Introduction

A wide variety of widely-available flight controllers and associated robotics boards have been released in the past five years. These boards incorporate a careful selection of sensors and actuator outputs useful for robotics-- not just for flying vehicles, but also rovers and underwater vehicles. This living document analyzes briefly the compatibility of embedded Rust with these inexpensive and powerful boards.

Overall Utility Issues

General issues that impact the usefulness of embedded Rust with these kinds of boards:

No (or fragmented) DMA support. Some embedded HAL crates have DMA support already, but many do not. Almost none of the DMA APIs resemble each other. There is at least one effort underway to unify the DMA APIs

By any means necessary, get a serial bootloader onto the D6

I had to use linux bluetoothctl tools to scan for the D6 device, get its address, use nrfutil to update via bluetooth. Look at options with nrfutil dfu ble --help to figure out how to specify device address etc.

Some of the notes from Fanoush were helpful, some were not.

I eventually installed this binary which allowed me to upload subsequent binaries using TTL-over-USB rather than BLE.

	# print demangled symbols
	set print asm-demangle on

	# set backtrace limit to not have infinite backtrace loops
	set backtrace limit 32

	# detect unhandled exceptions, hard faults and panics
	#break DefaultHandler

	Wiring instructions
	- Remove three pull-up resistors on SDA, SCL, ADO/MOSI
	- PS1 must be closed
	- PS0 must be closed (in this example we hardwire WAK always on)
