This library is ment to interface between WinRad and the Elektor SDR through the FT-232R USB chip (May 2007). Always download the latest version of the library. The library is compiled with Borland C++ Builder 6.0 and you need to have the device drivers installed from www.ftdichip.com. If you want to help me improving this library, please send your comments to the WinRad mailing list.Installing the DLL:
Today (21 sept 2008), Andrea Weick send me an email to inform me of the work that he did to make de WinRad DLL compatible with the WinRad version 1.32. Hereby the text of his email, the DLL is in the download section.
|Version||Rel. Date||Changes made|
|1.32||21 Sept. 2008||Contriduted by Andrea Weick, this version should work on WinRad version 1.32|
|0.9-2||14 Oct. 2007||Mario (DG0JBJ) informed me that he found two errors in the library.
The first was a small frequency offset (circa 800Hz on 4MHz, 1.2KHz on 6MHz, 2.3Khz on 12MHz) in the LO frequency. I have corrected this with a fixed capacitor load value of 0x90 (appr. 13pF) in the clock generator, this fixed the frequency offset for me (checked with some well-known SW broadcast stations by the lack of a frequency counter). Later i will add a frequency calibration routine so you can fine-tune your Xtal.
The second was a big frequency shift and strange mix results above the 12.5 MHz LO frequency. This was caused due to a too-low DIV1N value (2) in the clock generator although i used the fixed /2 divider for high frequencies. After re-reading the datasheet i now set the not-used DIV1N divider to the save value (8).
[UPDATE! - 7 dec 2007] I finally found out what went wrong with the compile of the library. I got a couple of mails from people who informed me that they are missing different run-time libraries when running the DLL while i was shure that i commanded the linker to build a static library. It seems that there is another checkbox on a different tab that should also be deselected. I updated the libraries in both 0.9-2 zip files and hope this problem is solved now.
|0.9-1||22 Sep. 2007||Alberto (I2PHD) pointed out to me that the previous version was compiled whitout runtime libraries so it will only run on pc's with C++ Builder installed. This version is linked with runtime libraries included.
Also i enabled the windowborder again and disabled the StayOnTop option. The previous version only positioned correctly on 1280x1024 screens and there was no way to reposition the window. I'm still thinking of a nice way to tackle this, anyone have an idee?
