OK, I get it:

reg open \Drivers\BuiltIn\PicoCOMA5\I2C1_V110
reg del val Flags
reg set val ClockFreq dword 200000
reg set val Index 2
reg set val PinSCL dword 50
reg set val PinSDA dword 49

Hi there

how can I reconfigure J1 Pin 30 (CAN0_TX) to I2C0_SDA and J1 Pin 31 (CAN0_RX) to I2C0_SCL? And where in the registry can I configure the I2C0, things like IntPullUp and ClockFreq?

Best regards

The cable was about 30cm long. I use the same cable for NetDCU8 and PicoCOM4, we have the same plug on our PicoCOM4 adaption like J3 on NetDCU8 (pincompatible). I have no flickering when i move the cable. I have also tried some cable ferrit without success.
Now, i have shorten the cable to 10cm (5cm is not doable) again without success. I have also tried to toggle the clock polarity, again.

I have tried that:

reg open \drivers\display\samsung
reg create key mode101
reg set value name string "DATAVISION DTFS104F0VLX"
reg set value EFW dword 20
reg set value BFW dword 20
reg set value LPP dword 480
reg set value msignal dword 2
reg set value rows dword 480
reg set value width dword 211
reg set value height dword 158
reg set value contrastenable dword 0
reg set value contrastvalue dword 0
reg set value type dword 6
reg set value config dword 0x00700000
reg set value columns dword 640
reg set value HSW dword 35
reg set value bpp dword 16
reg set value PPL dword 640
reg set value lcdclk dword 25
reg set value VSW dword 2
reg set value BLW dword 60
reg set value ELW dword 60
reg set value EnableCursor dword 1
display mode set 101
reg save
reboot

mode101 was not created befor i send this. Is this looking correct for you?

I have tried this values but it's not making a difference. I think i have to give up and searching an other 10,4" Display.
Thanks for your help.

I don't have HSync/VSync Signals on that display. I have only M-Signal connected.

Display driver settings:
reg set value name string "DATAVISION DTFS104F0VLX"
reg set value EFW dword 80
reg set value BFW dword 80
reg set value LPP dword 480
reg set value msignal dword 2
reg set value rows dword 480
reg set value width dword 211
reg set value height dword 158
reg set value contrastenable dword 0
reg set value contrastvalue dword 0
reg set value type dword 6
reg set value config dword 0x00700000
reg set value columns dword 640
reg set value HSW dword 35
reg set value bpp dword 16
reg set value PPL dword 640
reg set value lcdclk dword 25
reg set value VSW dword 2
reg set value BLW dword 5
reg set value ELW dword 5
reg set value EnableCursor dword 1

With all this driver settings the Display works on a PicoCOM4 but not on a NetDCU8. I don't know if msignal=DWORD:0 does work on PicoCOM4. I didn't try that because msignal=DWORD:2 is working well on PicoCOM4.

Thank you.
I have checked the registry settings and i get the same values like F&S, who has writen this driver specialy for the NetDCU8 on our request.
I'm wondering why is this driver running on a PicoCOM4 and not on NetDCU8 with the same signal connections.

"Data enable signal" from Display is connected to "M" (NetDCU8: J3 / Pin 21),
"Dot clock" from Display is connected to "CLP" (NetDCU8: J3 / Pin 19),
I don't have any HSync/VSync Signals on the Display.
Changeing clock polarity doesn't make a difference, also changeing the sync, what doesn't surprise when i didn't connect this signals.
Is there a possible way to change data enable polarity? I tried with parameter "MSignal" in display driver (0, 1 and 2) but also make no difference.

OK, if they don't have the right polarity, can i fix that with the software driver? Witch parameter is for the polarity of the clock and the sync? And what did u mean with sync, is that the data enable signal?

I tryed any single value between 10 and 40:

lcdclk / measured clockfrequency
10...11 / 10.2MHz
12...14 / 12.75MHz
15...21 / 17MHz
22...38 / 25.5MHz
39...40 / 51MHz

And the Display looks bad on any value I tryed:

at 25MHz look at my first post
at 17Mhz look at my second post
at 12, 10, 51MHz it's undiscriptable bad

Thanks for your awnser.

The resolution is 640x480. The datasheet of the display is saying minimul clock frequency is 21MHz. If i lower to this (lcdclk dword 21) the main flickering is away, but the screens is repeating in two areas some columns, it looks splitted, and in this two areas its flickering all the time. The picture is then widther than the screen.

Hi

We have a problem with a new 10,4 Inch Display. F&S has written a new driver for this Display and NetDCU8. Now, it's working good with PicoCOM4, but when i plug this Display on the NetDCU8 we have a flickering while booting up and after the boot we also have flickering when we move the mouse. If we don't do anything, the Display is looking good.
Has somebody any idea how to solve this problem?

Thanks.
Best regards!

Thank u very much, this is working perfect!

I'm trying to protect the FTP of a PicoCOM4 Modul by Username and Password.

The following settings i have already donne in the registry:

HKEY_LOCAL_MACHINE\COMM\FTPD
AllowAnonymous dword 0
UserList string Adrian

My problem now is, where can i create this user 'Adrian' and set his password?

Thank you for that quick awnser, it works very well!

Hello,
is it possible to show chinese signs an a PicoCOM4 with kernel XIPNKPC4_CORE_CF35_121029 by changing the font to "Simsun" as example or did we need an other kernel to do that?

Best regards
Adrian

Hello,

this is not working! This registry entry disables the USB device.
I still haven't a solution.

Best regards

Can I reconfigurate the USB device to a second USB host?

Is this the registry entry to do that (this is from NETDCU8):

Reg open \Drivers\BuiltIn\USBFN
Reg set val Flags dword 4

And what have I to do with PIN 23 (CNX / PB30)? Can I let it open?
