Austin Community College - Initial Specs for FRDM-TFC line following car.

This uses the fine library by ELI HUGHES.

Our goal here is to provide the simplest line-follower as a quick car checkout.

First, we limit the run duration for the car, so that you can catch it, if necessary. Right DIP switch (4) sets run time. 0 => 5 sec, 1 => 10 sec.

We provide simple speed selection with the other three DIP switches. I recommend 001 as the slowest real speed, (000 is stop, of course). DIP switches 1 2 3 make a 3 bit speed. 1 is msb, 3 is lsb

The car won't start until you press and release the driver's side PB. Left PB (TFC_PUSH_BUTTON_1) is permissive GO on release using left 3 DIPs for speed 0-7.

The car will stop when the passenger side PB is pressed. Right PB is STOP - TFC_PUSH_BUTTON_0

TFC_Ticker[3] is our run time counter. Like the Code Warrior edition, we use msec tickers.

Left (Driver side) trim pot 1 can be used to trim static steering servo Right trim pot 0 can be used to offset line camera

Back LED reflects drive motor status. The top three are not currently used.
