名词扫盲 IO_MUX:即为IO的数据选择器,在多路数据传送过程中,能够根据需要将其中任意一路选出来的电路,作用主要是用于信号的切换。 GPIO matrix:即为 GPIO 交换矩阵,是外设输入和输出信号和 pad 之间的全交换矩阵。 概述 ESP32 芯片有 34 个物理 GPIO pad。每个 pad 都可用作一个通用 IO,或连接一个内部的外设...
I'm new in ESP32 programming. Reading di esp_idf documentation is seems that through IO_MUX and/or GPIO MATRIX most of the peripheals available can be assigned to any GPIO pin, but I cannot understand how to do that. Should I write a specific inizialization funtion for the pin assigmen...
Re: Clarification re. GPIO matrix and IO Mux PostbyESP_igrr»Tue May 23, 2017 2:49 am For example, JTAG, SD HOST, SDIO SLAVE, EMAC can not be remapped to other pins using the GPIO matrix (except for a few signals in SD HOST and EMAC). SPI, I2S and all the low speed periph...
