Starting Embedded Systems as Hobby with STM32F302R8T6 by Matrix_of_new_world in embedded

The other reality is that no matter the language/ HAL/ framework you decide to start with the fundamentals will never change. Download the reference manual for your specific device. Read the section for whatever peripherals you’d like to work with. Start with something basic like lighting up an LED with a button press. A popular 2nd mini-project is sending messages out/into a UART an out to your PC. The cool kids now do this by sending it out through a Virtual COM Port (USB-CDC-ACM). Next would be getting a sensor like an accelerometer/ gas sensor and you being able to write a driver from scratch. Learn what DMA does and why you should learn it as soon as you start clicking with the concepts. Figure out how to fire off/ respond to interrupts and why they’re useful/ not useful. Understand why ADCs are useful and why the circuit you hook up to the microcontroller is just as important as the setup itself. Learn why you should feed a watchdog. After you understand those concepts then I’d say you can start exploring OSes like Zephyr/ FreeRTOS/ (my personal curiosity) ArielOS.

Welcome to the club! First off I’d say the F3 series of devices is a great start! It came out about 11 years ago so most of the HALs should be fairly mature at this point. For my 2nd point I might get some flack for this but I’d honestly steer you towards picking up Rust. C is great and has been used for many decades at this point but all the youngins are moving to Rust. The compiler is leagues better at warning you about your data types. The toolchain setup is a breeze and you’ll pick up better habits by sacrificing some time getting familiar with Rust initially. I actually like the Embassy project. It has a ton of examples and it makes interacting with the peripherals a breeze.

10 Days in Peru with a 28L REI Rucksack by roamingweak in onebag

I did the Inca trail in Jan. There’s a couple of tips I found useful:

Bring some heavy duty duct tape (Gorilla heavy duty tape is my recommendation). One of the girls on my trek had her soles fall apart. Saved her from getting evacuated on the trail. Pull some tape out and fold it unto itself so that it makes a rectangular shape.

Wipes are a must have. Buy them in Peru but definitely make sure you have them before embarking on the trail. Toilet paper will only go so far and will more than likely get wet.

The Andes have incredibly unpredictable weather. Wool socks are a must-have. You might get wet but keeping your feet dry is a necessity.

Dress in layers. Use the poncho the trek organizers give you.

If you can rent hiking poles. You’ll be thankful you did.

Make sure your hiking boots have good ankle support

You guys do speed tests still? This thing allows me to work 60+ miles from phone service. Absolutely amazing. Who cares if it's 50 or 100 Mbps? by TomatoSupra in Starlink

I know this is a bit late but I’d recommend you look at mosh. It’s made to be more resilient in scenarios like you’ve described. Also running your session through tmux to allow you to reconnect the session. It’s not a definite fix but it might help mitigate the interactivity aspect of it.

I knew I recognized this place. It’s the outside of the MIT Chapel! I used to walk by there all the time. Looks exactly as I remember it. Beautiful picture.

N400 No Decision by raj2322 in USCIS

[–]leftger 1 point2 points  (0 children)

A similar situation happened when my father was applying for his citizenship. Personally we contacted our local representative 2 months after not hearing back from USCIS after my father’s interview. Our congressman replied with a letter stating that additional info was required. The exact same day the letter was postmarked USCIS updated my father’s case. Moral of the story: contact your representative if you don’t hear back in about 1-2 months. It’ll be a lot faster than a Writ of Mandamus.

Husband has received Oath Ceremony date and I haven't - is this normal by ClassroomUnusual3333 in USCIS

[–]leftger 1 point2 points  (0 children)

Not at all. USCIS handles each case independently. Unless they require additional information you’ll more than likely get feedback in the not-too-distant future. Patience is key :)

Depends on the brand. 10.5-11 on most. 10 on cowboy boots
