Data Structures
struct	pios_dmashot_timer_cfg
	Configuration struct to assign a DMA channel and stream to a timer, and optionally specify a master timer to update single timer registers of timers without DMA channel. More...

struct	pios_dmashot_cfg
	Configuration struct holding all timer configurations. More...

Functions
void	PIOS_DMAShot_Init (const struct pios_dmashot_cfg *config)
	Initializes the DMAShot driver by loading the configuration. More...

void	PIOS_DMAShot_Prepare ()
	Makes sure the DMAShot driver has allocated all internal structs. More...

bool	PIOS_DMAShot_IsConfigured ()
	Checks whether DMAShot has been configured. More...

bool	PIOS_DMAShot_IsReady ()
	Checks whether DMAShot is ready for use (i.e. at least one DMA configured timer). More...

bool	PIOS_DMAShot_RegisterTimer (TIM_TypeDef *timer, uint32_t clockrate, uint32_t dshot_freq)
	Tells the DMAShot driver about a timer that needs to be set up. More...

bool	PIOS_DMAShot_RegisterServo (const struct pios_tim_channel *servo_channel)
	Tells the DMAShot driver about a servo that needs to be set up. More...

void	PIOS_DMAShot_InitializeGPIOs ()
	Initializes the GPIO on the registered servos for DMAShot operation. More...

void	PIOS_DMAShot_InitializeTimers (TIM_OCInitTypeDef *ocinit)
	Initializes and configures the registered timers for DMAShot operation. More...

void	PIOS_DMAShot_InitializeDMAs ()
	Initializes and configures the known DMA channels for DMAShot operation. More...

void	PIOS_DMAShot_Validate ()
	Validates any timer and servo registrations. More...

void	PIOS_DMAShot_WriteValue (const struct pios_tim_channel *servo_channel, uint16_t throttle)
	Sets the throttle value of a specific servo. More...

void	PIOS_DMAShot_TriggerUpdate ()
	Triggers the configured DMA channels to fire and send throttle values to the timer DMAR and optional CCRx registers. More...
