Description

Make software that will show the time with binary numbers with the same LED layout as shown in the image. There are two serial to parallel chips (74HC595) driving the first 5 columns of LEDs, the last column (right most column) is connected directly to uC's PB1-PB4 ports.

The time will set by two (hours minutes) 3-bit grey code rotery encoders attached to pins on the uC of your choice.

This project should take an hour for most half an hour if you're skilled.

I love programming for AVR's, they have the nicest instruction set of all the microcontrollers I've worked on. I can't read the schematic file either after trying a couple programs, but I should be able to figure things out with a screen shot. My bid does not include any code for debouncing the rotary switches (though this may not be a problem). I also presume that your schematic either includes a crystal (less accurate) or some sort of comparitor to let the microcontroller read the 60Hz power signal if it's plugged in to the wall (more accurate) because the internal oscillator will not be good enough for a clock. After running it through the simulator, we'll need to test my code on the real board. I could either e-mail the hex file to you or you could send me a sample board to work with. Despite my best efforts, I won't guarentee that it will work perfectly the first time unless can test it myself.
