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 !! Loic
