(...) int is defined as the natural width of the processor, which on a 16-bit processor is 16 bits. longs are 64 bits on some machines as well, so you can't assume it is always 32 bits -- if your code cares, use sizeof. (...) 32-bit math on the H8 (...) (22 years ago, 12-Jul-02, to lugnet.robotics.rcx.legos)

That is very interesting Jason. It is interesting that mm_free_mem() returns a 16bit value using a 32bit return code. Both int and long are 32bit value on most computers/compilers these days; short would be a 16bit value; and char would be an 8bit (...) (22 years ago, 11-Jul-02, to lugnet.robotics.rcx.legos)

While the declaration for mm_free_mem is int mm_free_mem(void) The fact is that the RCX has only 32K of memory available. 32K in hex is 0x8000... there's never a need for more than 4 digits in hex. Looking at key_handler() in kernel/program.c (the (...) (22 years ago, 11-Jul-02, to lugnet.robotics.rcx.legos)

Albert Huang, Sorry for the confusion. "most significant" = upper 16 bits and "least significant" = lower 16 bits (the free memory is a 32 bit value). If you write the values out, you will get the 32 bit value (both values are hex) ... for example: (...) (22 years ago, 11-Jul-02, to lugnet.robotics.rcx.legos)

Joseph, Not to add too much work load, if you have a chance could you give an overview of the proposals out there for the task scheduling and sensor modifications (if any).
