I am migrating an application from ESP32 to the ESP32S3. The application stores a few bytes in non-volatile storage but the nvs is not working when change platform to the ESP32S3.

The problem I am experiencing also occurs in the nvs example app, nvs_rw_value, which is simply storing a restart ...

We have an ESP32 application with a SPI interface to an FPGA. It's a simple 1-bit mode, half-duplex, CPU controlled Master using VSPI. It has to be fast so it's implemented using direct register control with a single core dedicated to the task. It works great!

It's part of a large application that ...

Acuario, ESP_Sprite, thank you for input. You are right. It was going into boot loader mode.

As suggested, I separated the power from the serial so that I could monitor the serial on power up, and every time it didn't start it was because it was going into boot loader mode.

I put a scope on the 3 ...

Hi All,

We have a project using the new ESP32-S3FH4R2 on our own board. It's a challenging design but the ESP32-S3 is really performing well and beyond expectations.

We have found a power up issue which appears to be specific to this device and are interested in whether it's a known issue or if ...

I need to write and read binary files on the SD card
Text files are no problem. They open with:
FILE *file = fopen(file_name, "w");
But the normal "rb", "rb+", "wb", " wb+" for binary files don't appear to be supported. I get file open errors.
Is there another library I should be using? How do you ...

Implemented successfully as above without issues. Thanks for your help.

Thanks. So does this look like a simple server? Do I just need a basic client ap that, after initializing the Ethernet (as in a basic example app), creates a socket (SOCK_STREAM?), connect(), and read with recvfrom(). It appears as if the data comes in when the motor is running so I don't need to ...

Thanks for your response.

As part of a large ESP32 project we need to receive data from an Ethernet connection on a legacy motor controller. We don't know much about the implementation in the controller itself except that the user instructions for manually collecting the data are: In PUTTY under ...

I need to read raw mode data through an Ethernet connection. It says in the ESP-IDF programming Guide that the lwIP Raw API is designed for single threaded devices and is not supported in ESP-IDF. Is it possible to read raw mode data with the ESP32? If so, what's the best way to do this. I'm using ...

You got it. Fantastic! It appears that v3.0 initializes with SPI's enabled. v4.2 initializes with SPI's disabled. All it took was:

DPORT_SET_PERI_REG_MASK (DPORT_PERIP_CLK_EN_REG, 0x00010000); // Enable VSPI Clock thru' DPORT
DPORT_CLEAR_PERI_REG_MASK (DPORT_PERIP_RST_EN_REG, 0x00010000 ...
