It's not specifically geared towards your specific flavor of the ESP32, but it would not matter much at all.

Can you post your code?

Re: Simple switch to turn on my fireplace with low voltage
Something does not sound correct there. Maybe its AC and your reading with a DC meter ?However, the actual manual switch on my fireplace runs with very little voltage. About 0.2v.
Best bet is to use a relay.

Re: Esp32-S3 with POE (w5500)?
You need to use a RJ45 that supports POE. I.E. it brings out the POE pins.
something like ARJM11D7-114-AB-EW2
For the POE power supply I have use the AG9903-MTB.

Re: ESP32-S3 boot mode
He brings up a good idea. I dont know if it could be implemented in menuconfig. It would be a nice feature to enable/disable those bootstrap pins.

Re: can't printf with ESP32-S2 ESP-IDF 5.1
FYI, printf works just fine in Arduino.As far as I know, printf will not work in Arduino frameworks. Rather it should be Serial.print()

Re: Espressif DSP Library help
FWIW, in the example this function " dsps_tone_gen_f32(x1, N, 1.0, 0.16, 0); "Seems pretty trivial to me: the functions take int16_t types
fills x1 with float values from -1.0 to 1.0. Why do you say it takes int16_t types ?

Re: Espressif DSP Library help
I apologize if that is how my statement came off. It's intention was just to explain I am under the gun on something I know very little about, and could use some help in a big way is all. You'r expiation was very helpful. Embarrassing obvious now that it was pointed out. If I take the fft example as...

Re: Espressif DSP Library help
I have thank you, but its not clear to me what is the min/max values my data needs to be to pass to the functions.
