Yes - it does do that

Didn't know about the spectrum analyser - will have to check that out.

Never used the frequency generator either (it always seems a bit 'fiddly') - and if you get really fancy it's all open-source - so you can add the feature you need

Still comes highly recommended.

For a few days (till 2/2/26) the LabNation SmartScope is on offer at Elektor ( https://www.elektor.com/products/labnation-smartscope-usb-oscilloscope?_pos=1&_psq=smartsc&_ss=e&_v=1.0) for £67.15 (+VAT) I've used mine for many years (and it is always on the desk) - although it doesn't hav...

As it outputs the QR code text, QR version and ECC level - I used V for version - so it looks like

Greetings from Flowcode V5 - for a little nostalgia. I used v11 - but the encoder decided on a V5 QR code...

And to decode.... This just creates a QR code - and then decodes it using 'quirc' - I struggled initially to get the decoder to recognise any QR code (the image can contain multiple - just one here) - and the 'trick' was inverting the image - originally I created it as white (255) on black (0) - but...

That's very neat, thankyou. One suggestion - if you have a string as a parameter to a macro - untick the 'make local copy' check box - this saves duplicating the string (which takes time and memory) - and you can then pass strings of any size. So - you could have string msg_text[10000] as the parame...

I've also reported this - don't use global string constants here - connection will fail with the password as the two strings concatenated. Using a string constant (Connect("SSID", "Password") or string variables is okay though.. The string length FCsz_VAR doesn't include the term...

I'm not a a computer right now - but you can look at PulseGen v3a.c and look at the offending line - might give some clues (at least which macro the error is in)?

That looks like a interface board that needs a separate scanner. There do seem to be scanners with TTL output - see https://www.aliexpress.com/item/32865222900.html?src=google&pdp_npi=4%40dis!GBP!8.98!6.99!!!!!%40!12000046261271362!ppc!!!&src=google&albch=shopping&acnt=494-037-6276&a...

... and a first attempt at drawing a QR code - Here on an esp32s3 with and ili9488 (parallel) display. I had to make each 'pixel' a 5 x 5 rectangle - 1 x 1 is too tiny for my phone to read! It also ignores the x,y co-ords at the moment and always draws the code at 0,0. However - it successfully demo...
