4.4. I2C EEPROM
The board has been tested with an Atmel
4.5.LIN INTERFACE
The board has been tested with an Philips TJA1020TD device (Not supplied).
The device should be connected to P71 and P72 using 0R links on R29 and R31. Alternative connections are available; refer to section 5.3 for more information.
The links R41, R45 and R47 need to be carefully considered before fitting. Damage to the device, board or connected equipment may occur if these links are fitted inappropriately. Please review the specifications for the LIN transceiver and LIN Interface before fitting any of these links.
4.6. LEDS
The EDK has three red LEDs. The function of each LED is clearly marked on the silk screen of the PCB. Please refer to the board layout diagram for position information (Section 3).
When the board is connected to a power source the Power (PWR) led will illuminate.
There are two LEDs dedicated for user control these are marked USR1 and USR2. Each LED will illuminate when the port pin is in a logical low state.
The user LEDs are connected to the following ports:
LED | Port | Microcontroller | Pin Functions on |
Identifier | Pin | Pin | Port Pin |
USR1 | P64 | 37 | FTIOA1 |
USR2 | P65 | 38 | FTIOB1 |
