Usage Information

LPUART peripheral interface.

Function Documentation

status_t lpuart_full_init ( const peripheral_descriptor_t *  self, serial_byte_receive_func_t  function  )

static

Note that we don't ungate the LPUART clock gate here. That is done only after the autobaud process has completed successfully.

void lpuart_full_shutdown ( const peripheral_descriptor_t *  self )

static

Note: if not deinit autobaud(IRQ method), user app may encounters hardfault if it doesn't provide related pin interrupt service routine.

bool lpuart_poll_for_activity ( const peripheral_descriptor_t *  self )

static

This function will be called from the main peripheral detection loop to drive the autobaud detect for this UART instance. If it is completed the UART is fully initialized and ready to use.

Variable Documentation

const peripheral_control_interface_t g_lpuartControlInterface

Initial value:

= {
    .pollForActivity = lpuart_poll_for_activity, .init = lpuart_full_init, .shutdown = lpuart_full_shutdown, .pump = 0
}
