8. Legacy Trice Space Example (Old Version)
9. Memory Needs for Old Example 1
10. Memory Needs for Old Example 2

Depending on your target configuration the needed space can differ:

1. F030_bare Size

./build.sh:

arm-none-eabi-size build/F030_bare.elf
   text    data     bss     dec     hex filename
   2428      12    1564    4004     fa4 build/F030_bare.elf

That is the basic size of an empty generated project just containing some drivers.

2. F030_inst Size with TRICE_OFF=1

./build.sh TRICE_OFF=1 :

arm-none-eabi-size build/F030_inst.elf
   text    data     bss     dec     hex filename
   2428      12    1564    4004     fa4 build/F030_inst.elf

This is exactly the same result, proofing that TRICE_OFF 1 is working correctly.

3. F030_inst with ring buffer

./build.sh:

arm-none-eabi-size out/F030_inst.elf
   text    data     bss     dec     hex filename
   9416      28    2692   12136    2f68 out/F030_inst.elf

This is about 7 KB Flash and 1.2 KB RAM size for the Trice library and we see:

“🐁 Speedy Gonzales” direct outout needs about 200 MCU clocks and not 500 as before.

7. Settings Conclusion

4-8 KB Flash and 1.2 KB RAM needed for the Trice library.
The RAM size is mainly influenced by the configured buffer sizes.
Switching off diagnostics and/or protection is ok for less memory needs and faster Trice execution after getting some experience with the project.

8. Legacy Trice Space Example (Old Version)

STM32CubeMX generated empty default project: Program Size: Code=2208 RO-data=236 RW-data=4 ZI-data=1636
Same project with default Trice instrumentation: Program Size: Code=2828 RO-data=236 RW-data=44 ZI-data=1836
Needed FLASH memory: 620 Bytes
Needed RAM: 40 Bytes plus 200 Bytes for the 2 times 100 Bytes double buffer
With increased/decreased buffers also more/less RAM is needed.
With each additional Trice macro a few additional FLASH memory bytes, like 10 assembler instructions, are needed.
No printf-like library code is used anymore.
No format strings go into the target code anymore.
In general Trice instrumentation reduces the needed memory compared to a printf-like implementation.

9. Memory Needs for Old Example 1

The following numbers are measured with a legacy encoding, showing that the instrumentation code can be even smaller.

Program Size (STM32-F030R8 demo project)	trice instrumentation	buffer size	compiler optimize for time	comment
Code=1592 RO-data=236 RW-data= 4 ZI-data=1028	none	0	off	CubeMX generated, no trice
Code=1712 RO-data=240 RW-data=24 ZI-data=1088	core	64	off	core added without trices
Code=3208 RO-data=240 RW-data=36 ZI-data=1540	TriceCheckSet()	512	off	TRICE_SHORT_MEMORY is 1 (small)
Code=3808 RO-data=240 RW-data=36 ZI-data=1540	TriceCheckSet()	512	on	TRICE_SHORT_MEMORY is 0 (fast)

The core instrumentation needs less 150 bytes FLASH and about 100 bytes RAM when buffer size is 64 bytes.
The about 50 trices in TriceCheckSet() allocate roughly 2100 (fast mode) or 1500 (small mode) bytes.
trices are removable without code changes with #define TRICE_OFF 1 before incude "trice.h" on file level or generally on project level.

10. Memory Needs for Old Example 2

Project	Compiler	Optimization	Link-Time-Optimization	Result	Remark
MDK-ARM_STM32F030_bareerated	CLANG v6.19	-Oz	yes	Code=1020 RO-data=196 RW-data=0 ZI-data=1024	This is the plain generated project without trice instrumentation.
MDK-ARM_STM32F030_instrumented	CLANG v6.19	-Oz	yes	Code=4726 RO-data=238 RW-data=16 ZI-data=4608	This is with full trice instrumentation with example messages.

The size need is less than 4 KB. See also Trice Project Image Size Optimization.
