Allocating large memory areas without getting 'dram0_0_seg' overflowed

Hi, I have and ESP32 S3 with 520 K memory, and 340 free, but I cannot allocate a large memory area (like ~300), without getting a "dram0_0_seg' overflowed" error. I have tried both statically and dynamically. The .ld scripting seems very complex, to the degree I don't know where to begin to fix it. ...

Re: Building OpenCV for the ESP32 error

If it helps, I made a PR to joachimBurket/esp32-opencv to make it work on the ESP32-CAM, and fixed IDF 5.3.0 support:

VS Code extension 5.2.2 installation issues on Windows 11

Hi, I am having issues installing ESP-IDF using the "Configure ESP-IDF Extension". I have tried sort of all kinds of stuff but seems to always end up with: Installing Python packages Constraint file: C:\Espressif\espidf.constraints.v5.2.txt Requirement files: - C:\Users\Nickl\esp\v5.2.2\esp-idf\tool...

A bit like Spring/Jakarta/.NET/Django/React, but on top of ESP-IDF/Arduino/STM32 et al

..and not for serving web applications. But to make development faster. Hi all, First, I just I wanted a cheap way to make a redundant network for my boat, as I was tired of glitching cables, so i combined the ESP32s built-in wireless and wired for backup and that each could report on the others fai...

TWAI FD

Hi! TWAI would feel like a much more safe route forward if there was any indication that support for ISO11898-1 FD will be included in future versions of the ESP32. As this is drastically expands the envelope for the usage of these kinds of networks, it would make a big difference for their wired us...

Re: LilyGO T-SIM7000G does not work with esp_modem

I have an error when i try to build this project ( https://github.com/U03/esp_modem_test ): I solved it, at least for me, now it builds. I took a real deep-dive and found this in netif:s CMakeLists.txt: if(CONFIG_PPP_SUPPORT) list(APPEND srcs "lwip/esp_netif_lwip_ppp.c") endif() Apparently, Compone...

Re: LilyGO T-SIM7000G does not work with esp_modem

I have an error when i try to build this project ( https://github.com/U03/esp_modem_test ): Just wanted to say I have the same problem. For some reason the esp-modem component can't get to some of the esp_netif stuff. Going crazy. BTW; the project shown seem to manually add the "components" library...

is there anything ready to use for streaming data from uart?
Actually I am as well. Trying to run EspSoftwareSerial which needs stream.h, and there is nothing like that in ESP-IDF.

Re: How do I list clients/connections in NimBLE?

As per usual in these cases; I feel dumb as a post. First, I didn't get that the peripheral examples didn't populate a peer list. I had mashed the peripheral and central examples together into one and obscured that fact to myself. Next, I made some mistakes in the code and misunderstood the SLIST_ m...

How do I list clients/connections in NimBLE?

Hi everybody! New to this, and I need help. With hope to be able to give back at some point. Anyway. I have looked all over on how to try to list, and then iterate over, any active connections to my peripheral/BLE server. To no avail. The ble_store seems to be empty regardless of object type (while ...
