If an invalid signal handle is passed into the function, does nothing.
| sss | The signal handle of the signal to write. See l_signal_handle. |
| v | The value of the signal to be set. |

| void l_bytes_rd | ( | l_signal_handle | sss, |
| l_u8 | start_byte, | ||
| l_u8 | count, | ||
| l_u8 * | pData, | ||
| const mtb_stc_lin_context_t * | context | ||
| ) |
Reads and returns the current values of the selected bytes in the signal.
The sum of the "start" and "count" parameters must never be greater than the length of the byte array. Note that when the sum of "start" and "count" is greater than the length of the signal byte array then an accidental data is read.
If an invalid signal handle is passed into the function, no action is done. Assume that a byte array is 8 bytes long, numbered 0 to 7. Reading bytes from 2 to 6 from user selected array requires start to be 2 (skipping byte 0 and 1) and count to be 5. In this case byte 2 is written to user_selected_array[0] and all consecutive bytes are written into user_selected_array in ascending order.
| sss | The signal handle of the signal to read. See l_signal_handle. |
| start_byte | The first byte to read from. |
| count | The number of bytes to read. |
| pData | The pointer to the array, in which the data read from the signal is stored. |
| context | The pointer to the context structure mtb_stc_lin_context_t allocated by the user. This structure is used during LIN Slave operation for internal configuration and data retention. The user must not modify anything in this structure. |
| void l_bytes_wr | ( | l_signal_handle | sss, |
| l_u8 | start_byte, | ||
| l_u8 | count, | ||
| const l_u8 *const | pData, | ||
| const mtb_stc_lin_context_t * | context | ||
| ) |
Writes the current value of the selected bytes to the signal specified by the name "sss".
The sum of "start" and "count" must never be greater than the length of the byte array, although the device driver may choose not to enforce this in runtime. Note that when the sum of "start" and "count" is greater than the length of the signal byte array then an accidental memory area is to be affected.
If an invalid signal handle is passed into the function, no action is done. Assume that a byte array signal is 8 bytes long, numbered 0 to 7. Writing byte 3 and 4 of this array requires "start" to be 3 (skipping byte 0, 1 and 2) and "count" to be 2. In this case byte 3 of the byte array signal is written from user_selected_array[0] and byte 4 is written from user_selected_array[1].
| sss | The signal handle of the signal to write. See l_signal_handle. |
| start_byte | The first byte to write to. |
| count | The number of bytes to write. |
| pData | The pointer to the array, in which the data to transmit to LIN master is located. |
| context | The pointer to the context structure mtb_stc_lin_context_t allocated by the user. This structure is used during LIN Slave operation for internal configuration and data retention. The user must not modify anything in this structure. |
