Convert old vending machines to cashless payment

How to convert your older pulse and legacy vending machines to accept modern cashless payment terminals via the MDB Interface?

Vending machines provide convenient 24-hour transactions for buyers as well as sellers. It is a very efficient way of distributing daily needs products. Vending is made possible with the cash coin/notes acceptor which uses pulsed output to activate the machine to dispense.

With the advancement trend in payment, more and more people are using digital cashless payment.

  • Credit Card
  • QR code payment
  • Mobile phone NFC
  • etc…

Many of these new payment modules has adopted the vending industry MDB (multi-drop bus) interface. Using MDB interface allows vending machine and its peripheral to use the same language to communicate with each other, making the entire vending system plug & play. This means that it is simple to install and integrate. No matter the vending accessories you buy, you know that it is going to be compatible work when the MDB cable is connected to your machine.

Older legacy machines that are still using the old pulsed output coin/notes acceptor will find difficulty in integrating into the modern MDB payment collecting module.

Introducing PIC-031 MDB to Pulse converter

PIC-031 MDB to Pulse converter is designed to support older legacy machines or simple machines that accept pulse input as a means to start operating. With PIC-031 converter board, your machine can now accept modern MDB based cashless payment terminals. Your legacy machine can now accept cashless payment modes like Credit Card, QR code, NFC payment from your customers.

For developer of vending or gaming machines, you do not need to understand the technical details of the MDB (Multi-Drop Bus). Simply use PIC-031 MDB to Pulse converter, and you can interface your machine to a MDB cashless device to help you collect payment.

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.

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.

reference: https://gnu-mcu-eclipse.github.io/

  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
    to drag the install button onto the Eclipse Marketplace dialog box.
    Click the <Confirm> button to install the plugin.
  4. Install “xPack GNU Arm Embedded GCC” program.
  5. Install the SEGGER J-Link
