Control a servo

Once more time for a POC. Well, a lot of people have proven it works… but I just want to see it working with my own eyes: controlling a servo via Arduino. Final goal: use the servo to move parts of analog cockpit gauges (e.g. attitude indicator). A servo typically has three wires: red: power …

Button matrix

For the past weekends I started thinking about how to implement the FMS. There are two things to solve: MilViz its KA350i does not provide any external interface with the FMS. The only thing that is there is the FMS panel as part of the VC, and the FMS as 2D panel. The PL21 FMS …

Happy birthday

It took a few weeks (as each item is built on demand), but finally it has arrived: the MFG Crosswind!! Again one step closer to elevated FS realism! More information about this beauty can be found on http://mfg.simundza.com/products. First impression? Wow! Arguably the best value in rudder pedals currently available to flight sim enthusiasts outside …

Reading 12-byte number to control LEDs

Today I tried to send a 12-bit number to my Arduino board, in which each bit controls a digital output connected to a LED. Test completed. Mission accomplished! Once I have my MAX7219 IC, I will try to control 64 LEDs… which will be useful for my annunciator panel later on. /*    Test reading 12-character input from serial port.    Reads 12 characters from the serial port to control a series of leds that represent annunciator status fields of the KA350i.    The final implementation will use a MAX7219ENG (DIP) serially interfaced 8-digit LED display driver to control a 8×8 LED matrix, but the idea will be more or less the same. …

SLF4J

Up till now I outputted all required logging information via the most basic command: System.out.println(“Normal logging information”); System.err.println(“… when things go wrong information”); This is OK, but gives me little control. Therefore I took a look at the different Java libraries available and came to the conclusion that SLF4J is the one I need. Added …
