Macro Definition Documentation

◆ ICARUS_DATA_WORDS

#define ICARUS_DATA_WORDS 512

Data region size per task in 32-bit words.

Note: 512 words = 2KB per task Must be even for 8-byte alignment (ARM ABI requirement)

Definition at line 91 of file config.h.

◆ ICARUS_MAX_MESSAGE_BYTES

#define ICARUS_MAX_MESSAGE_BYTES 512

Maximum bytes per message pipe buffer.

Note: Widened to 512 to support Software Bus and CFDP PDU routing. Each pipe uses this as the static buffer size regardless of the capacity set at pipe_init() time.

Definition at line 76 of file config.h.

◆ ICARUS_MAX_MESSAGE_QUEUES

#define ICARUS_MAX_MESSAGE_QUEUES 64

Maximum number of message queues (pipes)

Note: Each pipe uses ~140 bytes in DTCM 64 pipes = ~9KB DTCM usage

Definition at line 68 of file config.h.

◆ ICARUS_MAX_SEMAPHORES

#define ICARUS_MAX_SEMAPHORES 64

Maximum number of semaphores.

Note: Each semaphore uses 16 bytes in DTCM 64 semaphores = 1KB DTCM usage

Definition at line 61 of file config.h.

◆ ICARUS_MAX_TASK_NAME_LEN

#define ICARUS_MAX_TASK_NAME_LEN 32

Maximum length of task name string (including null terminator)

Definition at line 102 of file config.h.

◆ ICARUS_MAX_TASKS

#define ICARUS_MAX_TASKS 128

Maximum number of concurrent tasks.

Note: Each task requires STACK_WORDS * 4 bytes of stack memory With MAX_TASKS=128 and STACK_WORDS=512: 256KB stack pool

See also: STM32H750 has 512KB RAM_D1 available for stacks

Definition at line 54 of file config.h.

◆ ICARUS_STACK_WORDS

#define ICARUS_STACK_WORDS 512

Stack size per task in 32-bit words.

Note: 256 words = 1KB per task 512 words = 2KB per task (increased for printf with floats) Must be even for 8-byte alignment (ARM ABI requirement)

Definition at line 84 of file config.h.

◆ ICARUS_TICKS_PER_TASK

#define ICARUS_TICKS_PER_TASK 50

Number of SysTick interrupts per task time slice.

Note: At 1ms SysTick, 50 = 50ms time slice

Definition at line 97 of file config.h.
