Posted on April 01, 2015 at 11:51Hello,I'm stucked and want to ask for some clues.I'm building an 4-phase interleaved boost converter and I need to run a 4-channel PWM with phase shift (90 degree on each channel) and variable duty cycle (same for al...
Posted on July 01, 2014 at 14:28Hi,In my application, I have a PPS (pulse per second) signal with a period of 1 second and pulse duration of 200 ms. This external signal is connected to an EXTI line which generates an interrupt at each rising edge o...
Posted on April 06, 2015 at 20:41I developed an application using the I2S module on STM32F107VCT6.I'm using the MikroE compiller and there aren't any library for this. Then I configured each register accordong to the Reference manual (RM0008).Now I ...
Posted on March 31, 2015 at 08:20Hi,Which one is the best way of implementing stopwatch in stm32f429? Currently i am using soft timers for stopwatch. But it has time drift in long period when compared into my mobile stopwatch. I have using RTC also...
Posted on April 01, 2015 at 16:24Hello everyone, I am currently working on a project using the USB port to a PC host. My problem is that my device is detected as ''unknown usb device'' . Do you have any suggeestion? Also I am looking for a USB firmw...
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...
Posted on April 07, 2015 at 05:31As bright as the title suggests, I'm gonna post my setting over here~ Anyone please help me check it.. You have my utmost gratitude :) My UART4_Handler is empty, there's only a STM_EVAL_LEDToggle(LED4) to check its c...
Posted on April 06, 2015 at 08:30I was able to toggle gpio PA0 & PA13 , but when I try to do the same using PA1 & PA2 I'm not seeing any changes on these pins (used an oscilloscope to monitor). When I checked the schematic I could find these pins ar...

Posted on April 06, 2015 at 21:06I have a chain of 3 timers with TIMA -> TIMB -> TIMC.When TIMB is triggered it creates a pulse on an output pin via OPM. It then triggers TIMC to do an IC on its counter.What I want to do is to be able to programatic...
