Uninstall Hidden USB drivers from Device Manager

Very often when using a USB to RS232 device for hardware troubleshooting, a virtual com port number will be generated. If the device is removed and plugged to another USB port, Windows will install another set of drivers for the USB device, resulting in a new com port number assigned. Over along period of time, you may have a lot of unwanted drivers installed with you realising. This is because they are all hidden inside the Device Manager.

Remove Device Driver Manually

To get rid of unwanted drivers manually, devices, or services, use the following steps:

  1. Open the Start menu and choose Run.
  2. Type in “cmd“, right click the cmd terminal icon and right click “Run as administrator“.
  3. At the command prompt, type in “set devmgr_show_nonpresent_devices=1” and press Enter. (Note that nothing seems to happen. This is expected. You are actually setting an environment variable which is going to help you to see hidden devices.)
  4. On the next command prompt line, type “devmgmt.msc” and press Enter. This will launch the Windows Device Manager Console.
  5. In the Device Manager Console, from the View menu, select Show Hidden Devices.

Software Tool to help remove unused device driver

This software do the same as above. A faster way to remove a list of hidden devices that are not in use.

I2C Communication

I2C Physical Signal

I2C Lockup

I2C can get lockup and hang the whole I2C bus due to communication error. This is due to noise or incorrect signalling resulting in slave waiting for clock cycle, when the master already finish its clocking. The following are some of the common reasons for the communication error.

  • Too much capacitance on the bus.
  • Communication speed too high.

It is important to also program your codes to handle possible bus hang. You can clock out at least 10 clock cycle to clear the bus.

Solution

A common problem is that the pull up resistor on the bus is too low. This results in a slow slew rate. The digital signal is not sharp enough. Use a 1Kohm pull up resistor for both the SDA and SCK. It is the most common design problem I have encounter. I always put a pullup resistor value too high. 3.3Kohm can be too high.

Hand Gesture Command Control

This board feature a RGB Infrared IR gesture sensor and motion direction recognition module.

The chip used is GY-9960-3.3 APDS-9960, interface via I2C

Installation

The installation is simple. It is design to be compatible to all evaluator lift system.

Switch is dry contact and can easily to integrate to any existing elevator lift system or other electronic/electrical system that uses switches to operate.

You can install the switches as additional operating panel without removing your existing lift button panel. It is that simple.

This touch-free switch can easily fit into a wide range of pre-cut control panel holes from Ø33mm to Ø37mm. Standard switch diameter size are 32.5mm and 35.6mm.

The button can operate with voltage input between 9Vdc, ,12Vdc to 24Vdc. (Can be as low as 7Vdc).

It consist of 6 wired connections.

Pin 1 – 9-24Vdc +ve (Red)
Pin 2 – 9-24Vdc -ve (Black)
Pin 3 – Switch Output (Blue)
Pin 4 – Switch Output (Green)
Pin 5 – LED indicator + (Brown)
Pin 6 – LED indicator – (Orange)

The power consumption of the switch is very low, within only 40mA. When operating power 12Vdc to 24Vdc, the button current consumption is at 3.4mA (standby) and 26.7mA (when activated). The LED current can be from about 3mA (for 12Vdc) to about 9mA (for 24Vdc)

The following wiring diagram illustrate how you can connect this touch-free button to any existing elevator lift system. This touch-free button has a built-in mini mechanical relay to replicate a typical mechanical switch in a life system This makes it easy for this touch-free button switch to be installed with any electronic equipment or system.
