TTGO T-Encoder 在几个月前就推出了,它内置有一个由 usb 供电的拨盘、配备 ESP32 微控制器,而且可以支持 WiFi 和蓝牙连接。现在,用户只要借助 T-Encoder 扩展板,就可以制作一个带拨盘功能的键盘。另外,该开发板还具有两个机械开关和带 RGB LED 背光的键帽。后续...
ESP32Encoder ESP32Encoder library that uses the ESP32 pulse counter hardware peripheral: https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/pcnt.html There is only one interrupt for the peripheral, and that is managed by the library. The user has no interrupt interf...
This ESP32 component uses a debouncing state machine to track the position of an incremental rotary encoder such as the EC11 or LPD3806. These encoders provide two outputs (typically "A" and "B") that have a quadrature relationship - that is, they oscillate between high and low as the sh...
I am trying to use the ESP32 RMT Perphial to generate a Pulse Code Modulation signal using the "new" copy encoder. The copy encoder is failing with RMT_ENCODING_MEM_FULL. In the example below I generate the RMT_ITEMS from HEX values. The RMT_ITEMS appear correct, but the copy encoder...
ESP32Encoder是一个用于ESP32微控制器的开源库,它利用ESP32内置的脉冲计数器(PCNT)硬件外设来读取旋转编码器的信号。与软件轮询方式相比,该库利用硬件中断处理,极大地降低了CPU负载,提高了读取精度和效率,特别适合需要实时处理旋转编码器数据的应用场景。
RotaryEncoderPCNT This is a 2-channel rotary (quadrature) encoder implementation, for the ESP32, on the Arduino platform. It uses the ESP32's built in pulse counter (PCNT) peripheral. The PCNT unit is set up to keep the encoder object updated in the background, handling interrupts, intern...
The MT6701 library provides a simple and effective way to interface with the MT6701 magnetic rotary encoder using ESP32. It supports reading angular positions in radians and degrees, calculating rotational velocity in RPM, and smoothing RPM values with a moving average filter. The sensor uses I2C...
