Folks...

Thanks to the continuing efforts of Charles Skerry, we have a new version of the Garmin radar overlay PlugIn for OpenCPN.

In Charles' words:

New features:

1. Use NMEA-SENTENCES to acquire true heading values at any HZ. Tested with 5 HZ HDG from the AP.

2. Store the heading with each scan packet.

3. Use stored heading to align display for each packet.

These improvements provide a stable display when the boat heading is changing.

4. Change the display rendering from using scan byte values to using scan bits. This provides a sharper and more detailed display.

5. Improve rotated vp rendering.

Great work, Charles. This version provides a meaningful improvement in appearance, performance, and usability to the GRadar PlugIn.

A prebuilt Windows binary is attached, adorned as usual.

Thanks again, Chuck.

Good luck to testers.

Please describe your installation with a little more detail.

1. Is the switch in the cable installed?

2. Have you set up the address on your interface connection? Please post a screenshot.

Read through the old posts. Others have been down this road.

Good luck

Chuck

Thanks Chuck for your reply... I may sound quite amateur...well I am...

You said

1. Is the switch in the cable installed?

Hmmm wich switch are we talking about here (amphenol c**-5780?)... I tought a direct connection in my pc would do...

2. Have you set up the address on your interface connection? Please post a screenshot.

I have not done because I had no idea we had to do it and I have no idea how to do it

3. Read through the old posts. Others have been down this road.

I swear I did but it is sooooo long that i could not find in one chunk the whole process... and well... did not understand most of it... Maybe one of you could post a complete guide for total dummy... :-)
