| Has anyone used the Epson S1D13700?? |

Hi,
I have just purchased a Crystalfontz CFAG320240CX (S1D13700) 320X240 LCD graphics display which "supposedly" is compatible with its predecessor controller (Epson SED1335) I believe that a simple driver for this one already exists in the CCS drivers list (SED1335.c) However the more I investigate into this, I find, that quite a few people on various newsgroups are saying that there are some very distinct differences in the command set and timing issues between these controllers. Because this is totally new territory for me, as I have never written any graphics drivers before, I wanted to pose the question within this group to see if anyone else has already tackled this issue, specially using the CCS compiler. As usual, any hints or advise is greatly appreciated.  |

| S1D13700 driver |

There is a problem: The driver for SED1335 from CCS, don't work correctly with S1D13700. I have just corrected the problem. Here is the code for S1D13700:

| SED1335 and S1D13700 software incompatibilities |
| Posted: Thu May 10, 2007 1:52 am |
|
|
Hello all,
I discovered a slight difference that may cause some headache for those who are programming the CGRAM of the S1D13700.
I have a board that was connected to a SED1335 (it was a screen from Crystal Clear Technologies. CCT G2432X15), but as this IC became obsolete by end 2005, I had to move to an updated version of this screen (G2432X17).
In the SED1335, bit M1 of the SYSTEM_SET register could be selected to have D6 correction over the CGRAM only, allowing the placement of the configurable character mask in a coninuous memory space.
However, in the S1D13700, the D6 correction applies to ALL, and if you use this "feature", you will have all your character codes partially shifted out, ending in a sort of ASCII mixture.
In the first S1D13700 technical manual, it was asserted that bit M1 could be configured in the same way as the SED1335. Mysteriously, this feature disappeared in subsequent revisions. The old M1 bit was described as "reserved", and it should be set to 0.
So, if you are using an SED1335 and you are setting a 1 to M1 bit of the SYSTEM_SET register, you will have to do a change in your software when moving to the S1D13700.
Regards,
Juan Ramón

Hi Eduardo,
Today I have found your post here and was very glad to find it . I have a TOPWAY LM2088E with S1D13700 (I think) (there is EPSON D1370002A1 written on the chip)
I have made the hardware as;
Pin_B5 to RD
Pin_B1 to WR
Pin_B2 to CS
Pin_B4 to A0
Pin_C3 to RST
pin_D0 to DB0
.
.
Pin_D7 to DB7
I am using a PIC18F452. I included your "SED13700.C " into my code. But when I compile it, the CCS compiler halts, freezez. Then I need to close the compiler and restart.
When I just compile my code without including the SED13700.C the CCS compiler works fine. but that time of course I have no LCD driver.
have any idea ? I couldnt seen even a dot on my new LCD yet  please help if you can... I should be doing something wrong but I couldnt find.
Regards,

| I'm disappointed that this controller is only good for fairly small sizes of display. I've got a couple of 640x480 RGB panels that I'd love to get into use, but it would take a serious memory/driver system to get them operating. I can imagine a PIC just telling the graphic system what to do, though, if the mechanics of running the display were handled by something else. |

Hi,
I have taken Eduardo's code too. XD. But I have some troubles. The display don't show anything. I have a DISPLAYTECH 240320G LCD, and I would like to know what are the differences between SED1335 and S1D13700 to check the library.
Should I change the system_setup parameters or is standard for all the LCD with S1D13700 chip.
Thanks |
