Re: Five clock per pixel RLE mode

Well - there has been progress since this thread. I posted a moving polygon HEX file here

Re: Board revision requests

I was logging exact blanking timing from the hardware. The board between is a level shifter: The Uzebox is 5V and the Due SAM3X is 3.3V Due setup as SPI slave, feed the pixel clock into SPI clock, feed the blanking signal to MOSI: A poor man's logic analyser. And the green wire on the Due going to ...

Re: Uzebox Micro Handheld

Long time between drinks. Here is a photo of ROGUZE on the 320x240 lcd screen with a non-optimal pixel blending turned on. The blending is currently optimized to fit the 288/256 pixel screen of T2K into the 320 pixels. But you can see that it does work somewhat to fit the 360 pixel wide mode of Rogu...

Re: Mode 72 development

My next one after RLE is going to be super sized scaled sprites.

Think Space Harrier / Hangon / Outrun.

I'm no where near as good as you at pumping out code quickly though. So I wouldn't expect to see any Testarossas on the small screen any time soon though.

Re: SPIF gets cleared if ANY interrupt happens?

I concur the bootloader built in SD functions are the easiest thing to use. If you need absolute full speed you can turn the CRC checking off and then graft in the SD_Simple block reading commands. It is hand crafted assembly intended to get absolute minimum clocks per data. It also has "scatter/gat...

If it was only one of the six SD card that you couldn't get work you could probably just say it was a bad apple.

Or with the AVR Emulator in AVR Studio 4. It is meant to be perfect emulation of the chips its supports.

Re: SPIF gets cleared if ANY interrupt happens?

What does the ASM in the LSS file look like for that C?
