I'm finding that the SPI TFT interface is easier to work with. When I get this book done, I have a couple of things I'd like to try with this guy. Jack, W8TEE

The communications on this rig suck - too many hands in the pie. Depends upon how you define communications. There are thousands of posts on the BITX site, which suggests very good communications. If

Ultimately this is a technical forum... "Ultimately", yes, but to preclude non-technical topics seems overly-restrictive. Increasing the number of US operators in the HF spectrum slice might be of int

Reed: I agree. I do think most techs would like to have SSB privileges on the HF bands, even though they haven't tried it. Our club gives the exams every month but Dec, and I recall running into one w

Dennis: You will really enjoy the hobby much more if you upgrade. I'll bet if you would spend 1 hour per night studying Ham Test Online (http://www.hamtestonline.com), you'd pass your General after tw

No, I don't. I understand the ease of use of the Nextion, but don't like the result. To me, a Nextion display looks "clunky", and I can't really put my finger on why. I was willing to pay the coding p

Arv: Thanks for the kind words. I've told the story before, but I always wanted to be a EE person from the time I got my Novice license at age 11! After the 8th grade, you had to choose a vocational o

OK...and on Arv's post, too. The EE stuff is over my head anyway! Jack, W8TEE

If the "meter" is actually a display, software can easily take care of the "jumpiness" using a non-blocking delay function. Jack, W8TEE

I was using the ESP32 and the TFT_eSPI graphics library. The code is shipped as one of the examples. The ESP32 is a bitch-kitty to completely understand, but it has a lot of resources to offer (e.g.,

#arduino #nextion

I thought tapping onto a volume control yields a Vu meter, not an S meter. I'm confused. Jack, W8TEE

#ubitxv6 #firmware

Yes. It will be out in September and the price will be $34.95. I asked if it will appear in the Sept or Oct issue of QST, but haven't got an answer yet. Jack, W8TEE

Dean: I just bought 10 480x320 touch screen TFT SPI displays for about $12 each. They are about $14 Q1. They use the ILI9488 driver which is supported by several graphics packages. I've been messing a

Hi Dean: Yep, the resource depth of the Nano just isn't there for what I want to do. Also, the 2K SRAM limit is the most constricting limitation, and use can't accurately be judged at compile time. My

Dean: I did work on the JackAl using a 5" touch screen and it works well, but used a Teensy 3.6 for the processor. The display I'm using now is a 2.8" TFT display (see:QCX CAT Demo) which supports a t

Some of the errors look to me like an #include file is missing. Check your library directory to make sure you have all of the header (*.h) files included. A lot of the errors are of the sketch/setup.c

You need to copy the error message list to a TXT file and post it, as that's about the only way to see what's going on. Also, what OS are you using and which version of the IDE and have you installed

#v6 #nano #ubitxv6

I think the Raduino is the name given to the display interface, which includes the Nano and the LCD display. If you are using software to upload to the Nano, Nano is the correct choice for the upload.
