With last month’s experiment I found out that my DSLR does not stick to the advertised 30 frames per second. So I had to investigate this quite a little bit further.
In order to determine what is going on I implemented a flexible sweep generator. Although the experiment seems to require a frequency counter it does not. The point is that the desired frequency is set through the serial interface, thus anyone with an Arduino and a bunch of LEDs can verify the outcome.
The implementation exhibits some cool features that are interesting in other contexts as well. These are:
- A stream parser for numeric values
- The TRICK17 macro
I am pretty sure that my TRICK17 macro will give rise to some pointed comments 😉
And I am also sure that my parser will serve as a nice template for others 🙂
