Simple Console Initializer

The component provides a simple api's to initialize and start the esp console. It also provides an api to register an user provided command.

API

Steps to enable console in an example code:

1. Add this component to your project using idf.py add-dependency command.
2. In the main file of the example, add the following line:

   #include "console_simple_init.h"

3. Ensure NVS flash is initialized and default event loop is created in your app_main():

   ESP_ERROR_CHECK(esp_event_loop_create_default());
   esp_err_t ret = nvs_flash_init();   //Initialize NVS
   if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
       ESP_ERROR_CHECK(nvs_flash_erase());
       ret = nvs_flash_init();
   }
   ESP_ERROR_CHECK(ret);

4. In your app_main() function, add the following line as the last line:

   ESP_ERROR_CHECK(console_cmd_init());     // Initialize console
   
   // Define the function prototype for do_user_cmd
   // It's a function that takes an integer (argc) and a pointer to a pointer to char (argv)
   int do_user_cmd(int argc, char **argv);
   
   // Register the do_user_cmd function as a command callback function for "user" command
   // This allows you to execute the do_user_cmd function when the "user" command is invoked
   ESP_ERROR_CHECK(console_cmd_user_register("user", do_user_cmd));
   
   
   ESP_ERROR_CHECK(console_cmd_start());    // Start console
