I bought the Adafruit Metro M0 Express because it has both a debugger port soldered on and has a SAMD21 chip on it. While it has a bootloader and CircuitPython on it, I'm actually only interested in using it as a potentially student-friendly development platform for learning C / C++ on the Cortex M0+. I […]
While testing out the PIC16F88 replacement for the PIC16F84 on the INSA microcontroller teaching board I ran into issues with two things not working as per the standard sources of examples (e.g. Microchip's Developer Wiki): Interrupt Service Routines Bit setting, clearing via structures These examples appear to have been written for versions of XC8 prior […]
I'll be teaching the IP 411 "Embedded Systems for Engineering Applications” class at HS Karlsruhe in October as part of my sabbatical activities. It will take place over four days: Fri 12 October 2018, 2 pm – 5.30 pm Sat 13 October 2018, 9 am – 5.30 pm Fri 19 October 2018, 2 pm – 5.30 […]
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 […]
While planning a book on programming microcontrollers I've been trying to settle on a small group of microcontrollers that could be used for examples. Every couple of years I do this to myself. Below are a few examples, including the ubiquitous Arduino UNO with an 8-bit chip, as well as the FRDM-KL25Z and Adafruit Metro […]
