lab1.c

该程序源码是基于dsPIC单片机的无刷电机驱动程序。

/*
Lab1.c is the first lab in 865 SNS.  It is a simple lab to
show how to program and run the BLDC MC board firmware using 
dsPIC2010.  
The program blinks Led D1 at a 1 hz rate.  
Steps:  
1. Complile the Lab using Project -> Build All
2. If there are no errors, Close DIP switches then ..
3. Program device using Debugger -> Program
4. If there are no errors during programming then ..,
5. Open DIP swithes and Run using Debugger -> Run
6. The Led, D1 should blink at a 1 Hz rate.
