What does this mean?

I found this line in the default camera code, and I can't figure out what it means:

Pwm1_red ^= 1;

it sort of looks like early pascal, in which case it would just set the variable Pwm1_red to 1, but elsewhere in the code the more traditional "=" is used.

Anyone know what this means?

This expands to Pwm1_red = Pwm1_red ^ 1;

^ is the xor operator, and like other operators, can be combined with = to give the shorthand statement that confused you
