Bought the female and male pin header from Aliexpress that is compatible with Omega 1 in case anyone is interested.

After reading the datasheet looks like I'm using the wrong decode mode. Here are the steps in case anyone is having the same problem

Following is the wiring

Following is the test bash script



#!/bin/sh
#set power ON
spi-tool -b 0 -d 1 write 0x0C 0x1

#set scan limit
spi-tool -b 0 -d 1 write 0x0B 0x0f

#decode mode
spi-tool -b 0 -d 1 write 0x09 0x01


#Set each display in use to blank
for i in 1 2 3 4 5 6 7 8 9
do
  spi-tool -b 0 -d 1 write 0x$i 0x0  
done

for i in 1 2 3 4 5 6 7 8
do
  spi-tool -b 0 -d 1 write 0x$i 0x11
done

sleep 1

for j in 0x11 0x22 0x33 0x44 0x55 0x66 0x77 0x88 0x99 0xAA 0xBB 0xCC 0xDD 0xEE 0xFF
 do
  for i in 1 2 3 4 5 6 7 8
  do
    spi-tool -b 0 -d 1 write 0x$i $j
  done
  sleep 1
 done
