I have a couple of CFAH2004 displays and decided to wire them up to my linux box (fedora 4). I wired them up to the parallel port and a molex by basically tying pins 2,15 to 5v and 1,3,5,16 to ground. Then the rest of the pins to the parallel port. pp16-4,pp1-6,pp2-7 etc to pp9-14. I have wired up both displays like this.
Both displays have the same problem. When I power the computer up I get the 1st and 3rd lines turn on. All sweet. I then start LCDproc using the HD44780 driver, port 378, 8bit display. The screen flickers for a bit and then returns to the 1st and 3rd lines black. when I start the client up all that happens is the screen fades and flickers in and out in a random cycle (1-2 sec period). There is no details finer that the base 20x4 level. no char's. The only extra features is the 1/3 of lines 2,4 are activated.
I have played with parallel port settings and lcdproc version and setting but no luck. Any ideas?
Thanks
