Might anybody help me???

I use STR710, ARM core.

Development tool is IAR Embedded Workbench.

ST's examples totally use ARM instruction.

May I use Thumb instruction? Anyone has example of STR710 in instruction Thumb, please give me some example. Thanks so much.

The CPU in STR71x microntrollers is ARM7TDMI which supports the THUMB instruction set. The IAR development tools support code generation for ARM and THUMB instruction sets. You should consult documentation that comes with IAR tools to see how it's done.

I have used ARM and THUMB code generated by IAR tools with an STR710 microcontroller without any problems.
