Marty, email me and I'll send the zip files for the libraries. -- John P. WA2FZW

John / Dave, Thanks very much for the latest V1.3 file. Trying to compile the sketch and finding that I need to add several header files to make the compile work (I've tried adding them and then get

Sorry Erik, this is time per point, not the whole sweep.? Apologies for not being accurate.? So for the 290 points (if Auto RBW and wide bandwidth) around? 210mS for the full sweep. Dave

What is meant with "Sweep time"? Total time for one full sweep? Time for one point? -- HBTE Files section: /g/HBTE/files Erik, PD0EK

Actually, you can use the parallel attenuator without the PCF8574 GPIO expander but you'll need to?repurpose some of the GPIO pins we've reserved for future enhancements. They are listed in the post

Hi Glenn.? Well done! Interested to see your sweep time is much slower than the 720uS or so I see with no WiFi clients, around 780uS with a WiFi client.? Are you running the display at 40MHz? 73

Hello, This email message is a notification to let you know that the following files have been uploaded to the Files area of the [email protected] group. * /Tiny Spectrum Analyzer/ESP32/tinySA_V1.3.zip (

Got mine up and running after dinner tonight. Using the PCB shown in another thread. Using Sketch by Dave and John at moment on ESP32 Wrover. Early days to see just well it performs. Glenn vk3pe

Marty et al, here are the pin assignments for the ESP-32: GPIO-0???????????????? SD_CS????????????? Reserved for SD card chip select GPIO-2????????????????

Dave / John, First off, as we're in these unprecedented times with this viscous flu (I refuse to give it credit of a name being the scourge on mankind that it is) I hope and pray that you're healthy

David's next release will include support for the VK3PE Version 1 PCB set which uses a PCF8574 GPIO expander between the processor and the attenuator (saves a few GPIO pins for future enhancements). I

Hi Marty, I hope you and everyone else reading this group are safe and well. I am also working remotely, and so far is working out OK. The Version 5 release was a bit flakey on the touch sensing, and

Dave, Apologies if this message is requesting repeat info but I've been working from remote for the past two weeks (and for the foreseeable future until this COVID-19 threat is behind us) and I'm JUST

While somewhat on the topic... any issues with your latest mod for adjusting to a relative value??http://kv4qb.blogspot.com/2020/01/small-update-t-step-attenuator.html

I am planning on using the simple parallel versiono of the attenuator board.? I have used these in a 63 dB. varfiable attnuator project http://kv4qb.blogspot.com/2019/04/63-db-step-attenuator.html

Yeah! Glenn is making me bite the bullet and learn how to handle things I can't even see! I have the magnifying glasses, one of those digital microscopes tons of tweezers and dental picks. My dentist

True… but in this day and age… with parts getting smaller and smaller, you gotta work to get over that…. I’ve invested in a lot of equipment just to manage small parts. Stereo scopes, several

Another reason for using the *parallel board* is the perceived difficulty by some, in soldering small smd IC's.? Yes for some its a challenge, no doubt. My board for example,? is mostly smd parts as
