can I create my own PI card?

Sun Sep 15, 2019 10:16 am

Hello ,
Wanted to know
I have an application that run on PI - but the cpu is around 75% all the time
because it's a big apllication and we have try to reduce - nothing.

and all the code is java +python according to the pi pins (reading I\Os, using pi packages etc..)
so is there a way to build my own card ,sp it will be like PI3 but much stronger? better CPU and RAM?

Thanks ,

Highly unlikely unless you can afford to pay for several thousand units. If your application is not Pi specific there are plenty of other boards you could use.

Use a compiled language instead of Java and Python.

There already is one. It's called the Pi4: https://www.raspberrypi.org/products/ra ... 4-model-b/

And that would help as well...

lots of pop-ups...and where is that annoying music coming from?

Pi4? More speed, more ram.

I agrre with this
Use a compiled language instead of Java and Python
but we found that there are some application work better and easier to write\debug\work sometime in Java and sometime in Python.

and the application use many of the PI pins , we prefere to stay with this .


I will try the PI4

Thanks ,

That is, trivially obviously, your choice. The reason for the suggestion to use a compiled language is that you were asking how to reduce CPU load. Clearly, reduced CPU load is not a priority for your project. Or--at least--not a higher priority than using the languages you've chosen.

I'm maybe missing something here?

Your CPU is running at 75%, what's the problem?

If Python is important to your application why not make use of Cython?
