9、esp32上实现本地 TCP 客户端和服务端角色,可断线重连原路返回数据。 10、乐鑫esp32 SDK编程利用rmt驱动ws2812七彩灯,实现彩虹渐变效果。 11、入门 乐鑫esp-adf 音频框架开发,esp32造一个蓝牙耳机,实现切换歌曲,获取歌曲信息等功能。 12、开源一个微信公众号airkiss配网esp32以及局域网发现功能的工程,分享一个a...
WTN6040这款IC支持多种通信方式, 具体可参考手册, 但ESP32引脚数量有限, 于是选择一线串口通信就足够了, 原理上和WS2812灯珠的驱动方式一样, 放一个时序图, /** * @file wtn6040.c * @brief wtn6040 driver * @author William * @date 2022.5.10 * @version v0.1 */ #include "wtn6040.h" #define ...

NeoPixel (WS2812) Driver Example code using RMT peripheral This project contains example code for driving a chain of NeoPixels connected to an ESP32 using the RMT peripheral build into the micro. This code assumes you are using FreeRTOS. Pros It's very simple to use! The code utilizes hard...
Advanced users can enable both the RMT5 and SPI drivers if they are willing to manually construct the SPI driver and it to the FastLED RMT5 driver has been fixed for ESP32-S3. Upto 4 RMT workers may work in parallel. Rebased espressifs led_strip to v3.0.0 ...

Currently i am trying to control WS2812 LEDs with ESP8684. But i got information that all libraries available for ESP32 are based on RMT or I2S while ESP8684 do not have either RMT of I2S . Is there any other library or method to control WS2812 using ESP8684 (ESP32-C2) ? No ...
Combine these with the ESP32 technical reference and the light bulb (figuratively and now literally has come on). I am delighted to report that I used the RMT driver library from C to control timings. By my calculation, the maximum possible resolution is 12.5 nano seconds. For our Neo...
