in UP Xtreme Windows

Hi

Setting the PWM Value without using windows.devices.pwm

Upbridge and eapi.dll have this function
EApiPwmSetValue(pin, PWMBaseint, PWMFraction, PWMDuty)

All I need to speed everything up in terms on development is the equation for converting a frequency into the PWMBaseint and PWMFraction

Can you help?

Thanks
Steven

    UP Xtreme PWM frequency is 128 ~ 16000 , PWM formula as following
    PWMBaseint = Frequency * 256 / 32000
    PWMFraction =((Frequency % 125)/125) * 16384
    PWMDuty is 0~255 levels

    Notice: not any frequency in the range is supported.
