Way back on Star Trek: First Contact I started using Microengineering Labs PICBASIC PRO compiler. I used PICBASIC to write the code for the Borg suits and the spacesuit lighting in that film... That was 19 years ago, and I still use it for simple projects because it is very fast for me to develop in. Here is the very simple program to operate the lighting here:

DEFINE OSC 16		'define the clock speed so PICBASIC knows
OSCCON = $FF		'set speed to 16MHz

	ADCON1 = %00001111			'port a is all digital IO

    pwmrate con 20000			'pwm freq
    faderate con 10				'delay in PWM loop to control duration of rate change
    level   var byte

high relay				'as soon as the µC wakes up, turn on the relay to latch the power

pause 250				'let settle
    
trigger:
for count0 = 0 to 255
    gosub fetch					'read in the sine value from the lookup table   
    hpwm tape,level, pwmrate	'send to hardware PWM & fade up to full
    pause faderate
next

for count0 = 1 to 50			'with a 2.3 second nap, this keeps light on for 115 sec
    NAP 7      ;nap for 2.3 seconds
next

for count0 = 0 to 255
    gosub fetch					'read in the sine value from the lookup table
    hpwm tape, 255 - level, pwmrate	'reverse the value since we are fading down
    pause faderate + 20				'make it longer to provide notice that its shutting off
next

low relay	'this will turn off power to the board
