default LOG_VERSION_1
help
Select the log version to be used by the ESP log component.
- "V1": This version integrates log formatting into the format string provided by the user.
Logs are processed and formatted during compile time, leading to a larger binary file.
Example: ESP_LOGI("boot", "chip revision: v%d.%d", major, minor);
Output: I (56) boot: chip revision: v3.0
Note: Log strings are stored in Flash with added formatting characters.
Format string on flash: "[0;32mI (%lu) %s: chip revision: v%d.%d [0m"
- "V2": This version centralizes log formatting within the esp_log() function.
User-supplied format strings are stored without added formatting, reducing binary size.
Example: ESP_LOGI("boot", "chip revision: v%d.%d", major, minor);
Output: I (56) boot: chip revision: v3.0
Note: This version supports runtime configuration of formatting and is more flexible,
logging from constrained environments (ex.: ISR, Startup, Cache disabled).
It may consumes a bit more stack and affect performance.
Format string on flash: "chip revision: v%d.%d"
Use V1 for minimal stack usage and simpler implementation.
Use V2 for smaller binary sizes, more flexible log formatting, and advanced features like disabling
colors or timestamps.

Select this option to use Log V1. Recommended for projects with strict stack constraints
or that prioritize performance over flexibility.

Select this option to use Log V2. Recommended for projects that require smaller binaries,
runtime log formatting configuration, or advanced logging features.

Enables support for color codes in the esp_log() function. If CONFIG_LOG_COLORS is enabled, this option
is always active. If CONFIG_LOG_COLORS is disabled, this option allows you to still handle color codes
