AVR-Chat

All,

 as we're on the subject (my favourite), I thought I'd forward this link for
a website I setup on my server ;-
Www.Jarek.Synth.Net

he's build a complete MIDI synth on a single 90s8535.. I'm trying to get the
parts to build one and do some samples, its dinky!

Paul

Dingo,

Last time I asked Jarek, he said he didn't have any samples.
As the 8535 is now obsolete, I plan to 'port' the code to a MEGA16, I'll
then pass it to Jarek to publish.
It should be a very simple job.
Anyway, once I've done that I'll send him some samples to put up.

Paul

That is pretty cool, any photos and / or wav files of the output?

How about the Mega8535?

yep, but I only have some MEGA16s at home :-)

Hi, Paul

I look the schematic have a question.
Please tell me connect 74HC574 Q1-Q8 pin's parts is what ?

thanks

Luke,

> Please tell me connect 74HC574 Q1-Q8 pin's parts is what ?

sorry, I don't understand the question,
the 'Q' number insdie the device refers to the latch number inside the
device..
the 'Q' number on output refers to the 'bit' value where Q15 is the biggest
and Q0 is the smallest.

The 74hc574s are being used as a 16Bit DAC, its a cheap and fairly quick way
to do it.

Excuse to engilsh .
Because i want buy electronics to try .

Thank you much.

Luke,

ahh, the squares on the right of the 74hc574s?
Those are resistors, with different values (shown to the right) .

Paul

74HC574 is an octal D-type flip-flop.  D1 through D8 are the inputs and Q1 
through Q8 are the outputs of the flip-flops.  They are being used here in 
a standard R-2R ladder network D/A converter scheme.

Thanks Zack,
     
     Thank you teach me about 74HC574.
