Data Logger

Elektor has a long history when it comes to publishing data acquisition systems and loggers. The data logger proposed here is unique due to its simplicity and compact size; a microcontroller and a handful of common components are all it takes for hardware.

The Secrets of I²C

The I²C bus analyser described in this article connects to the I²C bus of an application, extracting its start, stop, address, data and acknowledge signals for the purpose of examination. It can be used to troubleshoot a reluctant proprietary circuit or to "reverse engineer" existing applications.

Real-Time Computing

By using a Real Time Operating System (RTOS) the structure of the software and the timing characteristics of the microcontroller can be significantly improved. Here we describe the operation and specific characteristics of such an RTOS.

From C to Hardware

Despite technological trends most new equipment does not take advantage of the capabilities of FPGAs. The main reason for this is that there are still relatively few FPGA experts. The latest developments in the EDA area can largely eliminate this obstacle.

ECIO PLC

A low-cost ECIO module acts as the brains of a PLC board that has relays, optoisolators, CAN (!) connectivity and an LCD. All this I/O capacity together with Flowcode allows the board to act as a versatile, powerful PLC for quite complex control and automation projects.
