[KS0108-LCD Issue]

Hello mono and Tk.

I have 2 KS0108-Displays ( 128x64 , 2CS each ) with no wirring error ( quintuple check for a week now ) on a LPC17 .

I can't figure how to configure the lcd in the bootloader the right way .

One display with 128x64 and num_x = 1 work perfectly , I swaped the ribbon cable and the lcd ... both cable work and lcd are ok 

But when i try two displays , only one at a time is working , the one wich is on CS1 and CS2 line .

• TEST 1 : lcd_width 128x64  AND   lcd_num_x = 2    :
• work only with the lcd wich is connected to cs 1 and 2 and print  LCD #1.1 ready . LCD wich is on cs3 and cs 4 is blank
• If i swap the j15a and J15b ( but don't touch j28 ), the second LCD print  LCD #2.1 ready  and the first one wich is now on cs3 and cs 4 is blank
•  
• TEST 2 :  lcd_width255x64  AND   lcd_num_x = 1   OR lcd_num_x = 2
  • all lcd are blank 

I traced CS3 ( WS ) and CS4 ( MCLK ) on the LPC17 and it seem ok .

I use bootloader 1018 and MBNG 1.036

Any idea on what i am missing ?

Thank you , 

Hope you're all ok !!
