Touch Panel:PenMount 6000/9000

CX700 ubuntu 8.10 vga driver set RandR to false by default, but touch driver will detect RandR automatically.

if using those driver together, X window will crash.

to solve this problem, we asked touch vendor to modified driver to disable RandR detected.

Touch Panel Driver 可以從 1. OS 2. Chipset 來做判斷

• Linux (OS)

視乎其 Xorg 版本, 由於 Touch panel 由本質上來看可以當作是一個滑鼠, 所以對 Kernel version 來說,沒有太多關係.但是原廠(PenMount)為了 end-user 可能不是每個人都那麼了解 xorg 所以出了各個distribution的Driver像是 Fedora 2,3,4,5 之類的, 但其實他們之間的 xorg 版本都沒什麼差異 Chipset

   目前我們所使用的 chipset 分為兩種: 1. dmc9000(RS232)  2. dmc6000(USB)
   如何使用這兩種不一樣的driver只有差別在 xorg 中的設定
   1. dmc9000(RS232): Option  "Device"    "/dev/ttyS0"  #ttys0=COM1,ttys1=COM2   <= 藉由 rs232去控制
   2. dmc6000(USB):   Option  "Device"    "/dev/input/event0"                    <= 將 usb 視為 event

Driver Supported:

   1.dmc9000: Redhat9, Fedora Core3, 4, 5
   2.dmc6000: Fedora Core 4, 5, 6   Xorg6.8

• WinCE(OS)

無論是 4.2 或是 5.0 都是把 driver 透過 CEC Editor 把driver 載到 Platform Builder 裡面再加到所要編譯的 image 就可以使用了 ( 須注意一點, WinCE 中 COM1 預設是 WincCE 用來做 Debug 的埠口, 所以要從 COM2 算起 ) Driver Supported:

   1.dmc9000: WinCE4.2, WinCE5.0
   2.dmc6000: WinCE4.2, WinCE5.0

Touch panel needs 5V+ to turn on. 5V+ makes "power on by ring" estimate to "TRUE", so system will be restart .
Disable the option "Power on by ring" in BIOS could solved this problem.

#vi /boot/grub/menu.lst

Add "8250.nr_uarts=6" in the kernel line as below picture:

#reboot

And then you can use 6 COM ports.
