LIN (LOCAL INTERCONNECT NETWORK) SOLUTIONS

#define SCI

#define LIN_PORT_ADD

#define LIN_RX_PINNB

Example: ST72-104/215/216/254 MCU family

#define

UART_TIMERA, UART_TIMERB or SCI

Description

Define only one of these options. Define

UART_TIMERA or UART_TIMERB if you use a mi-

crocontroller without SCI and depending on the tim-

er you want to use. The serial communication will

be emulated by software with a timer. If you use a

microcontroller with an on-chip SCI, define SCI.

The hardware SCI peripheral will be used.

#define

LIN_PORT_ADD

Description

Needs to be defined only if UART_TIMERA or

UART_TIMERB is defined.

Set which pin is the LIN RX pin. This symbol should

be set to the address of the data register of the I/O

port linked to the LIN RX pin (PC3>set address of

PCDR register).

#define

LIN_RX_PINNB

Description

Needs to be defined only if UART_TIMERA or

UART_TIMERB is defined.

Set which pin is the LIN RX pin. This symbol should

be set to the number of the pin linked to the LIN RX

pin (PC3>set 3).

LIN RX is pin:

PB0 (Port B pin 0)

PB2 (Port B pin 2)

PC0 (Port C pin 0)

PC3 (Port C pin 3)
