Technical Overview
This demo uses the Propeller Port API library to control the pins of the 8-bit local Propeller Port and blink an LED. A
couple cool things about the demo is that it toggles the pins on the I/O header +- in pairs then -+, thus no matter which
way you have the LED nor what pins you have it plugged into, it will actually blink or go bi-color (if you were lucky and got
a bi-color LED in your kit). Below is the entire main() loop of the program.
void main()
{
// Always call ConfigureClock first
SYS_ConfigureClock(MAX_FCY_RATE);
// initialize SPI
SPI_Init();
// give Prop a moment before sending it commands, the boot process is about a second
// if you like you can speed it up, by removing the Prop driver's "LED blink" sequence in the driver
// or speed it up, but commands that are sent before the Prop driver is done booting will be ignored.
// therefore, if you have a lot of set up work to do, then you don't require a delay, but if you jump right
// into commands, then you need a good 1.5 - 2 second delay
DELAY_MS( 2500 );
// clear screens
NTSC_ClearScreen();
NTSC_Color(0);
// set direction of prop port so we have all bits output
PropPort_SetDir( 0b11111111 ); // 1 is output, 0 input
// enter infinite loop...
