Subject: [BITX20] TSW Teensy 4.0 software with RTC Now available #ubitx #v6
TSW Just released our latest software for the Teensy 4.0 to NANO adapter on the V6 uBITX.
Cleaned it up cosmetically so the on screen buttons look more like buttons, but that's just cosmetics. In this version, which will be the last for some time, we added an A>B touch button that does just that, copies the contents of VFO A into VFO B and makes them equal in preparation for operating SPLIT. All you have to do is tune VFO B the short distance to where you want to transmit after using A>B so you have a close, known starting spot.
The biggie though is the on-screen real time clock. It's displayed in the upper left corner of the main screen and if you touch anywhere in the clock display area, it brings up a menu for setting the time (HH:MM:SS) and has self explanatory text in the setting window. The main problem though is unless the user connects a 3 Volt battery between the "Vbat" pad (+3V) and ground on the Teensy 4 itself, you will have to reset the clock each time you power up the uBITX. We have been unable to find a usable 3V coin cell holder with the right pin spacing to match the Vbat and ground pads on the Teensy so finding a 3V cell with wire leads is suggested. It goes without saying the cell should be completely insulated so it doesn't short out to any components or grounded parts on the chassis or PC boards.
In testing, the RTC in the teensy appears to keep time reasonably well. It doesn't stay on to the second, but doesn't drift that much either. Over a portable session, the time should stay well within 30 seconds or so over a couple of hours.
When the setting menu is active, transmit is inhibited, but the receiver is active which makes it convenient to tune in one of the WWV frequencies or any available time standard like CHU, JJY and the like to allow fairly close setting of the seconds.
Anyway, it is V1.05 and it's available on the TSW website (www.w0eb.com <> ) in the "Files" section. Attached here is the accompanying software instruction manual to go with the program (manual also included in the downloadable zip file on the website).
Have fun with it folks. Thanks for your support.
