I have a problem concerning the writing of the pins. I want to put them to 1 to drive a Multiplexers (MUXO & MUXI in the code below) but when i try to control MUXI, i have the error code in the Serial terminal "E (X) gpio: gpio_set_level(226): GPIO output gpio_num error"...
E (2131) gpio: gpio_set_level(226): GPIO output gpio_num error E (3231) gpio: gpio_set_level(226): GPIO output gpio_num error gpio设置错误,仅输入引脚被设定为pwm输出后出现此情况 不存在串口或者开发板 boot引脚设置错误

一、GPIO常用函数 esp_err_t gpio_reset_pin(gpio_num_tgpio_num) 1. 将gpio 重置为默认状态(选择 gpio 功能、启用上拉并禁用输入和输出)。备注此功能还将此引脚的 IOMUX 配置为 GPIO 功能,并断开通过 GPIO 矩阵配置的任何其他外设输出。参数gpio_num – GPIO 编号。返回始终返回ESP_OK。
After all the testing I found one line if I comment that camera works. Here is that line #define GATE_CTRL_RELAY_PIN 16 gpio_set_direction(GATE_CTRL_RELAY_PIN, GPIO_MODE_OUTPUT); why setting gpio 16 as output breaks the code ? I think I have found the answer...
I've tried the below functions to try "force" an output: Code: Untitled.cpp Select all // Directly setting as an output gpio_pad_select_gpio(pins[i]); // Enabling as an input first, then setting as an output using the below methods: gpio_pad_input_enable(pins[i]); // Force se...
GPIO set direction. Configure GPIO direction,such as output_only,input_only,output_and_input Return ESP_OK Success ESP_ERR_INVALID_ARG GPIO error Parameters gpio_num: Configure GPIO pins number, it should be GPIO number. If you want to set direction of e.g. GPIO16, gpio_num should be ...
