This blog post aims to describe how to setup a fully functional nRF51 development environment using Eclipse and the GCC toolchain. We are using a Segger JLink GDB server for the debugging portion, but there are OpenOCD plugins which should work (provided that it supports SWD). The Nordic application note nAN-29 describes the setup usingRead more
Lorris Toolbox is an open source application for working with embedded systems and micro-controllers which was developed by Vojtěch Boček in the Czech Republic. This toolbox of tools has a feature packed packet analyzer tool which makes analyzing and interpreting packets simple. Both Wireshark and Microsoft’s Message Analyzer can also capture packets over the network and USB traffic,Read more
Controller Area Network (CAN) is a communication protocol that utilizes differential pair communication for reliability and noise reduction, and has a fixed bit arrangement so that each packet can contain the maximum of 8 bytes. The physical protocol of the CAN bus is designed so that if there are non-conflicting IDs, one is guaranteed toRead more
We recently received a Red Pitaya, a successfully funded kickstarter campaign for open source instrumentation. The Red Pitaya has a Dual core ARM Cortex A9+ FPGA with 4GB of ram, with the circuitry to handle fast analog inputs, analog outputs, and digital GPIO. It is similar to the Parallella in that it shares the sameRead more
