I decided to implement FeldHell mode on my Propeller based QRSS/WSPR/Opera/CW beacon. It was a bit fun figuring out the timing and the font, but here is a sample:
It is a simple 5x7 font and I draw each character from the lower left to the upper right resulting in the slight forward slant of the characters. Right now I have only defined upper case characters and numerics in the font.
I will post the complete code after I have gotten some sleep... :)
You guys are so damn clever. It takes me days of head scratching just to get a simple RC filter for PWM to DC to work properly!
ReplyDeleteI'm constantly in awe of what you Ham guys can come up with after a few hours of hacking. So impressive.
