px4flow_bsp

Rust no_std embedded hal board support package for the PX4FLOW optical flow sensor hardware.

Status

Work in progress

• Does not overwrite default PX4FLOW bootloader
• Simple blinky example
• Support for spi2 (gyro)
• Support for i2c1 (offboard i2c communication)
• Support for i2c2 (MT9V034 configuration port)
• Support for UART serial comms
• Support for DMA with DMCI camera interface (waiting on stm32f4xx-hal support)

Notes

• The only supported mode for debugging is RTT with the rttdebug feature. This is because the PX4FLOW v2.3 only makes the SWD interface available (no easy ITM solution).
• This has been tested with the CUAV PX4FLOW v2.3. On this particular board, the SWD and SWCLK pads noted on the bottom of the board appear to be swapped
