Round Touch Button Switch

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.

Our engineer can support you for your installation.

Setting up Eclipse for ARMS Cortex development work

The reason I am doing this page is because I find development work using SEGGER IDE is really painful. It is really not a fun IDE to work with. Maybe in future, it will be better. But for now, I have a project to do, and I cannot spending time on a lousy development environment, knowing how fast it would be using a good IDE platform.

It is fortunate enough that a kind soul had developed a “GNU ARM Eclipse plugin” for development of ARMS firmware, currently supprted and maintain by Liviu Ionescu. While SEGGER does not support this plugin, it is recommended by them for developer who refer to use a better development environment for their programming.
https://www.segger.com/products/debug-probes/j-link/technology/ides/eclipse/

The only disadvantage is that the developer would not be able to use the SEGGER debugging function. Being a developer, I seldom find the need to use a debugger, nor I understand how important a hardware debugger is. I don’t find it very useful so far, and managed to turn out many projects without using it. Perhaps there is a better purpose of using a debugger that I did not understand.

This is my attempt to setup Eclipse IDE for ARM Cortex firmware development work. I hope this works as it can increase my productivity tremendously. I really have a lot of blocks using SEGGER IDE, after working with many better other IDE products.

Setting Up Eclipse IDE for ARM Cortex Microcontroller development work.

  1. Download and install the Eclipse IDE. (for C/C++ Developers)
  2. Open the Eclipse program, go to the menu Help -> Eclipse Marketplace…
  3. Search for “GNU MCU Eclipse” plugin, or go to this page
    https://marketplace.eclipse.org/content/gnu-arm-eclipse
    to drag the install button onto the Eclipse Marketplace dialog box.
    Click the <Confirm> button to install the plugin.

Guide to Nordic Bluetooth BLE for Beginner

This guide provide a certain direction to learn and understand about Bluetooth BLE using Nordic tools and microcontroller.

The learning process with Nordic product can be very overwhelming. This guide provide a means to understand Bluetooth progressively.

  1. Read the book “Inside Bluetooth low energy” by Naresh Gupta
    This book contains all the technical names of Bluetooth. It is important to know that these names exist. You do not need to read this book in detail for a start. Just a brief read-through of the features available in BLE. You will need to be aware of the wording convention used in Bluetooth Low Energy. Just be aware of the terminology used in the book as it is very helpful when you navigate with the following tools and working with the source-code in nRF SDK. This book can act as a dictionary for you to understand what those terms mean.
    Another book is “Getting Started with Bluetooth Low Energy: Tools And Techniques For Low-Power Networking” by Kevin Townsend. The content is more relevant to Nordic microcontroller chip product.
  2. Play with nRF Connect apps “Bluetooth Low Energy” using the nRF52840-Dongle
  3. A short introduction and familiarisation to nRF52840-DK board.
  4. Learning how Bluetooth connects.
  5. (Optional) Play radio test with RSSI Viewer, with the application example “Radio Test Example”
  6. Watch video of how Nordic works, and what is Nordic SoftDevices (Bluetooth stack from Nordic)
    https://www.youtube.com/watch?v=tZjlixQPO-Q
  7. Start with nRF SDK (blinky application)
    Learning how Bluetooth connects.

    Application: ble_central -> ble_app_blinky_c
    Application: ble_peripheral-> ble_app_blinky
  8. Reference about the Cortex M4 C++ programming and the Nordic API for Bluetooth programming.
