As with os_dbg.c, os_cfg_app.c defines a number of ROM variables. These variables, however, reflect the run-time configuration of an application. Specifically, the user will be able to know the RAM footprint (in bytes) of µC/OS-III task stacks, the message pool, and more.
Below is a list of ROM variables provided in os_app_cfg.c, along with their descriptions. These variables represent approximately 100 bytes of code space.
Application code can examine these variables and the application does not need to access them in a critical region since they reside in code space and are therefore not changeable.
| ROM Variable | Data Type | Value |
|---|---|---|
OSCfg_IdleTaskStkSizeRAM | CPU_INT32U | sizeof(OSCfg_IdleTaskStk) |
This variable indicates the RAM footprint (in bytes) of the µC/OS-III idle task stack.
| ROM Variable | Data Type | Value |
|---|---|---|
OSCfg_ISRStkSizeRAM | CPU_INT32U | sizeof(OSCfg_ISRStk) |
This variable indicates the RAM footprint (in bytes) of the dedicated Interrupt Service Routine (ISR) stack.
| ROM Variable | Data Type | Value |
|---|---|---|
OSCfg_MsgPoolSizeRAM | CPU_INT32U | sizeof(OSCfg_MsgPool) |
This variable indicates the RAM footprint (in bytes) of the message pool.
| ROM Variable | Data Type | Value |
|---|---|---|
OSCfg_StatTaskStkSizeRAM | CPU_INT32U | sizeof(OSCfg_StatTaskStk) |
This variable indicates the RAM footprint (in bytes) of the µC/OS-III statistic task stack.
| ROM Variable | Data Type | Value |
|---|---|---|
OSCfg_TickTaskStkSizeRAM | CPU_INT32U | sizeof(OSCfg_TickTaskStk) |
This variable indicates the RAM footprint (in bytes) of the µC/OS-III tick task stack.
| ROM Variable | Data Type | Value |
|---|---|---|
OSCfg_DataSizeRAM | CPU_INT32U | Total of all configuration RAM |
This variable indicates the RAM footprint (in bytes) of all of the configuration variables declared in os_cfg_app.c.
