  • Description

    This is the Lisa/M you know and love but with improved processing power provided by an STM32-F4 processor with a floating point unit enabling faster computation and hugely improved control and estimation capability for your vehicles.

    Note that this variant does not include any IMU -- an external IMU must be used!

    Paparazzi Compatibility Notes:

    The Lisa/M-F4 is FULLY compatible with paparazzi flight software and uses the same software setup as a lisa_mx in the airframe file.

    The specific airframe file tag is <target name="ap" board="lisa_mx_2.0">

    F4 Advantages
    • 168MHz CPU speed, 1MB flash and 192kb RAM
    • FPU (fast floating point computations)
    • configurable DMA streams (more peripherals can use DMA)
    • multiplexed IO pins (peripherals can be mapped to various IO pins)
    • CPU usage only about 5% with standard rotorcraft flight configuration

    Bootloader Details

    Instructions on flashing via USB with DFU-UTIL

    The STM32F4 can be flashed via SWD/JTAG (e.g. with the Black Magic Probe) or via DFU-UTIL
    Luftboot currently supports only F1xx chips, so you will not be able to use the integrated micro-USB connector to flash the autopilot via Luftboot.

    Lisa/M Autopilot v2.0

    With a footprint of only 24mm by 40mm, the Lisa/M autopilot is one of the smallest in its class, yet incorporates almost everything you need to build full-featured autonomous UAVs. It is compatible with the Paparazzi UAV project software.

    In brief, the STM32 features 3 USARTS, 2 SPI, 2 I2C, 1 CAN, a plethora of timers, ADCs and a generic DMA able to serve all of them.

    Lisa/M v2.0 includes 8 servo outputs and 3 UART serial interfaces. A number of the communication interfaces are level-shifted with user-selectable voltage to allow interfacing with all kinds of peripherals, for example:

    • GPS
    • Infrared (IR) horizon sensors
    • Hobby (PWM), MK-compatible (I2C), and CAN-bus brushless motor controllers
    • One or two 2.4GHz Spektrum® DSM2-compatible remote-control satellite receivers
    Note that this variant does not include any IMU -- an external IMU must be used!

    Programming

    Lisa/M with F4 can be programmed in the following ways:

    • The JTAG connector allows in-circuit debugging of your software. To program using the JTAG connector we recommend using the  Black Magic Probe Mini.
