I haven’t looked into that. I took the easy route.

Is there any circuit for 3.3v to 5v level converter using transistors.

Hehe, the board doesn’t seem to very C-code-friendly I know I haven’t posted anything in a while, but it’s really nice to see people can still find their way to this information

It’s me again…

Arff the character to replace don’t display well here ( ” ) : it’s the normal double-quote open string character…

Hi there,

Bodhi, first I’ve the same error like you :
MyFrame.cpp:22: error: stray ‘\342’ in program
….

In fact it’s because you copy/paste exactly the : extern “C” { … code from this page.
Change the “ by ” and normaly it’s works directly !

Very thanks to Panic1 who wrote this page that allow me to compile this software with the K8055 board !!!

No they don’t. They can be higher if you like, but there are limits. Some of the caps need to have to same value. It’s in the datasheet somewhere, but I don’t know all the details from heart

Do the values of the capacitors matter? I haven’t been able to find .1 uF and .47uF capacitors.

The compile program can’t find your libk8055.so file. I believe you first need to do “make install” in the libk8055 directory.

I can’t get this to compile ‘make’ after editing the MyFrame.cpp file, i get …

or unedited MyFrame.cpp file, i get …

or vice versa.

Any clues? I have G++ usblib etc…..

Am I missing something here that you have installed?

Peace.

I’m glad it was of any help to you.

In part 5 I have posted a circuit board layout you can solder on an experimentation board yourself without overlapping paths, this makes it even easier
