IoT smart RGB lights

Overview

By adding peripheral circuits to the module WB3S, the effect of intelligent colorful lights can be achieved. QQ picture 20201207074034.png For voltage conversion, the 5V voltage is converted to 3.3V through the voltage regulator U1. The USB port is the external power supply, and the two sets of capacitors play a filtering role.

Here RGB is a common anode circuit, and the tail end is connected to the output end of the MOS tube.

How does the kernel driver work?
I found a kernel driver code on the Internet. I set up the environment XP SP3+VC++6.0+WINDDK FOR XP +DRIVESTUDIO3.2. The code ran and generated a .SYS file, but I don't know how to run it. Can anyone
Who has the telent client code for WinCE?
WinCE C# code, thank you if you don't have enough points, please add more.

Fuse blown self-healing circuit
The working principle of the circuit of the device is shown in Figure 6. When the fuse FU1 is intact, the neon bulb ND is short-circuited and does not light up, and at the same time, the ① and ② pins
Is my interrupt response time normal?
It takes 1.4ms from the first instruction of ISR to the first instruction of interrupt thread IST response (setting an IO output). Some friends in the forum have tested it and said it only takes 400us
