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 28, 2017 at 11:46I found an example that ST gives for STM32F4 Discovery it's called FW_upgrade. Its a bootloader that uses the USB FS in OTG mode and it upgrades the firmware from a flash disk. BUT..this example uses the old librari...
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...
Posted on August 28, 2017 at 09:16Hi,We are using STM32F7 in our project, We have interfaced WiFi chip with STM32F7 on SDMMC2 interface.We are getting Fifo Error event when performing block data transfer using DMA with low layer driver. As per datas...
