GTATLUG talk about Atmel AVR
Greetings, Peter Hiscocks. I tried sending the following to your Ryerson email address but the message bounced so I am trying to get it to you this time via the GTALUG mailing list. I saw a video of your talk about Atmel AVR parts. Interesting talk. There are a few points you didn't make about the AVR microcontrollers. First, the instruction set is optimized for C. This is one of the reasons I chose to use AVR parts instead of PIC. That and no bank switching of memory with AVR. Second, you can use the AVR part without the need for an external crystal in many cases unless you are doing something requiring very precise timing. If you don't need precise timing you can use the built-in oscillator but it can also be calibrated to improve its timing accuracy. The real "Hello, World" program for hardware (such as microprocessors, microcontrollers, CPLDs, and FPGA's) is the blinking light. The question from the audience "Is the Atmel only on the Arduino?" was interesting. A lot of people associate the ATMEL AVR processors with Arduino when Arduino is more about the form factor and pinouts on a PCB and the software libraries, and programming method than about a given processor. You could have an Arduino board that doesn't use an ATMEL part. -- Cheers!

I regret to say that Peter died a week or so ago. He was always curious and willing to experiment with all sorts of things. I miss him already, although I hadn’t seen him for several years. ../Dave On Aug 15, 2018, 4:26 PM -0400, Kevin Cozens via talk <talk@gtalug.org>, wrote:

I'm very sorry to hear that. Peter will be greatly missed. ----------- Obituary: HISCOCKS, Peter - Passed away on August 1, 2018 at age 73. We regret to report the passing of Peter, beloved husband, father, brother, activist, and all-around excellent human being. Over the years Peter has been a founding member of the Women in Engineering Summer camp, involved with the Coalition for Gun Control, and was a driving force for the reduction of light pollution in the city of Toronto. As a professor at Ryerson university, Peter left his mark on students in electrical engineering and theater courses alike and accumulated a host of entertaining stories he was happy to share at the drop of a hat. Following his retirement, he directed some of his effort to his business, Syscomp Electronic Design, providing low-cost digital electrical instrumentation around the world. In June, he celebrated 50 years of happy marriage to his wife Dorothy while riding a train through the Rockies. Other notable trips include professor-exchanges in Brazil and China, a trip to New York with his daughter where they managed to see several planes and an aircraft carrier but not the Statue of Liberty, and a lovely series of trips with his wife to Bermuda, Eastern Europe, and Costa Rica that hopefully made up for their horrible honeymoon. Among other things, Peter was known for lending a hand, falling from high places, finding clever solutions, the school of approximate carpentry, owning too many oscilloscopes and telescopes, occasionally setting things on fire or extinguishing them, a love of trapdoors, antennas, and analog circuitry, and overall being a kind, generous, loving teddy-bear of a man. He will be deeply missed

Thanks for telling us. I first met Peter when he started a group for programmers of the Atari ST. That would have been 30 years ago. I learned a lot from conversations with him. His interests were diverse!
