qq2440 + iGo8 + bluetooth howto

How the stuff works

Part 1: iGo

First of all you need iGo 8 on SD card. In iGo8 install directory (StorageCard/NavNgo/iGO8) find file SYS.TXT and open it. Change/add the following:

[interface]
resolution_dir="800_480"
vga=0

[rawdisplay]
highres=0
screen_x=800
screen_y=480

If something missing – add it, if something present – change it. 800x480 – my screen resolution. If you have different resolution – change this numbers to yours. Now you should be able to start iGo.

Part2: BT Dongle

Open WinCE platform builder.
Open your project.
Open “Communication services and networking – Networking PAN – Bluetooth – Bluetooth protocol stack with transport driver support”.
Delete all except “Bluetooth stack with integrated USB driver”.
Now clean and build your platform.
After building and loading new platform you should be able to start Bluetooth dongle.
Go to “Settings – Control panel”. Double click on “Bluetooth device”. In opened window press “Scan Device”. You should view Bluetooth devices in range.

Part3: You need to open virtual COM port and associate it with Bluetooth. I’ll describe it later

GPS and qq2440 (continue)

GPS works. I have connected bluetooth USB dongle and bluetooth GPS. And there is a sample in Windows CE platform builder for virtual com port. I made some changes in it. Here is the results.

Navngo IGo 8 on qq2440

IGo 8 is running on qq2440. Finally something good. Now I'm looking for RS232 GPS.

Buildroot for qq2440 (continue)

I compiled buildroot with external toolchain, because of internal buildroot bug. It seems to be exist in last release. When I tried to compile buildroot and toolchain for arm - it didn't work. My board didnt recognize this filesystem.
Yesterday I downloaded buildroot snapshot "buildroot-20090420". Internal toolchain is OK now. And almost everything is compiled now. You only need to choose target architecture "arm" and cpu "arm920t".
