As a thought experiment.. Could you use an op-amp / differential amplifier - then adjust the output sine wave (using something like the AD9833 (see https://flowcode.co.uk/forums/viewtopic.php?p=11838#p11838) - and then adjust the frequency and start phase until the difference between input and outpu...

Might be - and just using the standard UART?

I just changed the target with idf.py set-target esp32c3 and uploaded - and away it went (I got a handful of C3 boards from Temu - also ideal for a current project)
In the 'preamble' sent by the chip -

USB mode USB-Serial/JTAG

Did you get the S3 to work? Just tested with a C3 and using the JTAG / USB link and printf("string"); works well with this variant too! So you could output to USB and 'catch' the data in App Developer here too? Note that you can use printf with optional arguments for example printf("V...

Try without the period ('.') - in the folder name.

This might be giving Windows / Make an issue?

Sounds all good - glad someone else has it up and running - not just me :-) I didn't install Python or GIT as I was upgrading - I've found installing both first (latest versions) also works well... I've not had too many issues using 5.5 - though some warnings about deprecated components (timer / RMT...

Thanks - i think folk are still having issues -although following the wiki instructions should be good

I posted a bubble sort many moons ago (https://www.flowcode.co.uk/mmforums/viewtopic.php?p=88632&hilit=sort+speed+arduino#p88632) - this sorted 'ints' but would be easy to change to floats I've also posted a quicksort - though it is probably overkill for 14 numbers (https://www.flowcode.co.uk/mm...

Will take a look.....

Testing again - using UART channel 1 (and default pins!) - I get Hello World output to USB - this still from printf(); - nothing from SendString()

There are a couple of (extra) blank lines between them - but otherwise - running okay (rather than 'crashing' as before)
