morphing aliens (8x8 led matrix & ATtiny2313)

Some alien figures morphing from one to another, on an 8x8 dot matrix display.
The code is written in assembly and the MCU is an 8bit AVR (attiny2313).

PWM right?

[pvarelas]

@casvanmarcel Actually its a different method, called "Mirrored Image Bit Angle Modulation" or just MIBAM. It's way more efficient than PWM... ;-)

[casvanmarcel]

@pvarelas I see :) I googled it. Do you have any experience with MIBAM on PICs ? (uC from microchip) or how do I use it? do you use the PWM built into the AVR to generate the interrupts for MIBAM or is it done by hand in software ?

[pvarelas]

@casvanmarcel It's more than ten years since I last used a PIC and I can't help you with them... I do not use the built-in PWM of the AVR. I only use the overflow interrupt of a timer. Everything is implemented in software. I could email you the source code if you wish... it's written in the assembly language but it's well commented ;-)

@geobaboul Thanks man! I guess that was an expession of awe ;-)

[casvanmarcel]

@pvarelas well if it's not too much to ask that would be awsome :) any help is greatly apreciated :D I'll PM you my email

Καλά, αυτό τα σπάει. Και σ' αυτό το βίντεο φαίνεται πολύ καλύτερα.
