int LPUART_RTOS_Init | ( | lpuart_rtos_handle_t * | handle, |
lpuart_handle_t * | t_handle, | ||
const struct rtos_lpuart_config * | cfg | ||
) |
handle | The RTOS LPUART handle, the pointer to allocated space for RTOS context. |
lpuart_t_handle | The pointer to allocated space where to store transactional layer internal state. |
cfg | The pointer to the parameters required to configure the LPUART after initialization. |
int LPUART_RTOS_Deinit | ( | lpuart_rtos_handle_t * | handle | ) |
This function deinitializes the LPUART modulem, set all register value to reset value and releases the resources.
handle | The RTOS LPUART handle. |
int LPUART_RTOS_Send | ( | lpuart_rtos_handle_t * | handle, |
const uint8_t * | buffer, | ||
uint32_t | length | ||
) |
This function sends data. It is synchronous API. If the HW buffer is full, the task is in the blocked state.
handle | The RTOS LPUART handle. |
buffer | The pointer to buffer to send. |
length | The number of bytes to send. |
int LPUART_RTOS_Receive | ( | lpuart_rtos_handle_t * | handle, |
uint8_t * | buffer, | ||
uint32_t | length, | ||
size_t * | received | ||
) |
It is synchronous API.
This function receives data from LPUART. If any data is immediately available it will be returned imidiately and the number of bytes received.
handle | The RTOS LPUART handle. |
buffer | The pointer to buffer where to write received data. |
length | The number of bytes to receive. |
received | The pointer to variable of size_t where the number of received data will be filled. |
