Auxiliary connectors interface[edit | edit source]

TBD: sostituire le sezioni con le informazioni sull'uso della periferica e del suo connettore Nell'esempio di seguito c'è la descrizione dell'interfaccia UART/console

Description[edit | edit source]

The Auxiliary connectors on the Evaluation Kit are J11 and J12, 2x15x2.54mm stripline header.

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[edit | edit source]

CAN[edit | edit source]

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[edit | edit source]

Configured by deafult for touchscreen I2C interface.

SPI5[edit | edit source]

NOTE: these pins are shared with UART7, cannot be used at the same time.

UART7[edit | edit source]

NOTE: these pins are shared with SPI5, cannot be used at the same time.

SAI2[edit | edit source]

TBD

LED driver[edit | edit source]

Open collector outputs through a 120ohm resistor. Can be drive indicators LEDs

By default all the pins are available.

keyboard matrix[edit | edit source]

See the 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[edit | edit source]

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.

Please send an e-mail to helpdesk@dave.eu for more informations.

JTAG[edit | edit source]

See the JTAG page for more informations.
