USB ports

USB ports

The two USB ports on the flylead MIB are always ON and can’t be controlled from the software.

If you need a switchable USB port, use one of the 4 ports on the SIB.

Software usage

CAN

The CAN bus is available as can0 network interface. Use any CAN aware tools like can-utils to interact on the bus.

GPIOs

Two gpios are available to toggle buttons. They can be controlled with:

laam laacli button reset on
laam laacli button reset off

The available GPIOs are:

  • DUT_RST: reset button

  • DUT_PWR: power button

IΒ²C

The header provides 2 IΒ²C:

  • I2C_SIB_3V3_SCL and I2C_SIB_3V3_SDA at 3v3

  • I2C_MIB_VIO_SCL and I2C_MIB_VIO_SDA at MIB_VIO reference voltage (from 0V to 5V).

Optocouplers

Two optocouplers are available to toggle on and off virtual buttons. The buttons can be controlled with:

laam laacli button 1 on
laam laacli button 1 off

The available optocouplers are:

  • DUT_OPTO_1C and DUT_OPTO_1E: virtual button 1

  • DUT_OPTO_2C and DUT_OPTO_2E: virtual button 2

Power rails

Each power rail is available via screw terminal and can be controlled by laam:

laam laacli power 12v on
laam laacli power 12v off
laam laacli power 12v reset

The MIB provides access to the 4 power rails: 1v8, 3v3, 5v and 12v.

Delivered power

The power rail maximum power are listed in this table:

Power rails power

The instant power consumption of each power rail is monitored and can be queried by laam:

laam laacli watt 12v
laam laacli watt 3v3

Serials

The header provides 3 set of serials:

  • SIB_UART1 as /dev/ttycmx0: DUT serial with hardware flow control

  • SIB_UART3 as /dev/ttycmx2: LAA serial

  • SIB_UART4 as /dev/ttycmx3: DUT serial

SIB_UART4 is also available via laam or telnet:

laam serials connect ttymxc3
telnet localhost 2000

SPI

The header provides one SPI: DDT_CS, DDT_SCK, DDT_MISO and DDT_MISO.
