Re: Global constant is not accessible inside the F11 WLAN_ESP32 ConnectToSSID component macro.

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...

Re: Compiler Error - ESP M5Stack Dial

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)?

Re: QRCODE reader / Generator lib

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...

Re: Esp32 QRCode generation and decode

... 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...

Esp32 QRCode generation and decode

So QR code (Quick Response code) - were mentioned - and I thought I'd experiment with the esp32 components for this... First up. Generation - note that Flowcode includes a DrawQRCode component - and this will display a code on a display. However - to test decoding, to allow use in a web page from an...

Re: QRCODE reader / Generator lib

For the esp32 - there are components for the quirc and qrcode libraries which will decode / encode and should be fairly easy to incorporate into an esp32 project...
A lot of 'scanners' rather than using a camera output a string, certainly for barcodes (and maybe qrcodes?).

Re: Implementing a non blocking delay

My code has a 'count' of interrupts for on (set in main) and then to turn off (set in the ISR) - I used arbitrary times (a count of 10) - to allow simulation. ie: Pin HIGH - starts timing (sets count to '10') (note ISR runs continually) The time should be as required. ISR counts down - the ISR toggl...

Re: Implementing a non blocking delay

What did you try - my code as is, or something changed?

If we can get it to work for one input/output - the other two are just a cut and paste operation (and two new variables per LED)

Re: Implementing a non blocking delay

The input should just be A4 - not sure I saved it with this?

Re: Implementing a non blocking delay

Very quick change to no components - use View->Digital pins and change A4 to 1 to start the timer - B5 will change to 1 after delay then revert to 0....

As mentioned above - it would be better to make the pins properties.. But no timer before work :-(
