Hi All,

KD8CEC software will run in a stand-alone separate Arduino Nano which is not connected to a uBITX.

I have had occasions where I needed to look at the CAT serial link, so I mounted a spare Nano on
perfboard so I could access the UART RX and TX lines, as well as the Nano Reset line, and installed
the KD8CEC software on it. Test jig shown here:



and note the ESD ground plate underneath!

Some time ago I? purchased a Saleae 8ch logic analyzer when they were still cheap. I used it, and enjoyed it for about a year.

Then, an ESD accident blew the Saleae. I looked online and did not like the new Saleae prices, so I purchased a cheap
Saleae clone for about $12. See



Unfortunately, the folks at Saleae got upset at all the clones, and changed their software so that it would not work with the clones.

So, I went to the USBee web site to get software, only to find out they wanted $20 for it. I did not want to pay $20 for
proprietary software linked to one piece of hardware only.

After some digging I found what appears to be excellent open source (FREE!) logic analyzer software called? PULSEVIEW and sigrok.

PULSEVIEW provides for decoding protocols, such as I2C, UART, CAN, 1wire, and many more.

Sigrok is the command line version, and PULSEVIEW is the GUI on top of the command line
that provides a graphical display of decoded serial link.

PULSEVIEW/sigrok supports an impressive list of hardware analyzers. Furthermore, PULSEVIEW/sigrok supports
data collection from some digital mulit-meters, and digital oscilloscope dongles...see:



Apparently some logic analyzers have an analog channel, and PULSEVIEW can show the analog signal as you would see it on an oscilloscope.

Here is an example PULSEVIEW screen showing a UART serial link decoded.
Channel D0 is Nano UART RX, channel D1 is Nano UART TX, channel D2 is Nano reset line:

Not bad for a $12 investment!!

PULSEVIEW/sigrok installation instructions:

WINDOWS:

???

LINUX:

I use Linux, specifically LUBUNTU 16.04.This is how I installed sigrok/PULSEVIEW:




Then, install the firmware for the USBee AX using these instructions:




Use sudo to copy the attached file 99SaleaeLogic.rules into /etc/udev/rules.d

Remember to add your username to the plugdev and dialout groups.

Now you have a very effective logic analyzer for about $12 !!!

Have fun...
