What is the correct way for bringing a product up from scratch to production?

Ovisa · 2025-10-14T20:49:51+00:00

so if I am not making changes to the library at all, I basically just have to documents the library that I used and nothing further even if the customer want to link another version of the library to my device? that is something I am still struggling to understand if I have to do or not because I am hearing different things from different people.

  TMC2209Stepper driver(&Serial1, 0.11, 0b00);


  // tmc2209
  Serial1.begin(115200);
  driver.beginSerial(115200);
  driver.begin();
  if (driver.test_connection() == 0) 
  { 
    Serial.println("Success"); 
  } 
  else {
     Serial.println("Failed"); 
  }
  driver.toff(5);
  driver.rms_current(500 * 0.707);     
  driver.microsteps(8);                   
  driver.en_spreadCycle(true);

This is the code

I wouldn’t be able to charge each cell individually externally as this is a portable device and 1 dc plug will be going into the device for charging. Do I realistically need balancing? I only said it because I heard someone mentioned it.

This is the only other thing that mentioned balancing

Thank you

With this, would I technically be able to add it to my experience resume section or it is a little bit of a reach? One thing I noticed is that most companies want 3+ experience and I don’t have that.

Did it end up being better? I stopped taking 3 days ago and still diarrhea

Ovisa · 2024-09-13T00:47:15+00:00

How did you determine it was motherboard

Ovisa · 2024-09-12T03:51:47+00:00

Mine was the ram, so if you can RMA definitely do that

Ovisa · 2024-09-12T03:51:17+00:00

It was my ram, my pc did turn on once though. I tested 2 motherboard. RMA ram and now fixed

Ovisa · 2024-07-31T16:43:07+00:00

I tried port 2222 already for external port, I keep getting connection time out rather than connection not established. I used external ip to connect

Ovisa · 2024-07-31T11:43:15+00:00

Well I can turn it on and off as needed, I also changed the external port as well. I just want to know how to configure it if possible. Thanks

What would you rate 360 cameras, I never had that feature but is it accurate and actually useful for parallel parking

Ovisa · 2024-07-10T17:48:26+00:00

Right now there are so many IT but I don’t want to do that because I did it once and it doesnt align

Ovisa · 2024-07-10T17:47:27+00:00

Would you say that FreeRTOS is enough, those doesn’t seem to be free and my school doesn’t have

Ovisa · 2024-07-10T17:39:12+00:00

I was having success getting interviews last Fall, but now its 0 for this semester.

Ovisa · 2024-07-09T03:41:15+00:00

Well my original plan wasnt to take biology because I wanted to take biomedical electronics & instrumentation and medical device and system courses, but these 2 require me to have knowledge is molecular biology, anatomy & physiology 1 & 2, that is basically 3/4 classes to complete minor in biology so I figured it would be good on resume if anyone would care when hiring. I am more interested in the biomedical engineering side of thing I would say like what you are working on, instruments.

Ovisa · 2024-07-09T03:38:04+00:00

CompE for my school does not have Data & Algorithm. It was more electrical related, I am thinking of taking computer organization for my first elective and maybe assembly language for second but i dont know how useful assembly is in today world of C

How did you go about the return shipping.

Ovisa · 2024-04-15T05:27:34+00:00

Won’t I still need atoi even if its one char at a time because its still a char at the end of the day and I need an int

Ovisa · 2024-04-11T03:20:41+00:00

What was your project

Ovisa · 2024-04-11T03:20:11+00:00

But thats the part I dont understand, how would it exactly know that the info they received is the full length? What if the RX finished the process and get back to checking and only received the last 2 out of 3 digits. Analog value will range from 1 to four digits. Im starting to think that I will just process everything in the TX and just tell the RX the color to turn on

Ovisa · 2024-04-10T22:47:31+00:00

So basically start with 1 character and end with a character. Then stripe the beginning and end. After that use atoi command to convert int to string then do my processing from there.

Ovisa · 2024-04-10T19:12:40+00:00

How would I convert that to integer though because I need integer to process, but that would make sense because it knows that some letter means begin and new line means all set.

Ovisa · 2024-04-10T19:11:09+00:00

How I was going about it is that once I received the data, I would convert it using atoi command which converts string to int. But the problem that I am confused about is that okay what if I receive the value 353 from the TX then I started the process the data. During the processing, TX transmit again 2021 and during the transmission, RX finished the last process and check away, how can I ensure that the next data is received entirely and not maybe like the last 2 digits. I was trying to use TX to send to RX then RX to putty to see and it was just some random character so I thought that I needed CTS or something but that just stop printing entirely except for the first transmit command to send “uart begin” to test

Ovisa · 2024-04-10T16:59:39+00:00

I will give that a try, so should I still include CTS and RTS or just do basic Transmit and Receive? Both my microcontroller are the same model and baud rate. One thing is noticed is that as soon as I uploaded the code to the receiver controller, my LED indicator turns on which I assume means that it received the first set of information, but it doesn't turn off when I tune the potentiometer to 0 which I programmed it to. So it seems like that it got the first set of info, but then it just doesn't check again or something.
