You can knock off the long time it takes to read a pin state when using gpio_get_level(GPIO_NUM_27).

Try using this instead.
#define INPUT1_PIN GPIO_NUM_27
#define INPUT1_PIN_READ() (REG_READ(GPIO_IN1_REG) >> (INPUT1_PIN - 32))


if ((uint8_t)INPUT1_PIN_READ() )
{}

Not sure if this is it or not. The examples show: ret = i2c_master_cmd_begin(i2c_num, cmd, 1000 / portTICK_RATE_MS);

Not sure if pdMS_TO_TICKS(10) results are the same as 10 / portTICK_RATE_MS

PIN_FUNC_SELECT(GPIO_PIN_MUX_REG[PIN_LED_RELAY2], PIN_FUNC_GPIO); gpio_set_direction(PIN_LED_RELAY2, GPIO_MODE_OUTPUT); gpio_set_level(PIN_LED_RELAY3, 1); Did you have a type here? Shouldn't it be PIN_LED_RELAY2 ? gpio_set_level(PIN_LED_RELAY3, 1); try... gpio_reset_pin(PIN_LED_RELAY2); gpio_set_di...

you dont need a " import" just manually copy the the files to your projects "src" folder

without .vscode folder, it is Eclipse project? if the person copied the entire project folder, then yes. Can I use VSCode to import those source code from Eclipse project to VScode project? all you need to do is create a new project in either IDE. Download the GIT .c / .h source files, and copy the...

if its a vscode project there will be a .vscode folder.

How about trying gpio_reset_pin(GPIO_NUM_X); on the pins you want to reset before calling ESP.restart()

You can use ESP-IDF in Arduino

Instead of messing with loops and delays for controlling a servo. You should use ledc or the MCPWM feature. Are you aware that Espressif has an example for controlling a servo? https://github.com/espressif/esp-idf/tree/release/v4.4/examples/peripherals/mcpwm/mcpwm_servo_control#mcpwm-rc-servo-contro...
