The SIMAVR package is for simulating AVR processors like the ATMEGA328 on the Arduino UNO. I'm looking to try to use it with VPL in courses like our computer architecture class, EECS 2021, as a way of simulating the UNO's processor in exercises involving assembler and C programming. On a Mac, we use HomeBrew. The […]
EECS 2021 Lab Kit The EECS 2021 lab requires you to have both (1) the Grove board with an ATMEGA328P chip on it (you got it as a part of the EECS 1011/21 lab kit last year), as well as (2) a Snap programmer. The Grove kit (officially called the "Grove Beginner Kit for Arduino") […]
Introduction Microchip's MPLAB X permits simulation from the command line. This is interesting from the perspective of teaching if we have automatically-graded programming assignments that take the student's program and runs it against a simulated chip in an LMS like Moodle. Background I'm interested in how we can use the MDB in MPLAB X to […]
Virtual Programming Lab is a plugin for Moodle (eClass at YorkU) that permits interactive programming assignments to be made for students. There are some really good examples at Smith College on how to set it up with Python and a few with Java and C. I've posted, on YouTube, an example of how to […]
[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 […]
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with faculty and staff at INSA Strasbourg I found out that the students were learning using what I considered to be outdated technologies.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 […]
After a few months twiddling PIC16 bits in simulation I need to get three, three-hour lab sessions written up for the PIC16F84. The school has provided me with two versions of their PIC16F84A boards, one designed for Mechatronics students and one for EE students. The board designs date to the dawn of the Arduino era […]
Introduction Here we're going to "kick the tires" on examining a simple example program, using three 8-bit microcontrollers: the classic PIC16F84A, it's updated cousin found on the Microchip Curiosity Board, the PIC16F1619, and the ATMEGA328P made famous by the Arduino UNO. We'll be using a "debugging first" approach to programming that is intended to enable students […]
How bad and outdated is Assembler? For many of us, Assembler is the Latin of programming languages. Below, I talk about my changing perspective on this. In preparation for the embedded systems course I'll be helping to teach at the INSA in Strasbourg I'm reviewing my PIC-based teaching material, mostly based on the PIC32. This […]
