SEGGER’S SYSTEMVIEW ADDS DATA ACQUISITION VIA UART AND TCP/IP

SEGGER announces the release of SystemView V3.10, a major update to its system verification tool for embedded systems. The most significant enhancement is the addition of real-time data acquisition via UART or TCP/IP. Any system with UART or TCP/IP connection, typically Ethernet, can now be monitored and verified. The new version comes with the target code …

Make Raspberry Pi into a LDAP Server to Store User Account Data and Password

Introduction An LDAP server provide the following benefits: Authenticate for all the users of Raspberry Pis and computers in your network Store files stored /etc directory Store contact details that can be useful for email clients My personal reason of running an LDAP server is to have one central point of authentication. After completing this …

Reading analogue data on a Raspberry Pi using MCP3002

I got a bit disappointed with my little bus pirate yesterday. I’ll investigate how to update it to fix the odd SPI behaviour another time, but for now, its on to trying to read the MCP3002 SPI ADC chip directly using the Raspberry Pi. However, this one I’m going to do a bit differently. My …

Switch through custom data with 16×2 LCD screen and Raspberry Pi

Introduction After starting my circuit testing with some LEDs and switches I moved up to a small 16×2 LCD screen (HD44780 controller) with the Raspberry Pi. The configuration of the LCD pins and base code for output to the 16×2 LCD screen is taken from the excellent Raspberry Pi Spy website. I’ve made a few modifications: …

Read analog data, in Java Raspberry PI

mportant: This document goes along with the code at https://github.com/OlivierLD/raspberry-pi4j-samples/. In the sources, refer to ADC The goal here is to read analog data from a Java program running on a Raspberry PI. For this example, we will be using a potentiometer like this one. When the user turns the knob of the potentiometer, its …

Multichannel Professional Data Logger on Raspberry Pi – Part 1

See the Part 2 for the hardware and Part 3 for the software implementation. In this series of articles I’ll explain how to build a multichannel Data Logger, capable of collecting voltage, current and temperature measurements over the specified intervals of time. Our alternate goal is to proof that Raspberry Pi is not just a …

Raspberry Web server sending GET data to Arduino Nano driving 6 servos

This is a small project I did for a colleague who is building a 1/48 scale RC model of a Fletcher class Destroyer (yup…that makes the “model” about 8 feet long!) He asked if I could animate the 5 x MKIII 5″/38 gun turrets, complete with bearing and elevation, and also being able to individually …

Streaming Sensor Data from a ppDAQC Pi Plate Using InitialState

The Pi-PlatesppDAQC Data Acquisition and Control board is an ideal interface between sensors and a Raspberry Pi. With eight analog and eight digital inputs, up to sixteen channels of real world data can be captured by a single ppDAQC Pi-Plate. But, what can you do with that data? You can use it to control a …
