I  could ptint out "Planetary Gear". This planetary gear set can moving that you spin center gear.


This set is made 6 parts.

Ditect User button, STM32f429 + uClinux.

STM32f429 Discovery board has one user button(User button is blue, black is reset), but  the button is not existing source.
Button configurations add to source ~/stm32f429-linux-builder/uclinux/arch/arm/mach-stm32/iomux.c.

You can detect user button state from STM32f429 dicovery board.

Added code:

/* PA01 = USER Button1 */ gpio_dsc.port = 0; gpio_dsc.pin  = 0; stm32f2_gpio_config(&gpio_dsc, STM32F2_GPIO_ROLE_IN);

Using example:

# echo 0 > /sys/class/gpio/export # echo in > /sys/class/gpio/gpio0/direction # cat /sys/class/gpio/gpio0/value 1 or 0  <-- Button state

LED blink STM32f429 with uClinux.

STM32f429 Discovery board has two user LED, and the they LED defined in the uClinux image. STM32f429 Discovery board pin configuration exists at ~/stm32f429-linux-builder/uclinux/arch/arm/mach-stm32/iomux.c that seek keywords 'PG13' or 'PG14' where define gpio PGx to LED configurations.

You can do blinking LEDs from console.

Before Using:

echo 109 > /sys/class/gpio/export  echo 110 > /sys/class/gpio/export

Brinking example:

#!/bin/sh echo 109 > /sys/class/gpio/export echo 110 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio109/direction echo out > /sys/class/gpio/gpio110/direction a=1 while [ $a -ne 0 ] do    if [ $a -eq 1 ]    then       a=2       echo 1 > /sys/class/gpio/gpio109/value       echo 0 > /sys/class/gpio/gpio110/value    else       a=1       echo 0 > /sys/class/gpio/gpio109/value       echo 1 > /sys/class/gpio/gpio110/value    fi    sleep 1 done

STM32f429 Discovery on ucLinux

Working the ucLinux  get on easily the STM32f429 Doscpvery board. And making image can find github and clone your PC.

For running ucLinux on the STM32f429.

1. Host computer setup.
   My host computer is VM that is made VitrualBox.
   Host OS ubuntu 14.0.4LTS install to VM.

2. Host OS setup.
   Network configure on your environments.

   "git" install and setup.

   $ sudo apt-get update
   $ sudo apt-get install git

   If your environment use proxy when setup proxy environment.
   $ export http_proxy=http://<<PROXY HOST URL>>:<<PORT>>/
   $ export ftp_proxy=http://<<PROXY HOST URL>>:<<PORT>>/
   $ export https_proxy=http://<<PROXY HOST URL>>:<<PORT>>/

3. Install and Build OpenOCD

   OpenOCD needs several packages, so you can find and install them.
   $ sudo apt-get install libtool autoconf automake texinfo
   $ sudo apt-get install libusb-dev libusb-1.0

   OpenOCD download from the github.
   $ git clone http://git.code.sf.net/p/openocd/code

   Build OpenOCD.
   $ cd code
   $ ./bootstrap
   $ ./configure --prefix=/usr/local --enable-stlink
   $ echo -e "all:\ninstall:" > doc/Makefile
   $ make
   $ sudo make install

4. Installing Toolchain.
   Down load “arm-2010q1-189-arm-uclinuxeabi-i686-pc-linux-gnu.tar.bz2”
   The file exruct, made arm-2010q1 directory. Toolchain are under bin directory. So make path.
   $ export PATH=/home/XXXX/stm32/uclinux/arm-2010q1/bin:$PATH

   In case of execute toolchain when fail commands.
   $ arm-uclinuxeabi-gcc
   bash: /home/XXXX/stm32/uclinux/arm-2010q1/bin/arm-uclinuxeabi-gcc: No such file or directory

   The toolchain commands are made by 32bit program, and need 32bit running environment.
   (My host OS is ubuntu 64bit)
   $ sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0

   If toolchain behave to below as OKAY.
   $ arm-uclinuxeabi-gcc
   arm-uclinuxeabi-gcc: no input files

5. Install romfs
   $ sudo apt-get install genromfs


6. stm32f429 linux download, build and install.
   $ git clone http://github.com/jserv/stm32f429-linux-builder
   $ make
   $ make install

7. But! I can't install!!
   Installing use STLink v2 that needs USB2.0, but VirtualBox has only USB1.0.
   VirtualBox add to USB2.0 function via extension pack.
   Latest VirtualBox version download and install, and more download extension pack. Olacle's VirtualBox here .

   And usb device is "root"
   $ make install
   libusb_open() failed with LIBUSB_ERROR_ACCESS

   $ sudo make install

If you want to change kernel or busybox configuration when need ncurses for "make menuconfig". Top level "make" using configuration files exists in ~/stm32f429-linux-builder/configs are busybox_config and  kernel_config.

Running needs environment:
   STM32F429I-Discovery board
   USB mini B(429) <---> A(PC) for ST-Link

   USB serial conversion cable, I bought that.
      Txd and Rxd line cable.
      Ex. serial connections.
         STM32 PC11 --> Cable connector Orange Txd(PC)
         STM32 PC10 --> Cable connector Yellow Rxd(PC)

   Terminal settings:
      Baud rate: 115200
      Data: 8 bit
      Parity: none
      Stop: 1 bit
      Flow control: none

# ./zork Welcome to Dungeon. This version created 11-MAR-91. You are in an open field west of a big white house with a boarded front door. There is a small mailbox here. >open mailbox Opening the mailbox reveals: A leaflet. >take leaflet. Taken. >read leaflet Welcome to Dungeon! Dungeon is a game of adventure, danger, and low cunning. In it you will explore some of the most amazing territory ever seen by mortal man. Hardened adventurers have run screaming from the terrors contained within. In Dungeon, the intrepid explorer delves into the forgotten secrets of a lost labyrinth deep in the bowels of the earth, searching for vast treasures long hidden from prying eyes, treasures guarded by fearsome monsters and diabolical traps! No DECsystem should be without one! Dungeon was created at the Programming Technology Division of the MIT Laboratory for Computer Science by Tim Anderson, Marc Blank, Bruce Daniels, and Dave Lebling. It was inspired by the Adventure game of Crowther and Woods, and the Dungeons and Dragons game of Gygax and Arneson. The original version was written in MDL (alias MUDDLE). The current version was translated from MDL into FORTRAN IV by a somewhat paranoid DEC engineer who prefers to remain anonymous, and was later translated to C. On-line information may be obtained with the commands HELP and INFO. >
