FPGASID Support Thread (english)

What does it mean when the 3 voice LEDs are just blinking, seemingly independently, slightly faster than 1Hz.

I've got a 1MHz clock on pin 6. I've tied R/W to ground as I'm only writing to registers 0-0x18.

Audio output sits at a steady +5VDC. EXT In and Pot-pins are floating. Cap-pins are floating.

I'm getting /CS pulses that SEEM right (don't have a logic analyzer with a wide-enough bus to check everything at once).

Will check /CS against address pins, but I can't find any explanation to the LED blink behavior, at least not in English

That should be the "heartbeat" signalling. You can configure the LED behaviour in CONFIGURU,

provided it's the latest version of the F/W as well as of the tool itself.

Ok so it's normal, thanks. Thought it was some error message

I got it working now. Of course it was a bug in my shitty code

Also, I noticed the LEDs somehow change to voice gate indication once the song starts playing.

It's embarrassing how bad the timing is though, even if it's being triggered by an interrupt in the Arduino.

Probably due to some other issues with my code, but at least I know the schematics and hardware is working now

Thanks!

In the game "Montezuma's Revenge" the sound of the player's walking across the screen gets distorted after picking up the key on the first screen. Picking up the key plays a little tune, after that the walking sound is distorted. This only applies when the FPGASID is in 8580-mode. (Firmware revision 0A)
Is this a known issue?
