Hope this is a place we can meet to exchange some experience.
I have been developing Windows CE for a few years. I haven't touched Windows CE 6.0 yet, making own BSP on WinCE 5.0 has occupied lots of my time.
I am developing a handheld device with a GPS module, the purpose for this platform is to develop a good power management hardware and software design which includes some drivers for battery, backlight, charging, power management chip, DVS (Dynamic Voltage and Frequency Scaling) in kernel and sleep mode supporting.
Later I will develop a platform for industry applications which will include mutiple (4/8) RS232/RS485 ports, wirelss, Bluetooth etc.
