Question
SPI clock rate for the 6470/2
Posted on February 20, 2018 at 16:13
The data sheet for the 6470 (and 6472) is not clear regarding the SPI clock rate. what is your take on this? the reason why i ask is that a clock rate was selected, boards were built and deployed. all was well. new revision to the board by adding another motor and one of the preexisting motors experiences a random bridge b stall. by changing the SPI clock rate this problem went away.
i already have a help ticket out to ST and they are unable to answer this fundamental question about their own product which is why i am reaching out to other users.
