在D:/myself/ESP32s3/lvgl/components/lvgl_esp32_drivers/lvgl_tft/esp_lcd_backlight.c文件的第58行，编译器遇到了一个错误，提示信息为“implicit declaration of function 'gpio_matrix_out'”，即隐式声明了函数'gpio_matrix_out'。编译器进一步询问是否是指的是'gpio_iomux_out'，并给出了警告“[-Werr...
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 ...

没错呀,PIN_FUNC_SELECT了PIN_FUNC_GPIO,这是告诉IO MUX,外设信号从GPIO Matrix中拿. gpio_matrix_out选择具体的外设信号走GPIO Matrixshuiyihang0981 Posts: 2 Joined: Thu Sep 23, 2021 3:04 am Re: S2芯片手册上关于交换矩阵使用的疑惑by shuiyihang0981 » Thu Sep 23, 2021 6:17 am 那请问,交换...
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: SPIidclkmosimiso HSPI1141312 VSPI2182319 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 MHz(全双工) 所以,大...
