using LPCOpen examples ?
