Posted on August 23, 2016 at 04:36I am using STM32F3 Discovery board to generate six-step PWM signals for BLDC motor drive. The switching was done in SysTick ISR by generating a SW COMG event. When I checked the PWM output on oscilloscope, however, ...

Posted on November 30, 2015 at 10:52Hi, I am using STM32F301. If I configure the GPIO pin to be output mode, and configure it to be open-drain with pull up, what would be the pin's current sourcing capability? What is the value of the internal pull-...

Posted on October 08, 2015 at 11:07I checked the datasheet and couldn't find the information whether the thermal pad should be connected to board ground, although another engineer told me it is very common to do so. Would anyone please advise whethe...

Posted on June 25, 2015 at 09:14I started to learn to use FOC Lib 4.0 to control a PMSM motor with encoder. I used MC workbench to configure the HW and generated code to SystemDriveParams, then I used the example project for STM32F30x_Workspace.uvmp...

Posted on April 07, 2015 at 11:54TIM1 PWM output seems to be a lot more difficult to understand than TIM2~TIM5. I was totally lost when trying to understand how MOE, OSSI, OSSR, CC1P and CC1E work together to control the output level of CH1 and CH1N...
