  3. Hello, I'm Federico an Italian newbie to ARM.
    I bought one of Mini-ST32 from china, but I'm not able to understand how to download the obj to the Cortex.
    Could anybody send a drowning man a rope?
    Instead of a rope i could buy also an howto for the dumbest in the world.
    Thank so much!
    Fede

  6. have you considered its possibilitys to be used as a mobie multichannel analyzer for radioisotope identification and measurements?

    It would be interesting, to feed it with a live input from a Photomultiplier and extend the Channels of the Spectrum to a maximum (at least 1024-2048 channels would be awesome + export to Sd as txt file with bin number and counts)

    would be more than interesting, what is possible with this board (just started to think about to get my own ^_^)

  7. I change PWM channel to PA8, but I recive some noise. What I do wrong ?
    I.e. I change timer to TIM1 and port to PA8 (TIM1 CH1)

    1. This strings:
      TIM_OC1Init(TIM1, &TIM_OCInitStructure);
      TIM_OC1PreloadConfig(TIM1, TIM_OCPreload_Enable);

      and add this:

      TIM_CtrlPWMOutputs(TIM1, ENABLE);
