USB Serial Port giving junk data
Yes I am asking you to check with an Oscilloscope are you getting right bits at the end of the trace which is connecting to USBtoSerial IC just hook up TX line and check what you are getting. Because that's the same data that is being printed over the screen. Junk data not necessarily means proper cRead more

Because that’s the same data that is being printed over the screen.
See lessJunk data not necessarily means proper connection there “might” be something which is causing this data corruption(if you are saying that the baud rate is correct)
Is it possible to share the circuit diagram?or layout?
USB Serial Port giving junk data
Check TX and RX pins properly. Device getting recognised just means that D+ and D- pins are working and IC is working. That's good but if you are receiving junk data it's related to TX and RX line this has nothing to do with USB side. So try to debug that.

Stepper motor stuck issue
Hey Thanks for Posting can you give more information like where it's stopping is ot same every time?and what driver u r using to run the motor?

Hey follow these steps-
1.Clear your fundamentals
I would suggest start with learning about electronics in deep basics once you have proper understanding start building stuff.
Have your basics EXTERMLY clear.
Use spice softwares to simulate circuits.
Ex-LTspice,TINA,MultiSim,Everycircuit,Proteus
2.Choose a Platform
There are plenty of platforms…..EasyEDA is online tool you can look into that or KiCAD it’s most popular open-source software and it have an amazing community.
If your company or college have access to paid services then Altium and OrCAD are amazing options
master ATLEAST ONE SOFTWARE.
3.Learn basics about EMC/EMI learn how to use tools like VNAs, Spectrum Analysers and Oscilloscope.
Learn about advance terms used in board designing and how at RF level things behave.
I would suggest focusing on learning more about circuits and how they behave at board level how different frequencies can interact with other components nearby.
In the end I have noticed new learners focus more on learning the software which is cool but it won’t pay you in long term….i have seen people with 3+ years experience in PCB designing and still designing shitty(from EMC POV) but Aesthetic PCBs .
Focus on understanding everything what’s happening in your board at frequency level.
Even a slight change in rise time can make your PCB fail every EMC tests out there.
So Focus on learning.
Follow people like Eric Bogatin,Rick Hartley Etc watch their lectures they are one of the best out there.
Happy Learning:)
