TinyBasic

Simple implementation of Basic to controln Arduino Micro or STM32F103 mcus

Speed test

(current implementation optimizes interpretation of tokens, but does not hard link variables and labels yet)

simple code used:

10 x = 100000
20 if x%5000=0;print x
30 x = x-1
40 if x>=0; goto 20

i.e. about 4 statements per iteration

• on STM32 with -O0: 10 sec
• on STM32 with -O1: 6 sec
• on STM32 with -O2: 5 sec
• on STM32 with -O3: 4 sec
• on Arduino Micro (x=30000): 7 sec (i.e. 23 for 100000)

i.e. roughly 100000 statements per second on STM32 achievable
