New Module Description and SDK Brief Introduction

1 SDK Important File Description​

1.1 Board Configuration​

File location: apps\earphone\board\br28\board_config.h In board_config.h, we select CONFIG_BOARD_JL7016G_HYBRID. This activates the following three basic configuration files:

  1. board_jl7016g_hybrid_cfg.h
  2. board_jl7016g_hybrid_global_build_cfg.h
  3. board_jl7016g_hybrid.c In board_jl7016g_hybrid_cfg.h, we can further configure pins for peripherals such as UART, IIC, SD, etc.

1.2 SDK Startup File​

File location: apps\earphone\app_main.c In app_main.c, we can see the SDK startup process. This file can be divided into two parts: task_info task_info_table[] and app_main()

  1. First is task_info task_info_table[], which is a task information table that defines the name, priority, core to run on, stack size, and heap size for each task. Each task corresponds to a specific functional module.

  1. Next is the app_main() function, which is the SDK entry function. It creates and starts various tasks according to the configuration in the task information table.
