Posted on January 31, 2018 at 10:30 Hi, I'm using IHMOA03 to control NEMA23 format stepper motor running in half-step current controlled clock step mode. I put the scope on the sense resistor R1 to monitor the phase current and it is not what I e...

Posted on January 26, 2018 at 18:33 Hi, I am using a http://www.mouser.com/search/ProductDetail.aspx?r=511%2dX%2dNUCLEO%2dIHM03A1 on top of a STM32F411RE to control a NEMA23 format stepper motor. In trying to improve the torque and resolve stalli...

Posted on January 24, 2018 at 09:11Hi,  I am using NUCLEO-IHM03A1 eval boards on top of a Nucleo STM32F4IiREI to drive a NEMA23 stepper motor.The motors are stalling at relatively low speeds with no additional load. I don't seem to be getting the re...

Posted on April 14, 2017 at 19:26I have been using the AC6 eclipse IDE on Nucleo F411RE for some time. About every week or two it locks up the system and I have to power cycle to get my computer back :(Last time this happened, I has to reinstall the...
