Hi,I have studied UM1052 user manual about vector control implementation on PMSM. But I have two major problems. The first one is with the SVPWM implementation on sector 4.11 and the other one is "Circle limitation" on sector 4.12.1 .I am actually lo...

Posted on July 16, 2016 at 09:55Hello!I'm working on UART comunication between stm32f407 and PC. I want to transmit 4 character via ''senddata()'' function shown below.USART_SendData(USART1,'D');while(USART_GetFlagStatus(USART1, USART_FLAG_TC)==RESE...

Posted on June 12, 2016 at 08:51Hi!Im trying to use two EXTI on PE2 and PE3 pins simultaneously. Two push bottons are connected to these two pins with a pull-up resistor and a capacitor filter prohibitting debounce phenomenon. As shown in the code b...

Posted on May 30, 2016 at 10:31Hi!I'm trying to run a bldc motor with stm32f407 IC. The most common method to do that is six-step mode control. I configured TIM1 in complementary mode. but as you know, timer mode must be changed during each step.For...

Posted on November 01, 2015 at 07:54Hi!Actually I'm new in STM32.I have a problem in creating pwm. while making pwm in 20KHz with timer1, the frequency suddenly changes during the run! it is programmed to be 20KHz but it jumps to 2 or 3KHz.i want to...
