Re: Good looking display

I must say that Eink is not that expensive, provided the benefits it gives: Very low energy consumption Are able to refresh up to 1000000 times (at least) Stores the last print, which is ideal to cope with a low consumption ESP32 using deepsleep ( 0.08 mA / hr ) In this page I made a comprehensive l...

CALE is a new project with ESP32 in mind: To make a simple Eink Firmware that refreshes with fresh content from the web

Hello dear ESP32 community members, Since 2 months, especially latest weeks, since right now Europe is the main focus of this COVID19 I've concentrated building this web service that started with this Firmware in Hackaday My idea is basically to provide a service that is free for personal use and al...

Re: How to get miniz working.

There is an example on the IDF : https://github.com/espressif/esp-idf/blob/master/components/esp32/test/test_miniz.c Now keep in mind that #include "esp32/rom/miniz.h" includes only the low level deflate / inflate methods. I'm sending compressed data ( led matrix video ) from an Android app and I fo...

ESP32-S2 not working with SPIFFs example

I'm trying to make a very simple and straight-forward ESP32 benchmarking tool: https://github.com/martinberlin/ESP32-benchmark/tree/develop And when I tried adding the ESP-IDF documented Spiffs example, it works great on ESP32, but when I delete build directory and change target: idf.py -D IDF_TARGE...

ESP32 IDF Benchmark

I'm starting very slowly, since is hard to find time, a ESP32 Benchmark code for IDF https://github.com/martinberlin/ESP32-benchmark I will love to receive ideas, for example, to do interesting benchmarks that can also be compiled and uploaded in the coming soon ESP32S2 board with one LX7 Core. So f...

Re: Problema al compilar

I think that maybe you are selecting the wrong board in Arduino. I highly recommend switching to PlatformIO IDE to compile things for the ESP32 https://platformio.org/install This will make things easier and it's nice since keeps libraries for your Project inside a folder in the project itself. The ...

Re: Dimming Neopixels, Delays<Microseconds

Totally agree with ESP_Sprite.

Note that if you are using Neopixels Makuna library there is a I2S bug that is sometimes not refreshing the leds correctly. Use the RMT methods for the ESP32. Then you can have as much as 8 channels and control a lot of pixels.

Re: ESP32 control via UDP datagrams

Very nice example. We also use UDP for some of our LED projects. The only limitation is that at least in Arduino framework, you can only receive until 1,47 Kb that is more or less the Maximum Transport Unit (MTU) in the ESP32. More than that and you should use a buffering function. And that at least...

Re: ESP32-S2 toolchain installed. Works, suggestions to make it clearer for the user of existing IDF

Nicht Böse gemeint! Sure actually I want to do a full ESP32 test but that compiles on ESP-IDF, so nothing Arduino Framework, strictly ESP-IDF documentation and code examples. And it's no problem I will compile anything you want provided it compiles with IDF and share with you all results. Arithmetic...

Re: ESP32-S2 toolchain installed. Works, suggestions to make it clearer for the user of existing IDF

This is the version : xtensa-esp32s2-elf-gcc (crosstool-NG esp32s2-dev-4-g3a626e9) 8.2.0 What I really don't understand is why the version is relevant for you and in the second why in this ESP32 post where I was trying to make another point? If you want to help, clone this, and let's pass it with mo...
