ClewareUSB.Net

An implementation of the Cleware USB Stoplight (USB-Ampel) in .NET

Requirements

This package requires a .Net HID Libary found here:
https://github.com/mikeobrien/HidLibrary

Using

using the Ampel factory to get the first instance or all usb instances. Both methods will return an ISwitchable Object. Using the interface set or clear the device state.

ISwitchable device = AmpelFactory.GetAllDevices();
device.SetState(ISwitchable.Status.Red,ISwitchable.Pulse.Off);
device.Clear();

USB-Ampel Protocols

USB-TrafficLights S

Thanks to https://github.com/holgero/ClewareUSB for providing the java version and initial documention to get the light working.

Identifiers

These may be the same for all Cleware Ampel devices but without the physical products I can not test this.

VID 0x0D50
DID 0x0008

Commands

The USB command structure consists of 4 bytes. The first two bytes are always 0, the third byte is the LED address and the last is the pulse duration.

LED Address

• Red: 0x010
• Yellow: 0x011
• Green: 0x012

Pulse duration

• Off 0x000
• Solid 0x001
• 0.5 Seconds 0x001
• 1 Second 0x0011
• 1.5 Seconds 0x012
• 2 Seconds 0x013
• 2.5 Seconds 0x014
• 3 Seconds 0x015
• 3.5 Seconds 0x016
• 4 Seconds 0x017
• 4.5 Seconds 0x018
• 5 Seconds 0x019
• 5.5 Seconds 0x01A
• 6 Seconds 0x01B
• 6.5 Seconds 0x01C
• 7 Seconds 0x01D
• 7.5 Seconds 0x01E
• 8 Seconds 0x01F

The final command will look something like

device.Write(new byte[]{0,0,0x010,1});
