 IDE?  IDE??? what do you take me for - a muppet?? :)  naah mate - the
only reason i can't bludgeon or nuke IDEs is because they're just
programs.

 arm-none-eabi-gcc - i got it frooomm... errr....  ah!  here it is:

 stm32sprog - worked a treat, just needed to short boot0, apply power,
and run it:

 indeed there is - would i use anything else? :)

 naah they're going with the ST board support software.  it's all
pre-prepared as shite proprietary compiler project structure so i made
a beeline for libopencm3.

 why? :)  i used a USB-to-Serial port which was 8 quid and that's
quite a lot for a USB-to-serial port, and all the software is entirely
software (libre)

 oo i do have to look at alternatives to the STM32F, but pricing needs
to be competitive (around $2.40)
