Device driver for native mode UARTs of PCIe95x/200 family devices.
Installation
____________
1. Install Windows CE 4.2 Platform Builder (PB) to hard disc. Note the
WINCEROOT i.e. the path where the CE 4.2 is installed (generally C:\WINCE420).
2. Run the batch file "CopyDriverToWinCERoot.bat" which will prompt the
user to enter the WINCEROOT. The batch file will then copy all files
and subfolders of the source code to the Windows CE 4.2 root directory. The
following directory structure shall be seen:
C:\WINCE420\OXSEMI
|------UARTS
| |
| |-----....
| |-----pcie950_uart
| |
| |---------pcie950_bus
| |---------pcie950_isr
| |---------pcie950_ser
| |-----....
|------APPS
|
|-----suart
|------....
3. Start (configure and rebuild if required) PB
4. Click “File->Manage Catalog Features” to start “Manage Catalog Features” dialog
5. Click “Import…” button to start “Import Catalog Features” dialog and import
cec files of “pci954_uart.cec” under the “uarts” subdirectory
6. Select the target configuration (for example "CEPC:X86 Win32 (WCE x86) Release").
by click "Target->Set Active Configuration.."
7. Add PCIe950 feature to OS by right-clicking on the pcie950_uart feature logo
in catalogue view and choose “Add to Platform”
8. Start platform build process by clicking “Build->Rebuild Platform”.

Interrupt triggering and flow control levels
____________________________________________
Four level control values can be defined in "pci954_uart.reg" file (brackets
indicate the correcponding 16950 registers, to where the values will be stored
when device driver being loaded):
"RxIntTrigLevel" ------ Receive Interrupt Triggering Level (RTL)
"TxIntTrigLevel" ------ Transmit Interrupt Triggering Level (TTL)
"FlowCtrlLowLevel" ---- Automatic Flow Control Lower Trigger Level (FCL)
"FlowCtrlHighLevel" --- Automatic Flow Control Higher Trigger Level (FCH)
The level control values defined in pci954_uart.reg file shall be used as default
values by all UART channels.
The level value are expressed in hexadecimal, NOT DECIMAL. For example, to set
the Receive Interrupt Triggering Level to 95, the following line should exist
under the corresponging key:
"RxIntTrigLevel"=dword:5F
If required, the level control values of each UART channel can be changed
individually using "SUART", which runs on the target OS.
Interrupt triggering and flow control levels
____________________________________________
Baudrate Map List can be defined in "pci954_uart.reg" file using the two registry
values:
"BaudrateMapListFrom" --- Baudrate Map List for From baudrates
"BaudrateMapListTo" ----- Baudrate Map List for To baudrates
The baudrate map list defined in pci954_uart.reg file shall be used as default by
all UART channels.
The baudrate values are expressed in decimal. For example, to map baudrates of
230,400 and 1,843,200 to baudrates of 1,200 and 2,400, the following lines
should exist under the corresponding key:
"BaudrateMapListFrom"=multi_sz:"1200","2400"
"BaudrateMapListTo"=multi_sz:"230400","1843200"
If required, the baudrate map list of each UART channel can be modified
individually using "SUART", which runs on the target OS.

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
