Re: Mouse issue after rpi-update

This fix worked for me! I'm running a Raspberry Pi 2 connected to a Avocent Cybex KVM which is connected to a Logitech K360 wireless keyboard and mouse.

8 Apr 2019

Thanks!

Re: Virtual Desktop with RealVNC

Hello, I'm using a Raspberry Pi 3 connected to the 7" touchscreen display. Unfortunately, most GUIs are too big for the small resolution provided by the touchscreen display (800x480) making some applications unusable. The easy workaround is to use a virtual VNC desktop session over the network for l...

Hello,

I'm having the same issue with getting my TP-Link Archer T2UH USB Wi-Fi adapter to work. The link in the solution post doesn't work any more. Any chance someone could provide a working like to that file?

Re: RS-232 RTS voltage levels?

Hello, I spoke with Yaesu's service department regarding the PTT trigger. They said that PTT is activated when the microphone is shorted (grounded). I've cobbled together a drawing using the Yaesu FT-60 manual's drawing (pg 11), k6vug's drawing [k6vug], and a drawing from the Yaesu MH-34B4B speaker/...

Re: RS-232 RTS voltage levels?

Hello Hippy, As luck would have it, I have a Prolific PL2303 cable on-hand for consoling Cisco devices : ) I agree that probably any pin capable of providing a signal could trigger the PTT, assuming the PTT can be triggered by a 3.3v signal. I'm not sure what options are available within the SoundMo...

Re: RS-232 RTS voltage levels?

Hello Burngate,

Thank you for the great explanation! I've e-mailed Yaesu asking for the PTT trigger signal level. Hopefully it's not above the 3.3v the Pi provides.

If the trigger requires something higher than the 3.3v I suppose I'll try my luck with a USB to RS-232 adapter.

Thanks again,

Rob
