Need help with midio128..

[Guest eightlanemusic]

First excuse my bad english.

I need help on midio128 projekt.

How can i change the action on digital output pins?

It seems like the gate signals- comming from the latches of an Dout is some kind of pulsed/ modulated. Is it possible to turn the gates in to normal hi/ low behavior? I designd 2 little breadboards, 1 with pic/ midi and 2 dout modules and the other with a bunch of 4066 analog switches. All seem to work but the signal commin from the latches is even modulatet.

thanks ya for help...

Hi,

without loosing too much words: this is a design weakness which will be fixed in the next MIOS version. It's related to the way how additional components like the BankStick, the AOUT and the SID module are accessed from the core.

Since these components are not relevant for MIDIO128, just do the following: download the MIOS source code from sourceforge, open mios_srio.inc and remove the code between line 52 and 75 (the MIOS_SRIO_Prep_Loop)

Reassemble the code and convert it to a .syx file with "perl hex2syx.pl main.hex -os"

This change will be part of the next release.

The next release will also require to connect the SCLK line of the BankStick/AOUT/SID module to another pin. A hardware change for other modules won't be required.

Best Regards, Thorsten.
