I guess I work in a bit of a strange way, and I like to know exactly what is going on in code, so I am not a big fan of "black box" systems and libraries. I realise now just how good Atmel data sheets were!

The EPS32 data sheet are OK, but for example with the ADC... the register information is ...

I'm just old fashioned I guess! Most of my experience is from programing Atmel microcontrollers, and I find all the ESP32 APIs so very abstracted and exceptionally challenging to know what they are doing and how to use them!

I am trying to set up a transparent ethernet bridge.
I found some code "eth2wlan" online, which is an adaptation of the example code eth2AP, which has the ability to switch to STA instead.

The code works fine in either STA or AP mode if I use just one esp32-s3 module with W5500 ethenet IC. I get a ...

Did you manage to get anything working?
I am trying to do a similar project. I found some "eth2wlan" which sort of does the job, but it seems to loose 93% of the data, so I am really struggling!

I have been trying to do a similar thing myself. You could try using the eth2wlan example for the STA side, though I am finding a great problem with lost data packets. Perhaps you are experiencing this too?
I have 2 computers set up on the ethernet bridge, and using iperf. testing the data ...

I have been setting up the RMT to measure pulse widths of an incoming pulse train using direct register programming, and have been getting nowhere for some time.
I have been using the FIFO for automatically storing and reading out the Data, but the data has be total nonsense, even with consecutive ...

So with some help from ChatGpt and much MUCH.. digging and reverse engineering of the header files, what seems to happen is when you use some of the ADC APIs, the code actually pulls out a table of "Attenuation values" from the EFuses on the ESP32, at boot up.

When you then call the API to do an ...

Did you enable and un-clockgate the MCPWM peripheral? (periph_ll_enable_clk_clear_rst)


Hi ESP_Sprite Many thanks! I checked and saw I made the foolish mistake of SETTING the clock reset, and not clearing it!

In case someone one day wants to do similar here is the code:

#include <stdio.h ...

I am trying to better understand the basics of the ESP32-S3 registers.
I wish to run a simple test ADC conversion on GPIO pin 2. But am unable to get the ADC running.
I can use the APIs:

adc1_config_width(ADC_WIDTH_BIT_12);
adc1_config_channel_atten(ADC1_CHANNEL_1,ADC_ATTEN_DB_0);
val = adc1_get ...

I am trying to set up the MCPWM on a esp32-3s wroom-1 module.

I want to write to the registers directly to set the PWM up, but none of the values are changing after I write to them for example:

WRITE_PERI_REG(MCPWM_CLK_REG(0) , MCPWM_CLK_EN);
WRITE_PERI_REG(MCPWM_TIMER0_CFG0_REG(0), ((0x0<<MCPWM ...
