Hello,
Is it possible to know where " #define PIN_OTHER_SPI_nCS 53 " should be connected to the DMDCON ? I don't see a free pin on this connector.

Re: DMD Brightness control

Hi Stryker,
Ok, I have seen the post at the start of this thread.
I have purchased my DMD 2 weeks ago, but there are no resistor on the DMDCON.
On Freetronic site, there are no Resistor on the DMDCON connector drawing pdf.
Is it possible to update the drawing.
