What is the useful life of an esp32 or esp8266 using the led matrix #17

Hello, I know that calculating the useful life of something is very difficult, however I would like to ask you what is the maximum time you have used this library with usp32 or esp8266, I want to make my matrix to show text and animations all day practically, so I do not know if this library will force or quickly wear out the memory of an esp, and end up melting quickly, I know that many factors such as electrical and manufacturing influence, but let's say that the components and circuit are excellent, how long could this matrix last working, especially the esp.

I use my ShiftRegisterLEDMatrixLib code in my own "LED art". I run it continuously. The only stability issues I have experienced has been with the power supply used, not the code I am running.

Concerning "wear out the memory" on a ESP MCU, that concern only exists for writing to the flash memory, not the RAM. This code doesn't in itself write to flash.

It's great, I was worried that the esp would melt in a couple days, I had that doubt because of what was between this super library and the ws2812, the latter being more expensive in my area, I will use a good power supply, of how many volts and amps you are using. On the other hand, this library slows down to perform other tasks, takes up a lot of cpu time or I can use sensors normally. You can lower the pwn levels to eliminate load to the cpu, I need to define the colors manually so I use the color definitions in the loop mediate serial or potentiometers, it is the same to show 256 pwm values ​​than to show 8 values ​​in terms of load or work From the esp, I don't really need millions of colors, with about 100 colors it would be more than enough for me.

Thanks a lot for everything, kind regards.
