Question on MBSEQv4 LED matrix wiring

[jjonas]

Hi,

in the pdf on the Wilba frontpanel button/LED matrix, the dual-color GPx LEDs are said to be hardcoded into the firmware. But in the said pdf the information on how to wire them is confusing. In the schematic the dual-color LEDs are wired to pins D4-D7, but in the chart next to the schematic they are wired to pins D3-D0. The question is: which version in the linked pdf – schematic or chart – is the one that I should use if I want to make a DIY frontpanel with DIO matrix?

Hi,

thanks for pointing this out!

The table was correct, the schematic wrong. It's corrected now: http://www.ucapps.de/midibox_seq/mbseq_v4_dio_wilba_layout.pdf
