PWM on output

Hi,

I'm interest too to have the rpm info in a pwm output to be able to check the current rpm in a external device,

Thanks if somebody can help

Hi,

no news on that features ?

Thanks

In this project is used  PPM port as  output for serwo control

Thanks Jarek,

but currently in the code i'ts cheese or desert. I mean even pwm input(to command vesc) or pwm output (to commande a servo).

I would like to conserve pwm input and add a erpm output on another IO.

Regards,

does anybody could help to configure simple servo output on AUX instead of servo

I put this in servo_simple.c:servo_simple_init(void)

#ifdef SERVO_SIMPLE_USE_AUX_PIN
    palSetPadMode(AUX_GPIO, AUX_PIN, PAL_MODE_ALTERNATE(HW_ICU_GPIO_AF) |
            PAL_STM32_OSPEED_HIGHEST | PAL_STM32_PUDR_FLOATING);
#else
    palSetPadMode(HW_ICU_GPIO, HW_ICU_PIN, PAL_MODE_ALTERNATE(HW_ICU_GPIO_AF) |
            PAL_STM32_OSPEED_HIGHEST | PAL_STM32_PUDR_FLOATING);
#endif //SERVO_SIMPLE_USE_AUX_PIN

commands_printf("Servo Output Initialized\n");

I put this in hw_75_300.h to disable any call to AUX_ON() or AUX OFF()

#define AUX_GPIO                GPIOC //external led, original was GPIOC
#define AUX_PIN                    12 //external led, original was 12
#ifdef SERVO_SIMPLE_USE_AUX_PIN
#define AUX_ON()
#define AUX_OFF()
#else
#define AUX_ON()                palSetPad(AUX_GPIO, AUX_PIN)
#define AUX_OFF()                palClearPad(AUX_GPIO, AUX_PIN)
#endif //SERVO_SIMPLE_USE_AUX_PIN

I can read "Servo Output Initialized" in terminal put no output on AUX_PIN !!!!
