I just got back my 7 segment LED circuit boards from Pad2Pad, and hooked one up, and connected it to my HC08 for testing. The way this works is that the processor only needs to drive 4 lines: data, shift, load into display and reset. My test software program runs a 16-bit counter (of which [...]
To my fuzzy little brain, the core of a ‘view’ object, be it an NSView, a JComponent, or a HWND object is simple: it’s a rectangular piece of screen real estate. It can draw into its piece of screen real estate. It gets called when it needs to be redrawn and when it is optionally [...]
I have my WWDC ticket! Wahoo!
I figured a steampunk calculator would be made using a number of modules that are handcrafted from smaller components–so I just designed a circuit board which can drive 3 7-segment LEDs using a shift register circuit, and ordered 12 of the circuit boards from Pad2Pad. They’re 1.5 inches wide by 2.5 inches tall, and hold [...]
