|
|
* WARNING: backlight pwm is disabled by default because it generates a
|
|
* continuous tone in the speaker and headphones.
|
|
*
|
|
* This issue cannot be solved in any way because it derives from how the
|
|
* MD-UV380 mcu pins are used: to have a noiseless backlight pwm, the control
|
|
* pin has to be connected to a mcu pin having between its alternate functions
|
|
* an output compare channel of one of the timers. With this configuration, the
|
|
* pwm signal can completely generated in hardware and its frequency can be well
|
|
* above 22kHz, which is the upper limit for human ears.
|
|
*
|
|
* In the MD-UV380 radio, display backlight is connected to PD8, which is not
|
|
* connected to any of the available output compare channels. Thus, the pwm
|
|
* signal generation is managed inside the TIM11 ISR by toggling the backlight
|
|
* pin and its frequency has to be low (~250Hz) to not put too much overehad on
|
|
* the processor due to timer ISR triggering at an high rate.
