#Usb machine stm

##Overview

It's a project for stm32 f4 (we test it on stm32f4-discovery). It's implement USB device for connecting to usb machine and accept requests for setting machine coordinates.

It uses custom protocol but use USB class CDC (0x02).

##Driver

You should use WinUsb driver for proper work with usb machine app. We use Zadig for this purpose.

##Requirement

We use GNU ARM Eclipse Plugin for builds this project and OpenOCD 0.7 for loading elf file to board and for starting the board. Also, we use GNU Tools for ARM Embedded Processors's gdb for debugging.

You can find full instruction here.

##Load, start and debug

To load and to start code you should use OpenOCD tool (external tool for start eclipse project).

###Load

We use snippet below for load binary file.

-f ../scripts/interface/stlink-v2.cfg
-f ../scripts/target/stm32f4x_stlink.cfg
-c "init; reset halt"
-c "flash write_image erase usb-machine-stm.elf"
-c "reset run; shutdown"

###Start

(You must load your binary file before starting board.)

We use snippet below for start board (do it before start debugger).

-f ../scripts/interface/stlink-v2.cfg
-f ../scripts/target/stm32f4x_stlink.cfg

###Debug

After start your board, you start a debugger.

We use GDB Hardware Debugging with GNU ARM GDB with config bellow.

Remote target with Debugger options bellow.

And add custom Initialize command to Startup:

monitor reset halt
