Posted on July 30, 2015 at 18:53I have had partial success in using the L6470 eval board.  However, I found that when I issue a GoTo (ABS_POS) command, it doesn't execute right away.  Interestingly enough, it starts executing after I send a ''disabl...

Posted on July 15, 2015 at 22:01A colleague and I noticed something unusual when we were using an L6474 to drive a stepper motor.When the motor was stationary, we observed pulses on both of the motor phases.  This presumably corresponds to the PWM p...

Posted on June 22, 2015 at 16:05I've been encountering a strange problem.  I can use the L6474 to move a stepper motor pretty fast in the forward direction.  When I flip the direction bit though, I find that I can't make it move anywhere near as fas...

Posted on February 11, 2015 at 22:42I'm trying to use an X-NUCLEO-IHM01A1, but without an STM32 board. That is, I need to wire up each of the necessary pins individually, sending the proper signals via another microcontroller.For now, I just need to...

Posted on June 06, 2014 at 23:00I'm having trouble getting active halt mode to work on an STM8L.  I can get it to wake up from a halt condition using an external interrupt. However, when I try to do the same thing using the real-time clock, it doesn...
