    3-axis stepper driver

    Nice job! Ive been thinking about the same thing.

    How are you going about the G-code translator? I was talking to friend about trying to do just that.

    I think being able to control more Fets with the extra I/O would be awesome.

    Dont let it get you down blue the forum is awesome and I think it has been a great success!

    10000 + registered is proof of that.

     

    If they want to see and or download files for an awesome project bad enough they will register,

    it only takes a minute even if they are a 1 timer.

     

    Maybe after a year or so the inactive accounts should go away.

    just a thought.

    Keep up the good work.

    I was on the standard issue vicodin for a few days following the surgery, Now Im just doin alleve when needed.

    Still having a fair amount of residual pain in my lower leg and ankle, but nothing like prior to surgery.

    I would not wish that on my worst enemy! The doc offered some other scripts but Im not much of a pill taker.

    Im optimistic that it will all be gone in time.

     

    heres to a speedy recovery to ya!

     

    beers!

    Welcome back!

     

    If it makes you feel better I just had a microdiscectomy about 10 days ago so I know how it feels to have to can your physical

    projects for awhile....but guess what they will wait for you.

     

    good luck and best wishes for a speedy recovery!

    Thanks for the compliment!!

     

    If you are using the serial.asm code be sure to uncheck the exclude resource from build box in the compiler preferences.

    Right click on the serial.asm file in the project explorer click on msp430 compiler then uncheck the box.

     

    I tried to comment everything that needs to be un-commented for the serial terminal to work. That serial code of oPossum's

    was a great help in debugging I use it all the time now.

     

    As far as the exclamation point on the printf.c file goes, I think its mostly a syntax thing I have CCS 5.1 and I get

    "Possible assignment in condition 'c =*format++'. If it compiled and ran than I guess its not that big of a problem.

     

    This is a good question for oPossum the original author of the code, maybe he will see this and reply, I'm pretty sure

    he uses CCS as well.

     

    edit: Ive updated my CCS to ver 5.2.0.00071 and I get 6 function declared implicitly warnings when compiling.

    Due to the fact that the putc function is declared in the main and not the printf file.

    It loads and runs fine.

     

    I hope this helps

    STM32F4 gdbserver Error in "Initializing ST-Link device "

    in Other Microcontrollers

    Posted

    Some of these may seem like common sense but bear with me.

    Your usb cable is good?

    Are you using a usb hub?

    Your machine loaded the drivers for the f4 board when you plugged it in?

    It says STM32 STlink when you open devices and printers?

    Have you looked around on the ST e2e forum?

    I know that there is a STM32 stlink utility you can down load from here:http://www.st.com/in...duct/251168.jsp

    The latest usb drivers are there also.

    hope it helps

    Stm32f0 discovery st-link error

    in Other Microcontrollers

    Posted

    Yes it turns out that the way I was using the GPIO_init() function was incorrect.

    I was, as the st forum member clive1 put it:

     

    "The way your code works is that is trashes the setting of PA.14 (SWCLK) which is the clock for the debug interface."

     

    I changed it to portF and it worked fine... but

    blank.gif

    I need to rework the way I was initializing the GPIO to make it work the way I had intended.

    thanks for the reply

    Could you list your initialization script. It will be in the "Startup Debug/Analyze/Init" tabs.

     

    Is that in the atollic software?

    Im using eclipse with the gnuarm plugin and atollic gdb server

    here is the start up code Im using

    Is that what you wanted?

     

    I have played around with it a little more since I posted and I figured out it is

    definitely somewhere in my code, I was able to get the link to initalize by holding the reset button and starting the tool in the IDE.

    It took a few tries then worked, so I reloaded the program and as soon as I hit run I lost the link again.

    I reset the link again, using the same method as above and loaded a simple blink led program then I could debug no problem.

    Reloaded the other program and same deal lost the link!

    weird.

    thanks for the help

    Stm32f0 discovery st-link error

    in Other Microcontrollers

    Posted

    Hi

    I have been programming the stm32f0 discovery kit for a few days now using the

    Atollic gdb server with no problems whatsoever, that is until today.

    I was in the middle of debugging and lost the link to the stm32f0, now

    when I try to reinitialize the device I get the initialization error.

    I can use the stm stlink utility and load a hex file with no problems.

    I actually reloaded the same program I was working on when I

    lost the link. I have the Stm32f4 discovery board as well and I connected that

    to see if it was a driver issue but I have no problems initializing the st-link on that board.

    I connected the f0 board to another computer I have and I cant get it to initialize the

    st-link either. Does anyone have any suggestions for a fix, Im at a loss here.

    thanks

    Tim

     

    I posted this on the stm e2e forum as well with a link to this forum

    so maybe some more people will join this forum.

     

    I will update this if I can get the issue fixed

    web site / blog like 43oh for STM32?

    good one

    didnt KISS do that? :lol:

     

    I think if you set up a forum like 43oh for the arm cortex you would get a huge response.

    Just browsing the st forum is proof that people are looking for it,

    as far as a place to go and get some advice on where to start.

    There are some really experienced people on the st forum if they sighed up too it would be great.

    43oh is awesome and we know what makes it that way, if the community was behind it like it is here then its on!

     

    What does moderator entail?

    I have to agree with oPossum on the like feature, even if no one replies to your post

    at least you know it was useful to someone.
