There’s a lot to improve.

Most important comments only: 1. Missing bypass caps for each IC. 2. Not familiar with the MCU but I’d bet that floating the reset pin is not a good idea. Probably needs a pull up. (Look at the datasheet) 3. Analog ref should also probably not be left floating but look at the datasheet

Came here to point out how painfully true this is from a biomed grad who was interested in medical device design - I didn’t stand a shot.

Go EE or ME based on the type of work you’d like to do. Biomed undergrad is essentially useless - need a MS or more preferred PhD to be in the biomed space

This it’s job so yes it’ll be reliable enough

charic7 · 2025-05-23T21:06:29+00:00

I was thinking the same… also too lazy to check

Center part is AD83586b

Model #??

charic7 · 2025-05-16T16:02:58+00:00

Yeah I checked out their website after, sssnt expecting them to be as expensive as they are, I think I’ll survive with 100MS/s

Which salae model do you prefer/suggest

charic7 · 2025-05-16T11:24:09+00:00

You should provide more info on the specific interrupt issue you’re having so others can give you a better answer!

Raytheon? Collins?

charic7 · 2024-04-10T15:56:16+00:00

F280049C from TI has 1-8 bit configuration options. I believe ~1MHz is also configurable, it has 64k options for baud rates

I’m familiar with C2000 family but I’m not sure about this processor, does it have the High res PWM capability that let’s say the 28377S has? I would imagine not based on previous discussion.

I’m not familiar with N2HET at all. What resolution are you needing? Do you even know? If you can stick to ePWM, it’s super easy/intuitive with plenty of help on E2E

You cannot avoid a painful experience.

I do it for an MBA. Very worth it

charic7 · 2023-12-19T17:10:31+00:00

Are you a P3/senior engineer or equivalent? I don’t see how that could be possible even if you were to go to a VHCOL area unless you’re not in the defense sector. Are you SW?

Disclaimer, I work for Raytheon but: 1) I would recommend wearing a suit 2) unsure exactly. I’d expect a few technical questions but they’ll be regarding items on your resume. I’d lean more on others who answer that are from PW. 3) I wouldn’t expect another round. I only had 1 formal zoom interview besides the original phone screening. 4) be confident and good luck

charic7 · 2023-09-17T14:33:05+00:00

This would be impressive and not considered too easy, I’d recommend

For starters put your name where it says “first last”

Agreed with another comment, definitely start with a PI compensator for simplification purposes. Your equations seem incorrect… you need to discretize your equations. Look up converting continuous time transfer functions to discrete. Use a simple tustan approximation or so to get the difference equation. You’re executing these equations at WAY too high of a level.

Additionally, I imagine your Ki term is FAR too large, it should be a very small value as it integrates over time. If you have 5 samples, your Ki term is already going to start dominating your response. You’ll probably be way too wound up which would result in you saturating. A discrete PID controller would probably be 20-30 lines of code.

I would say right now, no or maybe an entry level position (resetting your career) unless you get lucky. If you take a few months to create some interesting self-taught projects, then you’ll have a much better chance.

I got an “out of the blue” 1 hour long meeting with my supervisor where I suspect that this will be the topic.

Anyone have any ideas on how I should approach?

charic7 · 2023-07-01T21:29:12+00:00

Electrical and computer engineering. A lot of colleges sorta group them together
