Design Lab update 17/8/06
It’s worrying me. 4 weeks into the semester and the circuit has not been built yet. Graeme sort of set us the pace by asking us to play around and familiarise ourselves with the components, but I feel the time PLAYING around with the components is a bit too… scary. Anyway, we decided to understand how the components work by the end of this week, and hopefully get a circuit up and running by the end of next. We also decided to use the simplest (and most device intensive, i.e, expensive) circuit for the time being. After getting a working circuit, we could then do a major overhaul on reducing the components needed, and crack our heads on the software part. Drawback of a simple circuit: Blardy hard to write software code.
After burning two 7-segment displays, I got the displays to count up by using the PIC to control the output. We also suspect the ADC is also fried. ^_^” Well, this goes without saying since we just slapped on the voltages and the inputs without reading through the datasheet properly first. Gonna test the ADC again tomorrow. Hope it works.
Till next time.
