Member Enumeration Documentation

enum modm::Spi::DataMode : uint8_t

inheritedstrong

Spi Data Mode, Mode0 is the most common mode.

Enum Values	Documentation
Mode0	clock normal, sample on rising edge
Mode1	clock normal, sample on falling edge
Mode2	clock inverted, sample on falling edge
Mode3	clock inverted, sample on rising edge

Member Function Documentation

static void modm::PeripheralDriver::acknowledgeInterruptFlag ( )

inheritedstatic

Acknowledge an interrupt flag.

We use acknowledge here, since it describes the intention rather than the actual implementation.

template<uint64_t available, uint64_t requested, percent_t tolerance>

static void modm::PeripheralDriver::assertBaudrateInTolerance ( )

inheritedinlinestatic

Since baudrates are usually generated by prescaling a system clock, only several distinct values can be generated. This method checks if the user requested baudrate is within error tolerance of the system achievable baudrate.

template<class... Signals>

static void modm::SpiMaster::connect ( )

inheritedstatic

Connect GPIOs to the peripheral and configure them.

This configures the Sck, Mosi and Miso signals and connects them.

Template Parameters

Signals One Scl and one Mosi signal are required (one Miso signal is optional) and can be passed out-of-order.

static modm::ResumableResult<void> modm::SpiMaster::transfer	(	const uint8_t *	tx,
		uint8_t *	rx,
		std::size_t	length
	)

inheritedstatic

Set the data buffers and length with options and starts a non-blocking transfer. This may be hardware accelerated (DMA or Interrupt), but not guaranteed.

Warning: You must ensure that only one driver is accessing this resumable function by using acquire(ctx) and release(ctx).

Parameters

[in]	tx	pointer to transmit buffer, set to `nullptr` to send dummy bytes
[out]	rx	pointer to receive buffer, set to `nullptr` to discard received bytes
	length	number of bytes to be shifted out
