Minikits AD9954 User manual

Mini-Kits
HF RADIO v1.0
When first turned on, the software name and version number is displayed on line 1 and 2
of the LCD.
During power-up the PIC checks to see which DDS board is fitted.
The last digit of the version number indicates the DDS chip type found i.e.
version x.x0 If no DDS is found.
version x.x1 If an AD9851 is found.
version x.x2 If an AD9954 is found.
version x.x3 If an AD9958 is found. (note:- disabled in this version until fully
tested with the AD9958)
If no DDS board is connected to the PIC board, or the DDS chip type does not match the
calibration
settings saved in the PIC's EEPROM you will be taken to the DDS CALIBRATION screens. See
below.
After 2.5 second the VFO or memory screen is displayed.
The memory or frequency displayed is the same as that displayed before the power was
turned off.
Any changes are saved to EEPROM 3.3 seconds after the rotary encoder stops moving.
More descriptions to be added here. VFO's, DDS ranges, Bootloader, HRD control, etc

3 examples,
1) With DDS OFFSET = 0MHz.
With a LCD display frequency of 1MHz.
DDS frequency = ABS(1MHz + 0MHz) = 1MHz
With a LCD display frequency of 30MHz.
DDS frequency = ABS(30MHz + 0MHz) = 30MHz
2) With DDS OFFSET = 70MHz.
With a LCD display frequency of 1MHz.
DDS frequency = ABS(1MHz + 70MHz) = 71MHz
With a LCD display frequency of 30MHz.
DDS frequency = ABS(30MHz + 70MHz) = 100MHz
3) With DDS OFFSET = -70MHz.
With a LCD display frequency of 1MHz.
DDS frequency = ABS(1MHz + -70MHz) = 69MHz
With a LCD display frequency of 30MHz.
DDS frequency = ABS(30MHz + -70MHz) = 40MHz
Note :- The software will limit the DDS output frequency so that it is not
greater than
MAX DDS FREQ set in DDS CALIBRATION screen 7.
