Posted on October 01, 2012 at 13:36Hello, In datasheet um1052, chap 5.2.3, there is a method to determine the hall phase shift. I have a delay between the max of emf1 and the rising edge of hall1, but if I have a delay and an angle, I can know the s...
Posted on September 21, 2012 at 12:29Hi everyone, I am working with STM3210B-MCKIT and 3.2-Motorlibrary. My problem is the motor (Shinano LA052-080E3NL1) has not enough power, it is very easy to stop it with a hand. The power stage has during motor...
Posted on January 18, 2012 at 16:49The L6470 works well but seem to have a lot of quirks. Do you have any idea when the real application note will be available? Joe From therad ''EVAL6470 operation via SPI'' Posted: 5/17/2011 10:20 AM Enrico Poli '...
Posted on May 11, 2012 at 15:45Hello, has anyone tried out to implement a sinusoidal commutation for STM32 controllers? I'm already working with a block commutation quite similar to that: http://www.mikrocontroller.net/articles/STM32_BLDC_Control_wi...
Posted on August 06, 2012 at 15:08I am changing FOC motor control library to use it with a motor which uses analog hall sensors. To get the rotor angle out of the 3 phases of the analog hall sensors I am first doing a clark transformation with them ...

Posted on March 26, 2012 at 07:32There seems to be an error in the datasheet concerning FS_SPD. For starters the maximum value is h3FF and not hFF as stated. But if I am running in 128 microstep mode and the FS_SPD threshold is crossed it does not a...
Posted on July 17, 2012 at 08:03Hi,I am developing a product that is very similar to the buck-converter circuit presented in AN2544, using a viper12AS setup for 12V, 100mA output (using the 12V 200mA circuit as similar reference). This product is aw...

Posted on January 11, 2011 at 09:52I am designing a circuit with a L5973D switching regulator to provide 3.8v and am facing a peculiar problem. The circuit is as per the design reference in the datasheet and the feedback resistors are given to provi...
