bip

I am trying to convert an ADC bipolar differential signal in C++. The device I am using is a 12 bit MAX11613 (datasheet) and the microcontroller is a Raspberry PI 3B+. So far I am able to capture values, however the results are not the differential result of AIN0 and AIN1 I would expect.

The device is a 3.3V supply and the input on AIN0 is 0-3.3V. The input on AIN1 is the virtual ground of the incoming signal at 1.65V.

The bipolar transfer function of the device shown below may be my source of confusion. Why is it that a value just under the midrange of 1.65V would produce a value of 0b111111111111 and not 0b100000000001? And if that is actually correct, how does one adjust for that to reflect an actual negative voltage compared to the virtual ground input (AIN1)?

For what it's worth, here's my code:

max11613.h

I'm trying to implement the Bitcoin specification BIP-39, specifically the part Generating the mnemonic. The following causes some headaches:

Next, these concatenated bits are split into groups of 11 bits, each encoding a number from 0-2047, serving as an index into a wordlist. Finally, we convert these numbers into words and use the joined words as a mnemonic sentence.

Splitting a binary number into groups of 11 bits. But how would I do this efficiently in Crystal?

Here is what I do, I personally find it a bit embarrassing but admittedly it works:

so I am currently working on a new programming language tr-lang

and I am currently in the process of writing the parser of the language

this piece of code is where the bug lies

I'm brand new to App Script, so please forgive my ignorance.

The Google sheet I use to hold student data is so long and unwieldy (50+ columns) that I decided to create another sheet to act as a front-end for data entry. Through hours of tutorial videos + bumbling trial and error, I've come up with a working script that takes values from my data entry form-like sheet ('Students') and passes those values to the first empty row in my destination/container sheet ('Master').

I'm really pleased with how the script working - except for the fact that it is ridiculously slow. Based on what I've read, I think I'm making too many calls to the Sheets API, and I need to figure out how to pass all the values from 'Students' to 'Master' en masse rather than one-by-one, but I don't have the skills to do that, and I can't seem to find an example.

I'm sure there's a really simple, elegant solution. Can anyone help?

Here's a little piece of my code (hopefully it's enough to see the inefficient strategy I'm using):

I have a multi-line string and need to append at the beginning of each row a (varying) character (1 white-space as separator). How can I do that with regex? Is there a way to do that without without too many splittings and merging?

It is assumed that the amount of rows is equal to the amount of characters to be added.

Input

I'm re-using a standalone Swing-based Java class which backs up and restores mysql databases.

I've tested running it from a Windows batch file (.bat) on my dev system, and it works there.

But, if I run the batch file on a different Windows , I get a "main class not found" exception.

However, when I run the command directly on the command line, it works.

The command in the batch file to run it is:

I'm trying to run the following R code:

I have this text file in which there are certain products, each with the stores in which they are available. Store lines start with tab characters, product lines do not.

To be able to visualize it in a better way, I want to order it as a dictionary, having as a key the name of the store followed by a list of the products. An example is:

I'm trying to make a string that will write itself letter by letter until completing the sentence, and the speed of appearing each letter is based on an input that varies from 1 to 10. At the end of the string, it will blink for 5 seconds until that an alien will appear. My idea was to create a setInterval to add the letters and when the counter added the array size it would return the final animation of the loop with the new setInterval call, and before it was called again it had already been cleared, and called again in a recursion by setTimout callback to maintain the infinite loop. But it's not reaching setTimout, why?
