Hi all, Thanks for the info on the ADE-25MH's and ESP32. Wondering about the potential to run more than one task on both cores like in ESP32 on steroids using two cores

Dave You just missed post #828, Joerg has the solution. In the tinySA.ino file change the line: BUFFERSIZE 512 to BUFFERSIZE 32 You have the same problem I had.? The fix WORKS. 73, Gary WB6OGD

With some poking around on the web, it appears that the serial read buffer is 64 bytes. So Serial.readStringUntil() might be suitable for grabbing a newline terminated tinySA command from the host.

There's a lot left unsaid in the Arduino documentation. For example, from https://www.arduino.cc/reference/en/language/functions/communication/serial/readstring/ " Serial.readString() reads characters

Hi Group. I also had not realised the Logger window had to be open. With the logger window open I can reduce the speed down to 0 and it works for a single scan.? With the logger window closed it

YES. How do you get away with it with your 32bit Zero?? It does it all in hardware and is fast enough? 73, Gary WB6OGD

The problem is in the USB serial driver. If you give a large buffer to send it crashes. With the Arduino monitor you get very small transfer. -- HBTE Files section: /g/HBTE/files

I have one modified module to show. Will take some pictures and use example schematics (there are many different filter configurations being used). Will take some time W.r.t to boxing up. YES. In

Dan, I am just like you.. wanting to be a real RF engineer but have a long way to go. Every project I build I get more of an education than I even expected.. they never work the first time ;-) I say

Joerg, NO, I missed that..? well I remembered something about reducing it, I know I tried 64 without any change.. BUT.. 32 WORKS!!!! You are good!? THANK YOU VERY MUCH! I will have to try to

Erik, I don't consider myself to be anything close to an RF engineer but VNA's and SA's have fascinated me for years. I think I'm going to give it a try making up your tinySA project. I was wondering

Gary, did you reduce BUFFERSIZE to 32 in the Nano C-code as I mentioned in message #721? With this change communication with the SA.EXE and the Nano worked fine for me. I can run 3000 points without

Here is from the Nano: <<x54 <<x49 <<x49 <<x57 <<x51 <<x54 <<x52 <<x53 <<x76 <<x52 <<x54 <<x51 <<x53 <<x54 <<x52 <<x61 <<x57 <<x81 <<x111 <<x96 <<x229 <<{ <<Steps: 100_ <<time pr step: 90_ <<Stop:

Erik, We are getting somewhere! I did not know you have to open the log window before doing a sweep. When I do, I see the Nano IS sending back good data.. only problem is it stops at about 10 (doing

Test option: When you start sa.exe and activate file/connect... , do you also see "Mockup"? Click on mockup and OK Then view/view log Log window opens with "empty" Then click "RUN" and see if the log

I use the same sweeper core code also on a nano using a somewhat different windows executable (TAPR-VNA) No issues. Extremely weird -- HBTE Files section: /g/HBTE/files Erik, PD0EK

The log window will only be populated when activated so you first have to open the log window and then do a sweep -- HBTE Files section: /g/HBTE/files Erik, PD0EK

That makes sense. I only ask because pretty much all SA plots I see in the forums seem to be linear. Can't recall ever seeing a log plot from an SA. Jerry

Thanks Erik, Unfortunately new version gives same results for me. One think I have noticed is when I unplug/plug the USB cable, then open tinySA.exe I get a pop up error window that says "no sweeper

Certain measurements are best done in log sweep but acceptable if not available as with more points you can display In log scale -- HBTE Files section: /g/HBTE/files Erik, PD0EK
