PWM: drive output low in disabled mode

Posted on April 15, 2014 at 16:26I'm using TIM1 for a 6-step motor control on a STM32F2xx. According of the table 4 in DM0004234 application note, I update OCxE and OCxNE at each commutation, to select a new step. When OCxE = 0 and OCxNE = 0, the ou...

data transfer speeds

Posted on April 14, 2014 at 21:23Hi all, i'm dissapointed from transfer speeds on STM32F407 @ 168MHz core, i'm measuring roughly 10.7MHz using FSMC with the code: runTIM_stoptime();do{  hh=fsmc_read( 0 );}while( (ui32--) > 0 );stopTIM_stoptime();USA...

Cortex-A chips for Generating Pulses?

Posted on April 14, 2014 at 11:33I am now using a Cortext-M3 chip(STM32F) to control Stepping Motor in an industrial equipment (Only generating pulses and direction signal to send to a stepper driver). Its maximum frequency is 72MHz so I can't add m...

SWD Interface for STM32F051 and / or STM32F030

Posted on April 15, 2014 at 01:51I have a STM32F030 design which I migrated from a STM32F051 design.  When I read documentation on the programming interface, it specifies SWDCLK, SWDDIO, and NRST.  I noticed however that the Discovery board has anot...
