Detailed Description

Structure describes configuration of lowest HDLC level Initialize this structure by 0 before passing to hdlc_ll_init() function.

Member Data Documentation

void* hdlc_ll_init_t::buf

Buffer to be used by hdlc level to receive data to.

Use hdlc_ll_get_buf_size() to calculate minimum buffer size.

hdlc_crc_t hdlc_ll_init_t::crc_type

crc field type to use on hdlc level.

If HDLC_CRC_DEFAULT is passed, crc type will be selected automatically (depending on library configuration), but HDLC_CRC_16 has higher priority.

on_frame_cb_t hdlc_ll_init_t::on_frame_read

User-defined callback, which is called when new packet arrives from hw channel.

The context of this callback is context, where hdlc_ll_run_rx() is called from.

Parameters

user_data	user-defined data
data	pointer to received data
len	size of received data in bytes

on_tx_frame_cb_t hdlc_ll_init_t::on_frame_send

User-defined callback, which is called when the packet is sent to TX channel.

The context of this callback is context, where hdlc_ll_run_tx() is called from.
