Hi, I'm looking for a small scripting engine implementation for my embedded project running on STM32F103T6 MCU @ 72MHz and FreeRTOS 6.0.4 and ST library 3.2.0. Right now, I'm using a derivate of basic language with code: c=0 for d=1 to 10000 set_onboard_led c if c=0 then c=1 else c=0 next d end and get performance roughly 1 millisecond per 1 loop. The project is level 2 optimized in GCC (-O2). The script is running as an operating system task. I'm looking for an alternative scripting solution that can do roughly 20 microseconds per 1 loop. Thanks in advance!

You'll want to configure it to use integer numbers (by default it uses floating point).

But right now I have not seen any good benchamarks on Internet. I'd not consider porting the language just to see that it is too slow :) Pawn looks also interesting - has anyone ported it to STM32 or cortex- m3 platform?

I don't know about its performance (though it will be slower if you don't configure for integers), but there should be no problem getting it to build.
