Re: Not Displaying the Frequency....
It appears that some of Jerry¡¯s nearly daily posts relate to self inflicted issues. I think he is a veteran and talented bit banger so his posts always lead this old (nearly 83) system engineer to

Re: Not Displaying the Frequency....
You're right. Tell you what: I work on being less defensive if you are more thoughtful in your word selection when criticizing the T41 Project. The T41 is not my project. It is the distillation of the

Re: Not Displaying the Frequency....
Not the project, just the tuning. It works great once you get where you're going. It's quite an achievement, Jack. You deserve kudos for bringing it to us. Don't be so defensive. - Jerry, KF6VB

Re: Not Displaying the Frequency....
Working toward minimal audio disruption from display changes will make the tuning useable - but still not nice Why would I not get that impression? To imply something is "unusable" clearly implies

It already has a WIFI block onboard and an minipci bus too. Amazing little board. The documentation says Verilog is the right tool for programming. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ

Thanks for the update. Yep. I¡¯m very familiar with the Radioberry. I have a couple of them and they work flawlessly. Using the Radioberry and the Hermes projects as examples, I¡¯m convinced that

Re: Not Displaying the Frequency....
*** Yet it is very disruptive to the audio. Why is that? I think it's because interrupts are disabled during SPI transfers. Tracking what has changed and what hasn't changed would likely ***

Toroid Winding
All: I'm winding the toroids for a new LPF board. Because the filter might be used with Bill's 100W PA, the wire size is increased to #20 gauge for winding on T68 cores. Because of the thicker wire

Re: Not Displaying the Frequency....
Stripping functionality was just done as a test. As a solution - doing video in small chunks is just as functional as doing it all at once. And - you gotta get the basics right. THEN you add all the

Re: Not Displaying the Frequency....
Things are a little improved. There is a call to tft.fillRect() that erases the area where the frequency is displayed. Theorizing that audio interrupts are held back while that's done, I split it up

Re: Not Displaying the Frequency....
I suspect I understand...and it's not good. I think that SPI requires precise timing, and audio interrupts are disabled during long video transfers. Yet... the audio works fine while the spectrum, the
