Posted on May 29, 2017 at 18:30 Hello, I am using PWM 2 mode to generate step pulses for a step/direction interface (and counting pulses thru the timer update interrupt), But sometimes I am loosing the first step because of the preload of t...
Posted on August 28, 2017 at 14:02More.Both the 'F4 and 'L4 RMs clearly state that the USB modules are not capable of Low-Speed Device (underpinned e.g. by DSTS.ENUMSPD not having a documented setting for Low Speed).Why is it then that both CubeF4 a...
Posted on August 27, 2017 at 14:23Hello All,I am starting with stm32f407 Discovery board . I am trying to program it through IAR toolchain,From where should I start please suggest me.ThanksRegardsGulfan Ahamad#stm32f407-discovery

Posted on August 25, 2017 at 10:53Hi all,I am trying to get a hight speed write to SD via SDIO as well. I use a project generated with Cube MX, 4bit SDIO and DMA. But I only get a write speed of about 300 kBytes/s. I write 1000 times a 100 byte bloc...
Posted on August 26, 2017 at 03:11Hi.This may be a ultimate dumb question.I'm having hard time trying to make use of pins that are mapped to complementary outputs TIMx_CHyN (TIM1_CH2N, TIM8_CH3N, ...) to take edge interrupt on corresponding time cha...
Posted on August 28, 2017 at 10:35Hi everyone,I am a biginner in ST-controller programming. Last week I spent time hunting the internet for finding some solutions about how to make a NUCLEO L476RG work as USB HID device. So I launched the example en...
