this board is intended to drive the NL8060BC26-17, which uses a CMOS-Level 3v3 Interface instead of the LVDS

lukier:

some update on my sil151 adapter.

Rev.A has the following issues:

*) HSYNC / VSYNC Lines were swapped
*) Hotplugdetection (Pin19) on HDMI was not connected -> Fix was to add 1k to Pin18 (V+)
*) Rev.A uses a single Powersupply (3V3) whereas in the original Design the TFT is driven with 5V Supply and 3v3 Signals. I did modify one Board and added a 3v3 LDO to power the board and connected 5v directly to the FPC Connector

(I attached a picture - this is how i inteded to mount the board, which didn't worked out)

=> after this modifications the board is working. However the FPC connector is loose and maybe I damaged the cable already so It is not yet working reliable.

After I getting the Display working. I swapped the motherboard with an Motherboard from a Lenovo Thinkcenter M92p - the nice thing about these motherboards they have the Q77 Chipset, 2x PCI and an internal Displayport. On the ugly side - Powersuppy, PCFrontPanel and FrontUSB Headers are not standard. For Powersupply I ordered an adapter kabel - for the headers I did swap the connector pins in the cables to match the pinout.

 I installed Win7 Pro 32 Bit and the dxl driver set (v3) - and on top of that the ZtiLecroyFPanelFix-2019-02-24.zip - apart from the touchscreen everything was working smoothly.

but .. I assembled everything back together and installed the Touchscreen drivers - and after this somehow the Frontpanel stopped working. No LEDs no response whatsoever. I tried reinstalling the driver several times (starting safe mode and removing the driver). But I could not fix the issue.

My fist QUESTION: When I try to remove the FrontPanel driver from the Device Manager - I do get a Windows BlueScreen. Has anyone experienced a similar problem?

My second QUESTION: I did install the 3M TouchPanel drivers working on the Serial Interface. They do work on the Windows Desktop but when I start the DSO Applikation they cursor movement from the Touchpad stopps during Application Startup ... after quitting the DSO Application the Touchpanel remains unresponsive until i reboot the OS.

georgo:
