Does anybody know how to get gray-scale pixels on SH4-type fx-9860gii model calculators.
I've read that Kucalc got it working back in 2007 but that only for sh3. I know C and C++ but I don't know how to write assembly.
The Casio fx-9860 model series only has a monochrome LCD, therefore it can only display pixels in black and white, but a lot of people found ways to emulate tones of gray(gray-scale) on the LCDs.
You have to switch the pixels on and off at a high frequency to trick our eyes to see gray. A darker gray can be achieved by displaying the black pixels for a little while longer.
I've already tried doing this in C, but the flicker speed is not even close to the speed needed to achieve a gray looking pixel.
I know it's possible because people have already done it for the 9860G, and they also achieved gray-scale on the TI-83+ using the same technique.
I've seen it used in Doodle Jump and Mario Land CE and it looks awesome. Games look so much better with gray-scale.
Please reply if you have any information/comments about gray-scale on the SH4-type CPUs.
