No. Redundant code could make your page slower, and that in turn might negatively affect your rankings. However, the effect of the amount of HTML on pagespeed is small. Google's John Mueller has stated on Reddit that it makes absolutely no sense at all for SEO. It was never a thing.
You can calculate this ratio by looking at how much text is displayed on your page versus the HTML code (headings, links, JavaScript, images, etc.) displaying it. Free SiteGuru trial Run a full SEO audit on your website
A cleaner, compact code and higher ratio of plain content make it easier for search engines to crawl and index a website. Keep in mind that a better text to HTML ratio won't have a massive effect on your rankings.
The stepper2.stop() line in the ISR performs floating point arithmetic, and could be a likely cause of error on the ESP32 as your search indicated.
Fundamentally an ISR should be as short and as quick as possible; ideally just setting a flag that you then poll in your main code.
I'm not familiar with the ESP, so can't really help, but it is rarely useful to post random snippets of code - they often raise more questions than answers. Either post all your code, or a minimal compilable version that exhibits the fault.

They're all being divided or multiplied by fractions. The frustrating thing is that the math works absolutely fine when I define the main arrays (blockWinds, blockStrafe, blockArea) in the setup - but when I'm using the nextion screen code that takes the data from the screen or saved files and puts them into the arrays, suddenly that those functions don't work (it's something that works separately and populates the arrays just fine - and still does, as far as I can see..).
In the nicest possible way: you have written rather a lot of code for a beginner and it is not as shiny as it could be. This is one of those cases where it would have been helpful to ask the forum questions early on in the project and get feedback (maybe you did? I didn't check your post history).
As it is, your code is opaque and appears to be poorly structured (I get that you have combined two modules). Lots of repetitive stuff looks like it could be done more simply, but it is a struggle just to figure out what it's all about.
A major mistake was going down the multi-threaded route. Parallel programming is really difficult, even for advanced programmers; so many hidden pitfalls and traps. I would absolutely not recommend it for the inexperienced.
I'm just looking for the issues with the variables now, I made an edit before to say that - multithreading isn't the issue anymore, just the fact that the variable math is churning out zeros suddenly when it worked outside of the screen code. If you want I can post both of the functional sketches separately, but I doubt you're wanting to look at them.
I've already addressed that part of the issue, I made an edit before that you might not have seen. I'm just using a single core now and still having issues at the same point due to the variable math filling my arrays with zeros where they worked fine before combining the codes.
I don't think gfvalvo is pointing out a specific error he has found; rather just making clear that you must only write in memory that you have correctly allocated. So, writing in g[0] to g[99] is fine. Writing in g[100] is an error. The error may cause a problem immediately in the next line or two of code, or it may cause an error 10000 lines of code later. The behaviour is undefined and must be avoided to begin with.
Sorry about the edit, I did leave the full code posted below it - I just figured people were reading that and not that the issue had changed. I'd have opened a new thread if I thought this wasn't going to go on as long as it has
If you would like to write data into a new Text file from your spreadsheet, you can tweak the prior VBA macro code to loop through a range of cells and Print the cell data to the file.
The following VBA macro code reads through each line of a designated text file and writes the entire line to a cell in your spreadsheet (you determine the starting point with the variable StartCell).
The following VBA macro code reads through each line of a designated text file and writes the entire line to an array variable name LineArray. You can reference any line by writing the row number you are targeting and subtracting 1 (since array values start at 0 instead of 1).
The ads.txt Guru API allows you to control your account programmatically, this enables you to manage your domains, groups and ads.txt records using your own code, and most importantly enables you to streamline publisher aquisition by integrating the domain invite process into your publisher control panel.
HTTPS connections are used with either GET or POST parameters (HTTP connections are not permitted). These HTTPS connections are made to different URIs depending on the API function required, all of which must include the API protocol version. The API response is by default provided in JSON format, however the response can optionally be provided in PHP serialize() format, and optionally encoded using base64 encoding.
As an side from your question. Instead of just calling open, you can use a command with, and when you leave that block of code, the file is closed. As it is now, if you have an error somewhere between your open and close command, you can be kicked out from your program while you file remains open in memory with no way to close that instance. So toss out your close command, and use with.
If CONFIG_ESP_PANIC_HANDLER_IRAM is disabled (disabled by default), the panic handler code is placed in flash memory, not IRAM. This means that if ESP-IDF crashes while flash cache is disabled, the panic handler will automatically re-enable flash cache before running GDB Stub or Core Dump. This adds some minor risk, if the flash cache status is also corrupted during the crash.
If this option is enabled, the panic handler code (including required UART functions) is placed in IRAM, and hence will decrease the usable memory space in SRAM. But this may be necessary to debug some complex issues with crashes while flash cache is disabled (for example, when writing to SPI flash) or when flash cache is corrupted when an exception is triggered.
The RTC watchdog is used in the startup code to keep track of execution time and it also helps to prevent a lock-up caused by an unstable power source. It is enabled by default (see CONFIG_BOOTLOADER_WDT_ENABLE). If the execution time is exceeded, the RTC watchdog will restart the system. In this case, the ROM bootloader will print a message with the RTC Watchdog Timeout reason for the reboot.
In C++ code, exiting from a non-void function without returning a value is considered to be an undefined behavior. When optimizations are enabled, the compiler will often omit the epilogue in such functions. This most often results in an IllegalInstruction exception. By default, ESP-IDF build system enables -Werror=return-type which means that missing return statements are treated as compile time errors. However if the application project disables compiler warnings, this issue might go undetected and the IllegalInstruction exception will occur at run time.
Usually, this means an attempt to call a function pointer, which does not point to valid code. PC (Program Counter) register can be used as an indicator: it will be zero or will contain a garbage value (not 0x4xxxxxxx).
In some situations, ESP-IDF will temporarily disable access to external SPI Flash and SPI RAM via caches. For example, this happens when spi_flash APIs are used to read/write/erase/mmap regions of SPI Flash. In these situations, tasks are suspended, and interrupt handlers not registered with ESP_INTR_FLAG_IRAM are disabled. Make sure that any interrupt handlers registered with this flag have all the code and data in IRAM/DRAM. Refer to the SPI flash API documentation for more details.
When enabling UBSAN for code which uses the SOC hardware register header files (soc/xxx_reg.h), it is recommended to disable shift-base sanitizer using -fno-sanitize=shift-base option. This is due to the fact that ESP-IDF register header files currently contain patterns which cause false positives for this specific sanitizer option.
Enabling UBSAN results in significant increase of code and data size. Most applications, except for the trivial ones, will not fit into the available RAM of the microcontroller when UBSAN is enabled for the whole application. Therefore it is recommended that UBSAN is instead enabled for specific components under test.
A common problem in software development is accidentally or unintentionally merging code with bugs, defects, or security vulnerabilities into your main branch. Finding and mitigating these faulty lines of code deployed to the production environment can cause severe outages in running applications and can cost unnecessary time and effort to fix.
In the following sections, we walk you through configuring the CodeCommit repository and creating a pull request and approval rule. We then run the workflow to test the code, review recommendations and make appropriate changes, and run the workflow again to confirm that the code is ready to be merged.
Before we get started, we create an AWS Cloud9 development environment, which we use to check in the Python code for this solution. The sample Python code for the exercise is available at the link. Download the .py files to a local folder.
Next, copy and paste the following code in your Program.cs file. This code will create a SQLite connection, add tables, Insert rows, and, finally, read data from the tables and display in console. Make sure to copy the code exactly as written, otherwise it may not work.
