You can do four things to a structure:

1.

2.

3. Take its address with &

Let’s w to use structures
with th

1. Pass components to the functions separately.


2. Pass an entire structure to the function.


3. Pass a pointer to a structure to the function.

In a moment we’ll see why #3 is best.

y = pulser1.pulseWidth // y now equals 127;

Struct

struct pwms {
struct pwm pulser1;
struct pwm pulser2;
struct pwm pulser2;
int numPulsers = 3;

and to access pulser1 pulseFreq we use:

x = myPWMS.pulser1.pulseFreq;

While it may not seem like it at this time, this kind of syntax can m
easier to write and understand, with the usually warning that C gurus will use
them to impress and thereby confuse you.

Structures and Functions

Copy it

Assign to it as a unit

Access its members

rite some functions to modulate some pulses and see how

em. We could approach this three ways:
