ok more work on the cnc

basic layout of the hardware has started. With the options on i want. Each axis will have controls and a menus system with 4 extra buttons for features later. etc.So I got 3 axis control so far. with digital reads for them and a control system for each axis. Which mean I am a limb short. The 5 buttons in the row over lcd are the menu control buttons. and the wires run out to limits.

shown here

but they got kicked for optical ones first thing

More Stm32f4

OK bit of a code post

First open a terminal to start up the listener so i can program the board

$ cd stlink.git/
$ sudo ./gdbserver/st-util fu bar


next to send a program to the board in a new terminal

cd ~/stlink.git/example/blink

make CONFIG_STM32F4_DISCOVERY=1

$ arm-none-eabi-gdb
(gdb) target extended localhost:4242
(gdb) load blink.elf
(gdb) continue

Control-C stops the program

and quit ends and starts the program on the board automagicly.

Now this is just with an example and using the post below to get my build environment up and running.

Had  no issues with programing or anything but when i reset - i.e unplugged the board the program was not running. Firing up the gdb and repeating these commands

$ arm-none-eabi-gdb
(gdb) target extended localhost:4242
(gdb) continue

and only one led blinks. Not the 4 in the center of the board.... More to follow as i figure this out.

yep i am stupid

Might help if i program the flash not the ram eh?


./flash/flash write path/to/file_name.bin 0x8000000

works just fine! With my ability to program the board and upload code to both the flash and the ram, I am all set not to go back to windows and have to finish deployment from there to the target boards. Next on the chopping block to is to gleam out how to do proper usb identification for my device. I.E a usb CNC Machine with Serial Communications. Which hopefully is not that hard. Seems someone has do a bit of CNC gcode converting software for stm32 already so after i figure out this usb crap i am going to have a look at that.

ok got my stm23f4 to compile code under linux and up load it to the board using the tutorial here

awesomeness

pcb mill

progress

update on the pcb mill

White boards

Updated my white board space.

I mount the new smaller boards to the wall with 3m sticky velcro, I love the fact i can pull them off the wall to write on.

and off the wall

and the backside

added cork board to the bottom so i can attach whatever to it but it had screw holders

and they are gone with it prepared to go on the wall

and the Finished look

should help a bit as it allows me to pull them off the walls to make updates etc. for 20 bucks total not a bad way to track stuff.

Cheap senors containers

I have been eyeballing those solar yard lights from Wal-Mart all summer long....

Well they finally are on clearance for 2 bucks a piece.  !!!!
So I grabbed up 3 up them for 6 bucks along with a monster.
Some quick tear down photos:

Any's you get the point They are easy to tear down and only need a phillips screw driver. End result

This will make quick work of my solar powered sensor network.
