esp32 小车控制 物联网 嵌入式 wifi arduino MCU驱动ESP32 AT程序 esp32 mcpwm 简介ESP-IDF版本:V5.1.2ESP32的MCPWM外设是一个多功能的PWM生成器,集成多个子模块,在电力电子应用(如电机控制、数字电源等)中至关重要。常用于电极控制,H桥转换电路等。如图,是MCPWM外设的主要子模块 ESP32编程指南中图片 ESP32...
ESP32 supports two MCPWM units. These MCPWM units can be used to control motors directly. Each MCPWM has three pairs of outputs mentioned below. you just need to configure these registers with any GPIO pins. you can find more information about these registers in the datasheet. Registers names...

Use theLEDC, or the MCPWM, or maybe even the RMT peripheral if you have to, but please, for everything that's holy to you, don't try to create that PWM signal in software on an ESP32. There are too many things (interrupts, multi-tasking,...) going on in the background for you...
Breaks the ethernet. So this is not firmware or software stuff. I just configure the GPIO matrix registers. Configuring these bits the MCPWM signal appears at the output however the ethernet is broken (as it is in my example). The values of these bits: ...

sizeof(adc_oneshot_unit_ctx_t):每个元素的大小。这里,我们使用sizeof操作符来获取adc_oneshot_unit_ctx_t类型数据的大小(以字节为单位),然后把它作为calloc函数的第二个参数。这意味着我们想要分配一块能够存储一个adc_oneshot_unit_ctx_t类型数据的内存。
