button) modes. Due to a typo in altimeter.xml, one direction of
adjustment with the left mouse button was giving fast changes.
Simple patch attached.
- Julian
twice the design size (character height) of the old one.
Advantages:
- displays . and : correctly with less space around, and digits
with more space around (using Andy's improvements to plib)
- small text becomes much more legible (-> clock, AP-altitude)
- the font contains pretty much every character that can be
displayed on a seven segment display, so it might be more
useful for future instruments.
It's a little funky to use right now because
the FRQ and timer buttons should be momentary action.
As it stands you need to do 2 clicks to send on/off.
If anybody can think of a workaround, we could use one.
For now the ADF and BFO buttons just toggle the
annunciators. For ANT mode, I just need to wire up the
ADF needle.
Two clicks on FRQ flip flops the selected and standby
freqs.
Two clicks of FLT/ET will change the standby display
to timer mode and another two will flip between
FLT and ET. If you click and the annunciator flashes
briefly but the display does not change, you need
to click FRQ -one time- to get the button in phase.
ET mode has a count down mode, this is where it really gets tricky.
On the real thing, you hold the SET/RST button for 2 seconds.
Here you must click one time, wait for the display to flash then
click one more time. Now you can set the time to count down.
Right clicking the dial will set minutes, middle click (I know,
I'll make it a keyboard modifier later) sets hours. As usual
the left side decreases and right side increases.
Once you have the desired time set, click the SET/RST button
twice in rapid succession. Two rapid clicks will reset the
elapsed timer when it's counting down, but also while you are
setting it (when display is flashing).
When the count down timer reaches zero, it starts counting up again.
It -should- flash for 15 seconds and set off a warning tone, but
for now it doesn't.
The unit is also equipped with an on/off/volume knob. Whne the
unit is powered down the timers are reset.

Add labeling

Prettier face
Since a while I get a line of black pixel garbage below the labels "WL" and
"ALT" on the autopilot. Does anybody else see this? (Or is it a feature of
my graphics card? :-) The following patch fixes this for me.
Jim sez:
This file contains the xml and updated rgb for an APR button on the
autopilot. It can be used to lock on to the glide slope on an
ILS aproach.
As it stands now the NAV locks onto the NAV1 localizer and the APR locks
on to the NAV1 GS (if it exists). I think (and I'm not quite sure) that on a
real autopilot (like the KAP-140) the NAV button will lock on to VOR signals
and the APR is used for locking to localizer/ils for both axiis. But without
having a manual and knowing exactly how this should work, and making further
changes to the autopilot code, this slight modification will make it easier to
lock onto a glideslope on approach.
