C++ on microcontrollers 4 – input pins, and decoding a rotary switch

Wouter van Ooijen November 12, 20112 comments

previous parts: 1, 2, 3

 This blog series is about the use of C++ for modern microcontrollers. My plan is to show the gradual development of a basic I/O library. I will introduce the object-oriented C++ features that are used step by step, to provide a gentle yet practical introduction into C++ for C programmers.  Reader input is very much appreciated, you might even steer me in the direction you find most interesting.

So far I...

Handling latency in data acquisition systems

Fabien Le Mentec November 8, 2015

In recent projects, I found myself working with data acquisition systems. For instance: PCIe/10GbE readouts for 2D XRay detectors (RASHPA slides, RASHPA paper) instruments mixing 1D signal acquisition and triggering, microcontroller based system for audio transmission: (NRF spearker)


Working with Microchip PIC 8-bit GPIO

Luther Stanton April 24, 20241 comment

The third in a series of five posts looks at GPIO with PIC 8-bit microcontrollers. After a detailed review of the registers for configuring and managing GPIO on the PIC18F47Q10 processor, a basic application is stood up programming those registers to blink external LEDs at 0.5Hz.


STM32 B-CAMS-OMV Walkthrough

Peter McLaughlin April 30, 20231 comment

The STM32 B-CAMS-OMV camera module offers an accessible way to get started with embedded vision. Coupled with the STM32H747I-DISCO discovery kit and the FP-AI-VISION1 function pack, it's possible to be up and running in minutes.

This video describes the camera connection interface to the discovery kit and the key software functions required to control the camera and process its data. We review the ISP (Image Signal Processor) interface with examples of image processing...
