I am having problems with the AD9833 using a PIC18F2550 and the Microchip C18 Compiler. I seem to be able to load the Control register OK, because I
Am able to turn the output of the DDS on and off. But I can't change the output frequency it remains at 3.124616 Mhz regardless of what frequncy
value I try to load. I have attached my code and screen shot of the SPI lines (CLK and DATA). I am using 25 Mhz MCLK and hex values from app note
AN-1070. Any help would be much appreciated.
