it's me again. I've now dealt with the structure rmt_item32_t very intensively and I don't think that analogues will be able to be read out directly with RMT functions. Am I correct?

ypedef struct {
union {
struct {
uint32_t duration0:15; /*!< duration of RMT carrier */
uint32_t level0:1 ...

I have now managed to use the RMT function to access data from my GPIO, but the output only shows 1,1,1,1,1,1.
Now how do I make it write the analog value 0 - 4096 of this GPIO to the buffer?

Here my code:
short explanation. A 1kHz signal is generated with GPIO 32 and read back on GPIO 35. Now the ...

Thanks for your answer.
MCPWM is not entirely out of the question.
But thanks for the tip with RMT. I still have absolutely no idea how to do this, but it seems promising.
The way I read it, it's something similar to generating a PWM, just the other way around for reading. at least you can use it ...

would be nice if someone could help me here! THX!

Thanks for the link but can I do something with it? These are roof instructions for ESP-IDF in a requesting environment than Arduino IDE?

That's good news... since it's not in the Arduino IDE library, I was afraid that this wasn't possible.
I would like to take 20 cyclic measurements of the input value from an ADC in 1 millisecond and then the values can be further processed by the user program.
The aim is to capture the high value of ...

Hy,
I'm trying to use DMA on my ESP32-WROOM-32U-N16 and I'm new to this topic.
1) Can the chip do that at all?... I can't find anything about it in the documentation.

I have the problem that the command mcpwm_isr_register does not execute the interrupt command.
