说明： 界面和通讯交互式工作的例程，
供参考设计，有很大的借鉴哦
(Interactive interface and communications work routines for the reference design, there are a lot of reference Oh)

=========
This directory contains two simple projects to illustrate ARM/Thumb interworking
with C code. CodeWarrior project files and script (batch) files are provided.
For details, see the Developer Guide, Chapter 3, "Interworking ARM and Thumb".
The two projects show:
1. An ARM main() calling a Thumb subroutine
2. A Thumb main() calling an ARM subroutine
In both cases, the linker pulls in the appropriate C library, and adds interworking
veneers. The added veneers are shown with the linker '-info veneers' option.
1. ARM (main) code calling a Thumb subroutine
The two files in this project are armmain.c and thumbsub.c.
Use the CodeWarrior project file ARM_to_Thumb.mcp to build the project.
Alternatively execute the command-line script armtothumb.bat.
armcc -c -g -O1 -apcs /interwork armmain.c
tcc -c -g -O1 -apcs /interwork thumbsub.c
armlink armmain.o thumbsub.o -o armtothumb.axf -info veneers
2. Thumb (main) code calling an ARM subroutine
The two files in this project are thumbain.c and armsub.c.
Use the CodeWarrior project file Thumb_to_ARM.mcp to build the project.
Alternatively execute the command-line script thumbtoarm.bat:
tcc -c -g -O1 -apcs /interwork thumbmain.c
armcc -c -g -O1 -apcs /interwork armsub.c
armlink thumbmain.o armsub.o -o thumbtoarm.axf -info veneers
