(...) <snip> (...) This is really interesting. If I understand correctly, to get colors, or at least shades of grey, you have to refresh the screen quickly and the "darker" the pixel, the more often it shows up in the pattern.

(...) John - I know you don't like this and I agree that the best solution is NI changing their compiler to allow extending firmware with new syscalls. The way things work, I'm afraid, this will not happen anytime soon. I'm trying to suggest (...) (19 years ago, 22-Mar-07, to lugnet.robotics.nxt)

|
Here's a trick to get a faster rate on the LCD display refresh. It currently takes 16 milliseconds to refresh the NXT LCD. 16 "messages" are sent to the LCD. One message is sent per millisecond. There are two messages from the ARM to the LCD for (...) (19 years ago, 22-Mar-07, to lugnet.robotics.nxt.nxthacking)

Do we loose points for melting the eggs? At any rate, it makes the foil stay on better. ;-) --Peter (19 years ago, 22-Mar-07, to lugnet.events.brickfest, lugnet.robotics, FTX)

(...) I guess what I'm saying is '<<=', 'OP_ASL' and 'OP_LSL' are all the same thing (zero fill). '>>=' means either 'OP_ASR' (smear fill) or 'OP_LSR' (zero fill) depending on whether your target is signed or not. If you wanted direct equivalents (...)

(...) Having used shifts in Z80 assembly before, I can see the uses of the different types. However, I can't see how I'd want anything other than arithmetical in the NBC opcodes. The only times I used logical, rotating, or with-carry-bit shifts was (...) (19 years ago, 21-Mar-07, to lugnet.robotics.nxt.nxthacking)
