Posted on April 06, 2014 at 06:30Hi all! I want to control 3 phase motor (I get HDD motor from old HDD), and now I can generate 3 PWM signal on 3 channels but they are same, not shift phase 120 degree! Please help me! I use STM32F4 discovery board a...
Posted on July 21, 2015 at 14:07We are using the L152 processor in a new design. This is the first time we've used the STM32 family and it is mostly working wonderfully. However, on the three prototypes we have, only one crystal oscillator works rel...
Posted on July 21, 2015 at 13:42Hi, I want to know how could I get a range 0-5V in ADC. I know that normally it's from 0-3V. It's enough connecting 5V to Vdd? Thank you
Posted on July 21, 2015 at 15:43 Hello there I've been trying to implement an IIR biquad lowpass filter with the DSP library lately. I started out by designing the filter in MATLAB and calculating the IIR parameters before I pretty much ...
Posted on July 20, 2015 at 16:58 Hi, I had to measure frequency but in a large range of frequency. the target is a STM32L I would like to realize something like : T2 generate a 10hz signal on PA0(using internal clock, and compare/match) ...
Posted on July 21, 2015 at 15:29Hi all, I have a STM32F103 and a Secure Access Module (SAM) (PCM1.1 by NXP). The SAM needs a clock input and an I/O pin to send and receive data to and from the MCU. In my design, the clock port of SAM is already conn...
Posted on March 30, 2015 at 08:46I am trying to implement iir Band Pass filter design in STM32F429i discovery kit. I konw that it needs coefficients to be generated from matlab and feed them into cmsis api to achiev filtered data. My SOS Matrix look...
Posted on July 21, 2015 at 13:07Hi I have read through a couple of posts that clive1 has made regarding phase shifts in toggle mode. I need 120º shifts between each of the 3 PWM channels. I get 120º shift between channel 1 and 2, but anything more t...
Posted on July 17, 2015 at 12:50Hi all, I am using a STM32F103 MCU and I wanted to enable TIM2 timer and then perform some operations upon signals received by the timer, first by polling and then using interrupts. I have setup my timer i.e. TIM2 as ...
Posted on July 07, 2015 at 13:26Iam having big problems with the high resolution timer on the STM32f334microcontroller.I am using a period of 0xD3C2, this would normally mean that writting 0xD3C2 to a compare register is full duty cycle (or zero - ...
