A new project done by the Microelectronics Students' Group: Coilgun for Acquisition and Signal Processing.

A coilgun is a linear electric motor that accelerates a ferromagnetic projectile by attracting it to successive coils.
The goal of the project is to implement a coilgun with closed loop control powered by the XMC4500 Relax Kit.

Here is a video on the coilgun closed loop test:


Each coil is fired until the projectile passes the corresponding light sensor. At that point, the next coil is fired.

This project was done by the Microelectronics Students Group from FEUP, Portugal.


The goal was to implement an infrared proximity sensor to read the distance of a target using the XMC4500 board and DAVE3 as the development tool. Generally speaking, all we need for that is a proximity sensor, an analog-to-digital converter, some form of changing voltage to distance and a way of displaying the result. Here's a video of the finished project working:

Welcome to XMC Hands On Training on
How to do a Secured UART communication with AES?

Overview
Encryption is frequently recommended as the best way to secure business-critical data, and AES is the most widely used standard when protecting network traffic, personal data, and corporate IT infrastructures.

Hence for this training we are going to use the Advanced Encryption Standard (AES) apps found in DAVE3 to encrypt and decrypt data messages.

Beside this, the training shall also guide you on how to configure XMC UART for transmitting and receiving data with a PC (Docklight). The operating of FIFO data buffer is also featured in UART receive interrupt.

What is Advanced Encryption Standard (AES) ?

2 data messages are being encrypted and display on the PC screen.



The encrypted data are extracted and re send to XMC for decryption.

A single unidirectional TVS diode structure is designed for a wanted signal between ~0V and a “Maximum working voltage” specified for the TVS diode. In case of a negative signal is applied between signal line and GND, the device will become conductive if the signal level exceeds about minus 0.5V. Such a device can i.e. be used to protect a unipolar digital data signal. The ESD Absorption capability of the diode is granted for a positive AND a negative ESD strike.

In order to protect bipolar signals, i.e. signals providing both positive and negative voltage values, a bidirectional TVS device is needed. The V-I curve of such device is symmetrical with respect to the origin, and the ESD absorption capability is granted for a positive AND a negative ESD strike in the same way. A bidirectional TVS diode can be created by using two identical unidirectional TVS diodes connected in series or by integrating the bi-directional functionality in one die.

Tip of the Week: to learn more about bidirectional and unidirectional protection diodes and their I/V characteristics, please take a look on the Application Note AN327:

** ESD Simulation Models **

The TVS design kit aims at supporting designers used to the Agilent Advanced Design System (ADS) software for circuit design.
It contains models of ESD TVS diodes and all necessary parts to use these models.
Device models also include in-package parasitic components, such as bond wire inductances, resistances, etc.

Overview
This is a Fast charge adaptor, which is capable of supporting the QC2.0 protocol (Quick Charge 2.0) from Qualcomm with excellent charging efficiency as compared to other competitors. It make use of Infineon XMC1200 high performance 32bit Cortex M0 CPU and DP2A single stage fly back controller with power factor correction to produce maximum power output of 15W @ 9V/1.67A.

Further development to this fast charge concept will include a security hardware authentication chip from Infineon ORIGA to pair up with device such as mobile phone, tablets etc. This will have the benefits of protecting customer original products from counterfeits and unauthorized replacement parts.

Implementation
The QC2.0 (Qualcomm) protocol make use of different voltage level of the USB D+/- to request for the required charging Vbus voltage. Hence the fast 12 bit ADC of XMC1200 is required to convert the D+/D- voltage level to digital value which can then be process by the software and make the request to DP2A for the charging voltage output.

The QC2.0 software protocol embedded within XMC1200 had been tested and verified with a Quick Charge 2.0 enabled device from Qualcomm.

The software will also request the system to enter into Sleep mode when charging is completed or device is unplug to reduce power consumption. A fast wake up happens when the device is plug in to the adaptor and charging will resume at this point.

Welcome to XMC Hands On Training on
How to create a CGI and SSI web server with lwIP stack?

Overview
This hands on training consist of 2 parts

Part 1
The 1st part of the training shall guide you on how to create a web server with lwIP stack using XMC4500. The web server application consist of the Common Gateway Interface (CGI) and Service Side Include (SSI) features which allow you to interface with the web server to toggle a LED and read a ADC value respectively. The XMC4500 shall also retrieve the web page from the SD card and serve it to the client PC.

Note: Some SD card are not so lucky to be readable by the SDMMC apps, hence causing the web server to hang. We are still looking into this issue and hope to remove this message once we have a solution on this.

Part 2
The 2nd part of the training shall guide you on how to install web pages onto the XMC flash instead of reading from the SD card.



Lets see how you can make use of the CGI method to toggle a LED of the XMC4500 Hexagon board.



You can also use the SSI method to get feedback information of the ADC value from the XMC4500 to the client PC.
