Simple Communication Interface (UART)#

sl_simple_com_init#

void sl_simple_com_init (void)

Simple Comm Init.

sl_simple_com_step#

void sl_simple_com_step (void)

Step function (used in CPC mode)

sl_simple_com_transmit#

void sl_simple_com_transmit (uint32_t len, const uint8_t *data)

Transmit function

sl_simple_com_transmit_cb#

void sl_simple_com_transmit_cb (sl_status_t status)

Transmit completed callback

sl_simple_com_receive#

void sl_simple_com_receive (void)

Receive function (used in UART mode)

sl_simple_com_receive_cb#

void sl_simple_com_receive_cb (sl_status_t status, uint32_t len, uint8_t *data)

Receive completed callback

sl_simple_com_os_task_init#

void sl_simple_com_os_task_init (void)

OS initialization function - if the OS is present

sl_simple_com_os_task_proceed#

void sl_simple_com_os_task_proceed (void)

Function to trigger the OS task to proceed - if the OS is present

sl_simple_com_robust_pack_data#

size_t sl_simple_com_robust_pack_data (uint8_t *packed_data_ptr, const uint8_t *data, uint16_t len)

Pack data between preamble byte and (if turned on) CRC checksum This function adds a 3 byte header containing preamble byte, payload length, CRC flag and CRC value to the header. If CRC is required an 8 bit CRC value will be calculated for the payload and added to the end of packet.

Returns

• the size of packed data

sl_simple_com_robust_unpack_data#

sl_simple_com_robust_result_t sl_simple_com_robust_unpack_data (uint8_t *data, size_t len)

Unpack packets from byte stream looking for valid headers. This function searches valid headers and extracts payload after the header into destination buffer. Header is validated by 4 bit header CRC and payload can be also validated by optional CRC check.

Returns

• the result of the action
