Just tried B12 exactly same sysptoms:-

All looks OK but no message on TT (com5) see below

A couple observations:-

The erase seems to work now. Tried the boot0 to VDD link and then an erase.
A reset of the STM32 shows com5 being disconnected and reconnected.
A compare of the hex file and STM32 flash memory are identical.

The cable used seems OK - Used to connect my phone to my PC and reset shows the connection.

hello hello :)

i managed to install STM VCP drivers on windows 8.1 64bit
and after installation i am able to connect from teraterm via microusb to ARMite (firmware b12).

my procedure:

1) install
VCP_V1.4.0_Setup.exe

2) then follow this tutorial.
install unsigned driver by switching off driver signature checking:
http://revryl.com/2013/08/06/install-unsigned-drivers/

3) time to run driver installation.
C:\Program Files (x86)\STMicroelectronics\Software\Virtual comport driver\Win8\dpinst_amd64.exe

after this steps i was able to see in device manager
>STMicroelectronics Virtual COM Port as com3

4) restart discovery board by power cycling it.
and now connection is working fine

hope it will help to others

I'd be interested to see the results of following dmasz's post above - I have had to jump through stupid loops to get CERTAIN things working in windoze 8, by making those changes so that you can install unsigned drivers. This seems to be a Windoze 8 issue, and not something that is a problem in earlier windoze 7.

It's a pain in the arse to do, and involves a couple of reboots just to enable installing unsigned drivers and to get back to the desktop proper again, but it did seem to work for me.

I suspect that the trouble started for Bizzie, when windoze did that update. The forced signed drivers thing must has been part of the update, thus - the mess you have now where anything unsigned is blocked by the OS.

@Grogster

Installation ST-link and ST virtual port with fresh installed W8.1 pro as admin works OOB. Well I spent almost 2 days with trying and testing. Fresh W 8.1 installation solved my problem.

I hear that.

Sometimes it can be quicker and easier to reinstall the OS, rather then playing about for too long trying to make something work.

I does depend on machine and circumstances though.

Not sure if a full reinstall of 8 is something Bizzie is prepared to do though.

Grogs
The unsigned drivers thing relates to 64 bit Windoze and can be easily circumvented. Just Google for it.

Matherp: CTRL C now working. Running a few play type programs and all seems well except... very occasionally the serial goes a bit wonky.
It suddenly stops showing characters, then as you keep typing the older characters appear on each keystroke and is a bit stuttery.

e.g.
Typing: ABCDEFGHIJKLMNO
Displays: ABCD|Pause|EFGH

Only happens very occasionally and have to power on/off to fix it. Using mini USB serial connection.

Great work, you and Geoff.Edited by aargee 2015-03-13

For crying out loud, all I wanted to do was flash this blasted LED.

I have finally got the STM32 working over USB!

I followed dmasz's instructions but had to repeat the last step several times, not sure why.

I also used an account with admin privileges instead of giving the admin password, of course I do not know if this was essential or not.

I will now have a play with the beast.

Thanks you all for your input.

This morning, I flashed one of my Discovery F4 boards at home without any real trouble. (Win7 machine already set up for STM32 dev work.)

Plugged the Discovery board into an XP machine at work and after a short driver search and some Teraterm foolishness (baudrate = 38400), I got MMBasic running.

The following:

Timer = 0
Print Timer
For i = 1 To 1000000
Next
Print Timer

spits out '8448' - just under 8 and half seconds to run. I'll compare to a Maximite tonight.

Visit Vegipete's *Mite Library for cool programs.

Not sure if this should be here or not.

I do not seem to be able to set the time on my ARMmite (12B)

Here is what I did (copy/paste from TT)

> ? time$
16:14:48
> time$="11:59:00"
Error: Expression syntax
> ? time$
16:16:35

@Bizzie

Copy/Paste in TT behaves strangely (you need to use ALT not Ctrl key).

What if you type in: Time$="11:59:00"

Do you still get strange behaviour??

Sorry mislead you about the Copy/Paste that was only to get it to the forum.

All seems to work fine now!

> Time$="12:14:00"
> time$="12:14:00"
> ? time$
12:14:42

Not sure what finger trouble I had!

Anyone knows where I2C pins are? Anyone tested DS3231 RTC on ARMite?

According to the manual

I believe I2C is on pins PB6 - SCL and PB9 - SDA of the discovery board.
ie pin 92 (SCL) and 96 (SDA) of the Micro

This is gleaned from the circuit diagrams for the ecompass and the audio. What I can not locate is the pullup resistors.

Just found the pullups for the I2C 4.7KEdited by Bizzie 2015-03-15
