Hello everyone
first if all, im not an expert in PWM, but doing my best to understand everything
I have successfully created and tested a project using the pwm_driver example.
nrf_drv_pwm_config_t const config0 =
{
.output_pins =
{
OUTPUT_PIN_1 | NRF_DRV_PWM_PIN_INVERTED, // channel 0
OUTPUT_PIN_2 | NRF_DRV_PWM_PIN_INVERTED, // channel 1
OUTPUT_PIN_3 | NRF_DRV_PWM_PIN_INVERTED, // channel 2
NRF_DRV_PWM_PIN_NOT_USED // channel 3
},
.irq_priority = APP_IRQ_PRIORITY_LOWEST,
.base_clock = NRF_PWM_CLK_1MHz,
.count_mode = NRF_PWM_MODE_UP,
.top_value = 100,
.load_mode = NRF_PWM_LOAD_INDIVIDUAL,
.step_mode = NRF_PWM_STEP_AUTO
};
in this piece of code, the top value is set to 100.
I understand that I have an accuracy of 0 to 100, so its actually just a percentage
Now i would like to have an accuracy of 0 to 65535 ( actually just a 16-bit integer )
I have already tried playing around with the top value but it seems to only go around 30 000.
I have been looking around and my guess is that I have to change the base_clock, but i don't really know what I'm doing at ths point.
Is this even possible to achieve? If not, whats the maximum top value then?
Thanks in advance
Maxime Mylle
