Hard Summer Project!!
What have I got into? Hahaha Basically I have to build instrumentation to sense position and signal of a train tachometer sensor and display position and speed on LCD. The problem is I have almost none background on eletronics but I am willing to learn the maximum I can and I hope you could help!
Here are the specifications:
Below please find the spec of the tachometer interface box,
speed calculation position calculation relative & abs
seven segment LED to display position (comedy size)
position display on LCD
serial interface in/out to PC using FTDI lead
isolated zero volt output for channel A/B (operate up to 30 V, check)
three LEDS to indicate speed units (m/s, km/h, mph)
push button to reset relative distance
input/output immune up to maximum rating 60V
supply for the tachometer 12V (check)
switch for the supply
ERROR detection for QA/QB
Maximum speed of train 50 km/h
For the project I have to choose the PIC, which I am left into darkness. And also I have to read some backgrounds in quadrature encoders, signal conditioning, pic programming(change notification interrupt and input capture module, etc).
I really wanna learn about it and also make a good project( and impression) and that's why I'm gathering as much help as I can!
Any questions please ask!
