Keeping water under surveillance: Control

This thesis describes the work of two students who designed the control system of a stand-alone water well measuring system, named SubDowser. The project was done by order of a proposal from the start-up company SkyDowser. The total thesis group, consisting of three subgroups, was asked to build a working prototype which could measure the water...

Gearbox Control Unit for the Paddle-shift System: Implementation and Verification of the Hardware and Software

In the dynamic domain of motorsport, the most agile is naturally the victor. A race car can only be as efficient as the systems that control it and here lies the importance of automotive embedded systems which offer precise and quick control over the mechanics of the race car. The Gearbox Control Unit (GCU) for the Paddle-shift System is one...

Design of a controller for an adjustable frictionless resistance fitness device, with wireless user feedback

This report proposes a design for a control system for a variable frictionless resistance training device, that is able to set the resistance and give feedback to the user via a wireless connection. The fitness device uses regenerative braking and information about the generated power is sent back to the user. The variable resistance is set...

A Low Power System-on-Chip with Memory Stacked on Top of Logic

This work introduces a low-power Cortex-M0+ based computing platform for battery-powered, embedded applications. Voltage stacking is used to save power by recycling charge through a power domain between 0V and Vdd, and a power domain stacked on top of it between Vdd and 2Vdd. The technique enables connecting chips of the future directly to the...

Network-based bootloader for distributed embedded systems applications

This thesis describes the design, implementation and deployment of a network-based bootloader for distributed embedded systems applications. The bootloader is based NXP's LPC1769 microcontroller containing the ARM Cortex-M3 processor. The CAN bus is used as the network's physical layer. Due to the modular design of the bootloader, easily...

Wireless Indoor Climate Sensor: Implementing the Control Unit at Ultra Low Power

With the completion of the MIST1431 multi sensor IC a demonstrator developed by the Electronic Instrumentation Laboratory of Delft University of Technology and NXP, a demonstrator that shows the capabilities of the MIST chip was needed. This thesis describes the implementation of the control unit, which has to control the MIST chip and wireless...

Evaluation Methodology and Systematic Selection of Microcontrollers for Delfi-n3Xt Nanosatellite

90 nm VLSI Design of an 8-bits Microcontroller

Integrated Circuit (IC) design complexity has increased radically since the first "hand-made" designs in the late 50s, with a few transistors. Nowadays, Very Large Scale Integration (VLSI) designs contains hundreds thousand, million or even billion transistors and not only the experience of the designer, but also Electronic Design Automation ...

Analytical cost estimation for embedded systems

In the today's market of microcontrollers and FPGAs, there are so much different makes and models that making the right choice for a hardware platform for an electronics design is impossible. The spectrum is so wide that an electronics designer is unable to make a good choice for the best microcontroller or FPGA for his/her design based on the...
