Re: 3D Parametric Function Plotting

I have already sent an email to the author benedek, but I want to post it publicly as well. Enabling screen overscan settings in "/boot/configure.txt" causes a black screen when the program in question is invoked. Restarting, disabling overscan settings, then running the program again with the same ...

Re: Why were so many pins dedicated to power & gnd

There apparently are claimed technical reasons for the multiple grounds (but what about the reasoning for 3v3 & 5v more than one place....) Again, in different words, having multiple power pins allows for more current than one single pin could handle. Lower resistance. If you look at the pinout of ...

Re: Why were so many pins dedicated to power & gnd

The systems IO is fast enough that termination and signal propagation needs to be cared for. Having lots of ground wires between pins helps with crosstalk as well as gives engineers a way to easily realize a characteristic impedance for making transmission lines. From what I have seen, the GPIOs can...

What is the news for GLUTES on the Pi?

Hi Trying to build a project on the Pi that uses GLUT as it's OpenGL interface, and I can't find a working port of GLUTES for the Pi anywhere, but it looks like some people are close. I even saw a note or two that looked like https://github.com/damiannz/glutes only needs a few line changes to the ma...
