Re: #2 Tilt Sensor [Post Homework Here]

[1] What is the purpose of the two balls inside of the tilt sensor? The balls inside the tilt sensor close the circuit between the two wires when gravity pushes them down to their resting position. [2] Why can the tilt sensor we are using also double as a vibration sensor? When the balls are not be...

Re: #2 Tilt Sensor [Post Homework Here]

Hi just a general question about tilt sensors.. how do they differ from accelerometer ? Most projects seem to use a combination of an accelerometer for slow tilt measurements, and then a gyroscope for fast vibrations capture. Any ideas why/how that's done? It is popular to combine accelerometer dat...

Re: #1 The Introduction [Post Homework Here]

[1] Why are you taking this course? I am taking this course because I want to learn how to build my own devices using sensors to detect what's going on in the surrounding area. [2] What do you hope to do with the knowledge you gain through this course? I want to build a trip-wire sensor so I know w...

Re: 4-bit Shift Register in VHDL

Hi Pyro, Thank you for your quick response. I took a look at those link but i'm not familiar with test bench simulation. I'll dive into that these days. On the other hand, what i've found, was an interesting code that i could understand in some book about digital electronics. This is the code: ... ...

Re: 4-bit Shift Register in VHDL

Hi, Is there a way to code and simulate a 4-bit shift register with components from this Course? Thanks, Milos Hi Milos, I don't believe we have a shift register example in this course and we didn't cover test benches for simulation either. However, there's a lot of good resources out on the web. H...

Re: #7 Doesn't work for some unidentified reason

Hey PyroElectro First of all i would like to thank you for your quick and detailed response. I appreciate it very much. You were right from the beginning. The problem (at least part of it) was in hardware wiring. I’ve fixed those two issues that you pointed out but unfortunately that was not the en...

Re: #7 Doesn't work for some unidentified reason

Hi, I've written good VHDL code and edited pins in Pin Planner as you have, and i've also placed all wires and parts on the breadboard (I've doubled checked) and everything went smoothly until i programmed the chip on the board. Nothing happens: counter doesn't work, button and led also... This is ...

Re: An Introduction To VHDL

Hi, This seemed the most appropriate place for this question. I'm new here, and was just looking at the An Introduction To VHDL. On the software page, it mentions a zip file that can be downloaded at the right. I can see the corresponding file link in the Verilog intro, but can't see a download lin...

Re: how to interface adc with fpga

Sounds like you need to write a VHDL or Verilog module that conforms to the SPI or I2C standard of your device in order to clock the data out of it.
