I continue to try (unsuccessfully) to connect an rmt output to a gpio AND to a pcnt input. I am still confused by Chapter 4 of the TRM even though some have tried to explain it to me. It would help if I could find the c code for gpio_matrix_in and gpio_matrix_out. I have ...
gpio_matrix_out(PIN_SMI_MDIO, EMAC_MDO_O_IDX,0,0);gpio_matrix_in(PIN_SMI_MDIO, EMAC_MDI_I_IDX,0); set the Direction BIT of the GPIO in this example MDIO is in and output https://esp32.com/viewtopic.php?f=12&p=6422#p6401 ...

在esp32s2.rom.ld中能够看到,gpio相关的操作函数也都封装了进去,看来乐鑫隐藏了一些寄存器的额细节。让用户更多的关心应用程序的编写。 PROVIDE ( gpio_input_get = 0x400193a0 ); PROVIDE ( gpio_input_get_high = 0x400193b4 ); PROVIDE ( gpio_matrix_in = 0x40019430 ); ...
gpio_set_direction(config->pin_pclk, GPIO_MODE_INPUT); gpio_set_pull_mode(config->pin_pclk, GPIO_FLOATING); gpio_matrix_in(config->pin_pclk, CAM_PCLK_IDX, false);你么能不能告诉我这几个函数文档为什么没有?浪费时间送TA礼物 1楼2022-08-19 01:07回复 ...

(黑色虚线框指的是GPIO矩阵 (GPIO Matrix)) **1、操作器模块 Operator** **操作员 (Operator) 用于操作连接到MCPWM单元的电机。**例如改变旋转方向(顺时针或逆时针),或改变转速。 ? 操作员输出一共有 3 对,我们可以对其施加控制信号。标记为“A”和“B”的称为一对。A、B均有自己对应的名为“Generator”...
硬件的 SPI 更快 (高达80Mhz),因为esp32的GPIO Matrix功能,你可以在任意的引脚绑定。 Native SPI pins: SPI id clk mosi miso HSPI 1 14 13 12 VSPI 2 18 23 19 Native pins 最大的 SPI 时钟可以到达 80 MHZ. 如果你使用了 gpio matrix 连接到其他的引脚, 最大 spi 时钟是 40 MHz(半双工),26 ...
