waveforms | explorable explanation about the peculiar magic | Animation library

As you can see in the code below, I have a machine state with a state called start. This state should take the value of coord_x_reg , increment it by one and assign it to the output port using the assign instruction at the end. The problems are:

1. The output coord_x does not change in the simulation as you can see in the photo
   I imagine that the problem is that I cannot write and read from the register at the same time. How can I achieve the effect I want then? (I also tried using coord_x_reg as a integer variable)

2. When using reset, I have to comment some signals, other way I get Illegal left hand side of nonblocking assignment error.

I'm struggling to debug a NextJS API that is working in development (via localhost) but is silently failing in production.

Below, the two console.log statements are not returning, so I suspect that the textToSpeech call is not executing correctly, potentially in time?

I'm not sure how to rectify, happy to debug as directed to resolve this!

I followed the MMIO Peripherals page from the Chipyard documentation to learn about adding modules to rocket-chip within Chipyard framework - and all that seems to have worked pretty well. I summed up my experiences and tried to write it in a slower pace on the pages of the Chisel Learning Journey <== adding that only if the person answering question may want to take a look and see that I've got everything working correctly. In other words, I added the MMIO with in the example package of Chipyard and it compiles, generates simulator, responds properly to toy benchmark I devised, I even see the corresponding waveforms in gtkwave.

Now, the next step I would like to take is to separate this dummy design (it literally just reads from a memory mapped register that holds a hardcoded value) from the chipyard/rocket-chip infrastructure in the sense that it is housed in a separate repo, that will become a submodule of my chipyard. So, to do that, I've started from this page and took all the steps as given there:

1. a new repo was created, called it my-chip
2. into the my-chip I added build.sbt of the following content:

I'm trying to use a WebGL shader to visualize some audio data. I have an array of number which represent a normalized .wav file:

In this learning app, I've followed and excellent tutorial from Hacking with Swift on generating a wave-like animation. I've modified this app further adding some functionalities:

• Providing Start/Stop mechanism for the wave animation
• Perpetually generating random numbers for the duration of the animation
• Modifying animation if an "interesting" number is found. Initially, I've implemented logic that defines even numbers as interesting but that could be easily changes to flag prime numbers, etc.

After stopping the animation does not "run" again. This is demonstrated in the gif below.

After stopping the animation does not restart.

I'm currently trying to implement an up/down counter in Verilog with dataflow modeling. While trying to add a limit to the counter (so that the counter will reset to the appropriate value when the limit is reached) I stumbled into an error. Even though the waveforms of clear_q, clear, and clear_s are the same, likewise the waveforms of preset_q, preset, and preset_s are the same, the behaviors of Q, R, and S are different, notably Q is different from R and S.

Picture of Waveforms

Of note, the rising edge of the three clear signals is not aligned with the falling edge of the clock, however, Q going from 0 to F is aligned with the rising edge of the three clear signals.

From the code, it is clear that the only difference between clear_q and clear_s, and preset_q and preset_s, is the simple inclusion of "& 1'b1". The only way that Q would go to F from 0 is if preset_q goes low and clear_q goes high momentarily, however from the waveform preset_q stays high.

The purpose of the "& 1'b1" is to temporarily simulate the equality checker commented out.

What exactly is wrong with the "& 1'b1" or is there another issue at hand?

limited_ud_counter.v

I need to render moving audio waveform like iOS voice memo app. Here I maintain waveform:[Int] rms amplitude of waves. Now when new waves come add it in waveform[Int] and I add new UIBezierPath line at right of CAShapeLayer and translate whole CAShapeLayer by 5 points.

But translation animation is not so smooth. Could you please suggest any better approach for it?

My current implementation:

When I change the theme from light mode to dark mode the spinner text isn't visible by default or when a value is selected. I tried setting the text color to android:textColor="?android:textColorPrimary" but that didn't work. I've also tried setting text color to black but result is still the same. The app works perfectly fine in light mode.

Here are some screenshots : Spinner in dark mode:

Spinner in light mode

When I select any option "Sin" or "Cos" form the spinner, the spinner value gets selected in code but the text is not visible, it remains empty white space.

Here is my xml code for the activity :
