Keyer Project Update - Almost Public

Well, I've been working on the memory keyer and it now can record and play back memories programmed through the keyboard. I can send a serial number that gets updated automatically, and I've fixed the odd bit here and there. I've confirmed it compiles through the IDE on Windows, although I'm still stymied by the IDE under Linux. I also tested to see if it really would key the FT-102. It does.

It's a Memory Keyer!

Well, I've been working on the keyer. It turns out that the Arduino Mega has the I2C bus on different pins than the Arduino Uno. Since my keyer shield doesn't actually have pins for that location on the Arduino, I had to come up with an adaptor mechanism. I bought some extra long pins from Jameco and put two of the wires into a two-pin housing, and now I have a display. The lack of sidetone output was traced to a broken wire going to the speaker. The paddle inputs didn't work, but that turned out to be a software error.

Why I'm re-writing the keyer software

It occurs to me that I never explained why I'm re-writing the keyer software. To recap the project up to this point: I have wanted a CW memory keyer for a long time, and I had wanted to do some project with the Arduino. However, I didn't think that my circuit design skills were up to designing the necessary hardware and I didn't really want to write the software, and it occurred to me that someone else might have decided to use the Arduino as the basis of a memory keyer and have designed hardware and written the software necessary to make it do what I want.
