595 DoutX4**** c-code
Pin1-7 = O0-O7 = D0-D7 but react on “MIOS32_DOUT_PinSet( 7-0 , 1);”
?is there a switch that inverses that?
i just for info: have a fabricated pcb here, and it would be nice i dont have to redoo the hardware, its a led-matrix > http://wiki.midibox.org/doku.php?id=cc-looper
Hi Mike,
There’s no “switch” or define for this.
It was made like this to match the old PIC DOUT pinout.

This helper was not implemented. And the problem is that MIOS32_DOUT_SR_xx use this array but not the MIOS32_DOUT_Pin_xx
But you use the right method 
except that it works only for pin 0 to 7.
If you want to do it on all the pins you have to include the SR number just implent something like this.
e.g.
u32 PIN\_REVERT(u32 pin) { u8 num\_sr = pin\>\>3;// divide by 8 pin %=8;// modulo by 8 return (u32)((num\_sr\<\<3) + (7-pin)); }
then use it:
MIOS32\_DOUT\_PinSet(PIN\_REVERT(pin), value);
i understand, i will implement your PIN_REVERT Function THX!
