Detailed Description

pwm related system calls

System calls for reading and writing pwm/ppm values.

Field Documentation

uint16_t(* system_calls_pwm::read_ppm)(const struct system_calls_pwm *self, uint8_t chan)

Parameters

chan	ppm channel to read

Returns: ppm value of the given channel. If channel is out of range then 0 should be returned.

uint16_t(* system_calls_pwm::read_pwm)(const struct system_calls_pwm *self, uint8_t chan)

Parameters

chan	pwm channel to read

Returns: pwm value of the given channel. If channel is out of range then 0 should be returned.

void(* system_calls_pwm::write_motor)(const struct system_calls_pwm *self, uint8_t id, uint16_t value)

Parameters

self	instance of the system calls interface
id	motor id (typically in range 0 - 7)
value	pwm value (typically in range 1000-2000 but can be slightly more or less)

Writes a motor value to a motor output with given id. If id is out of range then values should be ignored. Motor outputs are typically separate from servo outputs and run at 490hz instead of 50hz update rate.

void(* system_calls_pwm::write_servo)(const struct system_calls_pwm *self, uint8_t id, uint16_t value)

Parameters

self	instance of the system calls interface
id	servo id (typically in range 0 - 7)
value	pwm value (typically in range 1000-2000 but can be slightly more or less)

Writes a servo value to the given output. If output id is out of range then value should be ignored.
