A lot of junk builds up in windows (not the least of which is the bloated os).? We have had work win machines get up over 100 com ports, but it gets annoying.? Clear the old ones out: I had a win 10 machine just finally slow down so much (disk access often hitting 100% for 15 minutes after boot), that I just got another dell and grumbled about lenovo quality control.? Then I needed a linux machine and decided to put a blank ssd in the old (not really that old) lenovo and load the mint distro.? Wow, what a nice os -- apparently there was nothing wrong with the lenovo (either windows corruption or maybe failing hard disk).? Every feature of the laptop worked out of the box with linux mint. ----- Original message ----- From: "Rob Giuliano via groups.io" <kb8rco=[email protected]> Subject: Re: [TinyTrak] TT USB not compatible with Windows 10 Date: Friday, August 06, 2021 7:29 PM A couple of items: 1. Windows 10 keeps track of every device that was ever connected, and just keeps incrementing ??? the COM# port ids.? Some 'older applications' like TeraTerm may only 'acknowledge' ports 1 - 9 or so. ??? In Device Manager, you can show hidden and clean out devices that are not in use, but are taking up ??? lower COM# numbers. 2. The TT4 provides feedback on initial boot up. You need to see this initial message in TeraTerm ??? This can be difficult with the TT USB cable as it powers the TT4 on J2 pin 4. ??? Three options here: ??? a) Open case and use the jumper for the TT4 pin 4 selection to cycle and reset the TT4 ??? b) Make sure the TT4 is not powered through the "Rado port' (J1 pin 7) and cycle power using J2 ??????? You cannot disconnect / reconnect the USB side because the TT4 is initiated ??????? before the PC sets up new COM# port and makes it active. ??? c) NOTE: carefully ground the Atmega chip reset pin - doesn't take much, just a touch to ground ??????? Kit version - Micro Pin 9 to ground Micro pin 11. ??????? PreBuilt version - micro pin 4, but no easy access.? ????????????? Schem references access on J5, but I don't see that connection on the board. NOTE about 2b:? Be very careful of the JP6.? ???? JP6 must be on Vcc - Make sure it is NOT Vin when connecting the TT USB cable.

I made sure I had installed the drivers from the Byonics website. Perhaps newer drivers already existed? I dunno. Anyways, I uninstalled all the drivers, reinstalled the drivers from Byonics, rebooted, and it is recognizes it now. At this point, I can't get TeraTerm to connect to it. It shows conncected in the COM port, but nothing displays in the terminal window. The only thing different from the quick start that I can figure is that I'm not connected to a radio right now. I was just figuring I could configure it first. Cycling the device by un-plugging and plugging it back in has resulted in several BSODs so far. Matt N8SHA |
