### Print storage-related information (KV example output)

Source: https://github.com/stevenbobo23/tuya_open_doc_example/blob/main/examples/system/os_kv/README.md

Output from the KV example showing flash storage parameters such as start address, size, block/sector size, swap flash details, key restore address, protected address, and physical block size. Use this to verify the storage configuration of the KV database.

```c
[01-01 00:00:05 TUYA D][lr:0x4a767] start flash : 1ef000
[01-01 00:00:05 TUYA D][lr:0x4a76f] flash size : e000

### CMake configuration for MQTT client example

Source: https://github.com/stevenbobo23/tuya_open_doc_example/blob/main/examples/protocols/mqtt_client/CMakeLists.txt

Sets up the build for the MQTT client example. It defines the application path and name, collects source files from the src directory, and configures the target library with private include directories.

```cmake

# @brief 
#/

# APP_PATH
set(APP_PATH ${CMAKE_CURRENT_LIST_DIR})

# APP_NAME
get_filename_component(APP_NAME ${APP_PATH} NAME)

### Execution results of the software timer example

Source: https://github.com/stevenbobo23/tuya_open_doc_example/blob/main/examples/system/os_sw_timer/README.md

The output shows the timer starting, the callback '--- tal sw timer callback' being invoked 5 times at 3-second intervals, a watchdog feed, and finally the timer being stopped and deleted.

```c
[01-01 00:00:07 ty D][example_sw_timer.c:59] sw timer start
[01-01 00:00:10 ty N][example_sw_timer.c:43] --- tal sw timer callback

### CMakeLists.txt for Timer Example

Source: https://github.com/stevenbobo23/tuya_open_doc_example/blob/main/examples/peripherals/timer/CMakeLists.txt

Builds the timer example as a library when CONFIG_ENABLE_TIMER equals 'y'. Sets APP_PATH, APP_NAME, and APP_SRCS from the source directory, then creates a library target with those sources. Fails with a fatal error if the configuration is not enabled.

```cmake
##
# @file CMakeLists.txt
# @brief 
#/

if (CONFIG_ENABLE_TIMER STREQUAL "y")

# APP_PATH
set(APP_PATH ${CMAKE_CURRENT_LIST_DIR})

# APP_NAME

Expected console output after running the timer example. The timer starts, triggers its callback five times at one-second intervals, then stops and releases.

```c
