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

Button functions.
A A/B
A quick press changes from the active VFO to the non-active VFO. ie, VFO-A to
VFO-B,
or VFO-B to VFO-A.
A long press, copies the active VFO to the non-active VFO. ie, VFO-A to VFO-B,
or VFO-B to VFO-A.
B RIT / SPLIT
A quick press turns the RIT function on or off.
A long press, turns the split VFO function on or off.
C RPT
A quick press turns on the -RPT function, the next press turns on the +RPT
function, the next
press turns off the RPT function.
Holding the RPT button down, allows you to adjust the RPT offset for the
current VFO.
Each of the 30 VFO's has its own RPT offset.
The default RPT offset for the 10M VFO's is 100KHz.
" 6M VFO's is 1MHz.
" 2M VFO's is 600KHz.
" 70CM VFO's is 5MHz.
The default RPT offset for all other VFO's is 0.0KHz.
D MEM
A quick press turns the MEM function on, use the encoder to select a used
memory.
You can use any of the MEMORY mode keypad functions.
See "Button functions while in MEMORY mode" below.
Another quick press turns the MEM function off.
A long press, saves the current VFO to a memory, use the encoder to select a
memory to save to.

There are 202 memories to choose from. Memory 1 to 200 and M-PL and M-PU.
A quick press will cancel the memory save, and return you to the VFO
screen.
Or another long press will save to the selected memory. SAVING will be
displayed for 1.6 sec,
then you will be returned to the MEMORY mode screen. You can then use any
of the MEMORY
mode keypad functions. See "Button functions while in MEMORY mode" below.
Note:- M-PL and M-PU memories can be used to set the frequency limits
for a VFO scan.
M-PL = lower limit, M-PU = upper limit.
* STEP SIZE
Hold this button down to select the DDS step size.
The cursor will be turned on under one digit of the frequency display,
allowing you to select
a step size of 10Hz to 100MHz using the rotary encoder, further anti-
clockwise rotation of
the encoder allows you to select one of the preset step sizes shown below.
6MHz, 200KHz, 100KHz, 50KHz, 30KHz, 25KHz, 20KHz, 15KHz, 12.5KHz, 10KHz,
9KHz, 6.25KHz,
6KHz, 5KHz, 3KHz, 2.5KHz, 1KHz.
While holding down the * (STEP SIZE) button, if you press the # button you
can enable or
disable the RND (rounding) function. If rounding is enabled RND will be
displayed on the LCD.
When the * (STEP SIZE) button is released, the rotary encoder will step the
DDS frequency by
the step size. If rounding is enabled the frequency will be rounded to the
nearest whole
multiple of the step size.
Each of the VFO's has its own step size.
The default step size is 1KHz rounded, for all VFO's.
0 Start entering a frequency.
0 must be the first digit entered to start keypad frequency entry.
Any subsequent digits will be entered in front of the MHz decimal point.
If the * is entered, any subsequent digits will be entered after the MHz
decimal point.
The # is then used to accept the number entered.
i.e. to set a frequency of 21.25 MHz, enter 021*25#
# MENU
