    Could you tell me how long the reset pulse must be to reset a mdot unit? I am developing a piece of code in arduino and I need to know when I use digitalWrite, how long I should have it down and up again to reset the unit. Or, at least, the minimum time.

    Also, if it has to be low or high when I want to reset and put it into sleep mode. Actually, I haven’t found anything about this on the developers pdf.

    According to the STM32F411 datasheet, reset needs to be held low for at least 300ns… yes, that is nano seconds.
