Homebrew 3 Channel Pure SIN Generator ( 0 ... 60MHz )

[Yucca]

Just finished writing a double buffered graphics API in C++ for the NOKIA 3310 LCD screen:

I am moving to this screen instead of the NOKIA 6610 screen because:

its cheaper.
it seems easier on the eye than the 6610 screen.
it will make case layout and installation easier because the screen board has 4 nice mounting holes on it.

Awesome!

Cheers stprue,

I've finished the main freq screen and also decided on the layout for the main menu.

FREQU TUNING:
Gives the main frequency screen where user is able to adjust any decade of any channel.

PHASE TUNING:
Gives the phase screen where user is able to adjust phase of any channel.

LIN SWEEPING:
User is able to set start and end points of a linear sweep and also specify the number of milliseconds that the sweep should take. The unit will output a trigger signal from a fourth BNC connector so a scope can be hooked up and used as a frequency response monitor for the coil under test.

LOG SWEEPING:
As above only the sweep is logarithmic, sweep step is proportional to frequency.

HARMONIC LOC:
User can set multiplication factors for f2 and f3. For example if f2 is set to 2.000 and f3 is set to 3.000 we will get the first and second harmonic. When harmonic lock is active the main freq screen will show a small padlock in bottom right. Then if the user sets say f1 to 1MHz then f2 and f3 will automaticly go to 2MHz and 3MHz. Of corse any multiplication factors can be entered.

At the moment it will be 1D sweeping, In the future I will expand to 3D sweeping by putting a second level into the sweep menus and maybe combining LIN and LOG into one item to give me another menu position (any ideas for another menu function are welcome)
