It is difficult to say what's wrong from your assembly code, but have you somewhere in your code after asking for data from slave, you provide clock so that slave can transmit data back? Master in I2C always provides clock. I also suggest have a look at...
That's the way to activate an output. However, hardware is important too. Disconnect solenoids and see if the line raises. If it works and when you connect soldenoid, it stops working, then you need to look for the issue in your hardware. I also assumed your solenoids are not stepper motor coils!
Rhode and Schwarz has an application note called "Db or not DB?": https://www.rohde-schwarz.com/en/applications/db-or-not-db-application-note_56280-15534.html
The math is very simply explained.
They also have a calculator (software) for download.
Not really! But if you are this much encouraged to start CCNA, that worth to buy a copy.
About Pcket Tracer, please know that you may not be able to do some excercises as it is not really an emulator to the switches and routers.
Then when you faced with such a problem, don't worry. Actually, the...
The Cisco exam is like other exams, but know that you really need to have enough information and understanding to be certified.
Cisco press books (here for your case, ICND1 and ICND2 by Wndell Odom) are generally self study books that are good to be supported by a teacher.
About CCNA routing...
There are lots of posts in this regard, but to summarize, Cisco as the main hardware device manufacturer that makes connectivity devices for Internet, stablished training cources and the related certifications.
Cisco pyramid shows that you can enter as an asociate, develop to professional and...
Re: CCNA VS MCSE
Perhaps this post seems to be a bit late, but better to write than the opposite!
Cisco as the main provider of the devices (hardware) for networking and connectivity in the world, made some cources from CCxA for beginners uo to CCxE for the real experts. Cisco focuses on the...
PIC32 is a very complete MCU, but you have another opportunity and that is PIC24 family that supports USB and USB OTG.
USB OTG means your MCU can operate as master or slave of USB. There is also a free to download version of C30 which is the C compiler for PIC24 and seperated USB libraries that...
There are good "Applicatioon notes" in Microchip site about SPI.
For now forget USB if your BT module supports SPI. For USB you need to know lots of things.
SPI is a serial communication protocol, mostly used between microcontrollers and other very specific modules such as memories.

My friend,
I'm sure about 452. It does not have the peripheral to connect to USB port directly and if you want to connect it you need some other intermediate module.
As far as I have no idea about your BT module, I assume that it may be connected to the microcontroller using serial port or SPI...
Re: smart antenna
Based on your question I spend less than 5 minutes in google and I found lots of things.
Do it! You will find your way through.
Mahdi.
452 do not have internal USB controller, so you need to use either FT232 or change Microcontroller to something else, let say 18F4552.
What kind of problem you have to program your devices?
Mahdi.
