Hello I am developing based on FREERTOS using RZ/A2M.
I need PWM function for magnetic buzzer and lcd BACKLIGHT unit.
so I am proceeding according to the procedure of GPT driver guide document.
In Document suggest 3 step.
1. setting in smart configurator.
2. open driver
3. contol command : CTL_GPT_PWM_SAW_START_CHANNEL
But PWM waveform not generate.
below my code:
s_gpt_handle = open(DEVICE_INDENTIFIER "gpt_pwm_saw4", O_RDWR);
gpt_err=control(s_gpt_handle, CTL_GPT_PWM_SAW_START_CHANNEL, NULL);
how can I get solution
