Implementation
Generation of PWM signal
After initializing the time constants (initTime()) and setting the port pin P02.1 as
push-pull output (IfxPort_setPinMode()), a simple PWM signal is generated by
toggling a pin with the function generate_PWM_signal().
The state of the output port pin P02.1 is toggled by calling the function
IfxPort_setPinState() with the parameters IfxPort_State_high and
IfxPort_State_low.
For changing the frequency and duty cycle of the generated PWM signal the global
parameter g_generatedPwmFreq_Hz and g_generatedDutyCycle can be modified.
Depending on the frequency and duty cycle (set to 50%), two timeout values are
calculated by software and passed to the wait() function. The two wait() function calls
are succeeding the two calls of the function IfxPort_setPinState().
The parameters and functions used for the port pin control and timing are provided by
the two iLLD headers IfxPort.h and Bsp.h.
