![]() ![]() I attach my macro file for anyone who'd want to use it as a starting point in trying a similar approach. A lot of stuff is hard coded that might be made more flexible with some more time. So I set up this macro to sweep from 100 to 1200 Hz in 50 Hz steps and save it to a file which I'd then import into Excel. I have a passive audio filter for CW with a BW of about 500 Hz centered on 550 Hz or so. Using this library it is possible to make better use of VT100 capable terminal programs such as Tera Term. Select the appropriate COM port from the drop down box and then press OK. Open Tera Term and select the Serial radio button. (Most recently to talk to my HP-48G calculator.) Tera Term looks pretty good for that and I made up a simple macro after a few hours of trial and error on the commands. Library to control a VT100 terminal via an Arduino. If Tera Term is not installed, it can be downloaded and unzipped by clicking on the link below: Install Teraterm 4.60.zip (Save file to desktop then install) Loopback - No Lantronix Box. I've been using something called Tera Term or maybe Tera Term VT for cases were I needed a serial terminal. ![]() ![]() I considered writing a serial app from scratch but decided to see if any terminal program I have would have a full-featured enough macro language to allow doing it in a macro. ![]()
