[to be updated] When you write programs in languages like C or C++ the programs get converted by the compiler tools into commands that the computer can read and understand. Just before the compiler tools do that they convert your work into a sequence of commands into a language called Assembler. Back in the day […]
Here is an example of running a timer on the LPC804, originally written in C and then modified to work in C++14 on MCUXpresso 11.1. Here we're using the 1MHz Low Power Oscillator to drive the Wakeup Timer on the LPC804. The same code would work as a C++ project on the LPC802 (OM40000 board) […]
As part of my examination of C++ programming on microcontrollers, I've run into an issue with implementing Interrupt Service Routines on the LPC804 and LPC802 microcontrollers. These micros are based on the ARM Cortex M0+ core, are small, solderable and suitable for teaching and project development with undergraduate engineering and computer science students. I'm looking […]
Here's a simple program, written for the LPC802 or LPC804 microcontroller, using MCUXpresso 11.0, the ISO C11 compiler and the latest LPC802 (OM40000) or LPC804 (OM400001) SDK from NXP. I started a project using MCUXPresso and the SDK, then erased the contents of the main .c file it produced, replacing it with the following: The […]
While I was on sabbatical from York University I had the opportunity to teach twice at the University of Applied Sciences in Karlsruhe, Germany (Hochschule Karlsruhe, a.k.a HsKa). I had been invited to do so by Professor Klemens Gintner, a colleague and friend who I had hosted during his sabbatical in Toronto in 2015. It […]
As part of my sabbatical activities I took on the "Temps Pratiques" microcontroller laboratory sessions for electrical engineering and mechatronics students at INSA Strasbourg. In pre-sabbatical discussions with faculty and staff at INSA Strasbourg I found out that the students were learning using what I considered to be outdated technologies. The PIC16F84A microcontroller chip used […]
While on sabbatical I started getting serious about writing a book. In spite of having wanted to write a book for years, writing one while on sabbatical wasn't my primary goal. But as visa issues in France became more difficult and made more traditional research work harder the book writing became a bigger focus for […]
During my sabbatical from York University, I taught IP 411 "Embedded Systems for Engineering Applications” class at Hochschule Karlsruhe (HsKA) in April and May, 2019. This page is an update to the Fall 2018 version of the course that I also taught at HsKA. The Spring version of the course take place over six days: […]
On this page you will find the documents for the "TP" (Practical Time) lab that I instructed at the INSA Strasbourg Engineering School in Strasbourg, France while I was on sabbatical from York University. Links to videos and other material are included in the PDFs. The lab uses the Microchip Curiosity board, with built-in debugger […]
I recently updated my MPLAB X installation to version 5.10. The compiler hasn't changed, just the IDE. Two surprises occurred. First is that my SAMD board now crashes the IDE when I plug it in. Only on Windows 10 on my HP tablet. Works fine on my Mac. But I won't get into that today. […]
