L9958 SPI control
Posted on July 22, 2013 at 15:39The question is related with the command word under the SPI protocol title. In this protocol uC should sent the command word to start protocol but I can not find the structure of this word. In datasheet the CFG_REG an...
L9942 - Motor lose some microsteps
Posted on August 08, 2013 at 20:17I want to control a stepper motor (http://pt.farnell.com/astrosyn/163/stepper-motor-1-8deg-5v/dp/9598650) with L9942 from ST.But i have some problem because the motor dont rotate uniformly (lose some step): My curre...
Migrating from Power board MB459 to IHM023V2
Posted on July 09, 2014 at 04:41All - to save you a bit of trouble, here is what I found when I migrated my existing power board (discontinued by ST) to the new IHM023V2 power board:1) The connector pin-out to the STM32F10X-128K-EVAL is identical.2)...
Problems with SW_MODE bit in CONFIG register
Posted on July 01, 2014 at 01:11I'd like to enable the HardStop interrupt (i.e. SW_MODE = 0) when I home my motor and then disable it afterward so that subsequent moves do not trigger the interrupt. Enabling the interrupt before I start homing via ...
