Another thing I've done is write out a number where the upper byte indicates a position in (...) (26 years ago, 16-Mar-99, to lugnet.robotics.rcx.legos)

I did that too. In my case, the lower byte was the priority (...) (26 years ago, 16-Mar-99, to lugnet.robotics.rcx.legos)

Another thing you could do is print messages out the IR port; but I'm not sure how it would (...) (26 years ago, 17-Mar-99, to lugnet.robotics.rcx.legos)

| | | | | (...) However, last night, I wrote a brute force (spin loop) msleep which works fine in the scheduler. I found that 800 iterations of an empty for loop with a 16 bit index comes pretty close to 1ms. Granted, I cheated a little, knowing that the (...)

I carefully looked at the opcodes, and found that the shortest opcodes are all 2 bytes, and hand-coded the 2 byte instruction that jumps to itself. The (...)
