==Auxiliary connectors interface ==
=== Description ===
The Auxiliary connectors interface available on the Evaluation Kit at the connector ''TBD:Jxxx''are J11 and J12, 2x15x2.  ''Jxx'' is a ''TBD:connector-type'' 54mm stripline header connector for the RS232 two-wires UART3 port, used for debug purposes (bootloader and operating system serial console).
On these connectors are available many interfaces, some of this peripherals are not available at the same time:
* FDCAN1
* FDCAN2
* I2C5
* SPI5
* UART7
* SAI2
* 11x8 keyboard matrix
* LED driver
* JTAG

=== Device usage ===
To connect ==== CAN ====The CAN interfaces need a tranceiver to be connected to the CAN bus. '''NOTE:''' the FDCAN1 pins are shared with touchscreen I2C interface and are not available when using I2C5. ==== I2C5 ====Configured by deafult for touchscreen I2C interface. ==== SPI5 ===='''NOTE:''' these pins are shared with UART7, cannot be used at the same time. ==== UART7 ===='''NOTE:''' these pins are shared with SPI5, cannot be used at the same time. ==== SAI2 ====''TBD'' ==== LED driver ====Open collector outputs through a 120ohm resistor. Can be drive indicators LEDs By default all the pins are available. ==== keyboard matrix ====See the debug serial port[[ETRA SOM/ETRA Hardware/Peripherals/IO expander|IO_expander]] page for more details. (''TBD'') '''NOTE:''' COLUMN[0:5] are not available by default as the pins are routed to the LED open collector outputs ==== Interface membrane ====This mambrane can be provided for user interface when the system is mounted on the 4 modules DIN BAR profile, it can offer up to 2 keys and 6 LEDs.
# connect the DB9 adapter bracket Please send an e-mail to the J22 connector on the SBCX board# connect a serial cable between DB9 connector and PC COM port through a NULL-modem cable (not provided)# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are[mailto: 115200,N,8,1helpdesk@dave.eu helpdesk@dave.eu] for more informations.
