  1. Thanks very much for your kind attention to this. Here's some additional information that might be relevant to the product manager. I am a 65 year old retired instructor of C++ and Java Language at Ottawa's Algonquin College. I've been retired for 5 years. I've taken up a hobby in electronics, and got my HAM radio licence for Canada 3 years ago. My HAM callsign is VE3WEF and can be checked online at the QRZ site for international HAM radio users. I'm greatly enjoying this course, but would greatly benefit from checking my homework against (probable) right answers. I would only use this for personal use (as I am no longer teaching) and at home. I would not share the answers, as I understand those issues quite well. As I said I've purchased both the AD2 and the parts kit (mostly chips) for this cours. So if there's a way for me to get the homework answers that'd be great. And if not, thanks so much for trying. Best, Roland Prevost CANADA
  2. Hello All, Had an Analog Discovery 2 for maybe a year, and I've found it very useful and fun to work with. Last couple of days, I finally noticed the Real Analog course materials and they're great. So I purchased the parts kit (not yet arrived) and began to study. However, I'm now trying to find out the location of the answers to the Homework Assignments. Does anyone know if they exist, and if so, where? Great hardware and educational materials, Roland
  3. Thanks Attila, very helpful. Found it instructive to see many of the 555's pins activities at once, instead of limited to the 2 channels of the scope. Binary output, of course, but still ok. Thanks for the tip re:adding resistance to bring down voltage to spec. Makes complete sense. Merci, Rol
  4. Thanks for taking a look at this, and possibly passing it on to the creator of the software. If it is an aggregate of the signals on the bus, that would not be particularly useful with multiple inputs from a 555 chip, as I am (just for fun) doing. Pleased if you learned something new, as that might assist others as well. Best, Rol
  5. Hi John, Thanks for your quick reply, and moving my post to an appropriate section. I will check to make sure the 555 is compliant with the relevant standards. The phrase I sent you, as well as an image of the Sine Wave I mentioned, come from the HELP/instruction file that comes with the latest version of WaveForms 2015, in the Logic Analyser section. Which is what prompted my second question, in the first place. Since the "help manual" mentions it, I therefore thought it might be possible. Let me check again which section, just to make sure ... Yup, it's right there at the end of section 3 - Signal Grid, under Logic Analyser, just before section 3.1 begins. There's an image of what's called a "Sine Wave Representation" there in the trace track I believe. Thanks again, Rol
  6. Hello, Really enjoy the Analog Discovery 2! Just beginning to play with the Logic Analyser, past day or two. Just for fun, I connected five data pins to five different 555 ic chip pins, using the "signal" choice, under bus type in the Logic Analyser. Very interesting to see power go up and down all at the same time. Helps in understanding what an ic chip is doing on many pins, in real time, even if the representation is binary (on or off). HOWEVER, I believe this tool was not designed for this use, So I wanted to ask: Q1: Should I avoid using the logic analyser, with ic chips? Q2: IF I can do this safely, how might I change some of the traces I see on the screen, such that they show "Analog Sinewave" instead? The instructions do mention this, saying: "With higher row height for Bus or protocol, the analog representation of the values is drawn." Showing an image of a Sine Wave, instead of a square wave. Even though I change the height of the trace tracks to 10 higher, the views remain square waves. Any idea how I might get it to show sine waves (as per instructions) instead? Or is this not possible with a "signal" choice for trace? Thanks, Roland Prevost
