STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on June 25, 2014 at 11:55Hi,I'm using an STM32F4 and have configured IOs as pwm outputs with internal pull down. These pins have been connected to an input of another chip which has a 5V pull up on its inputs. After some time the processor br...
Posted on June 25, 2014 at 23:56Hello,I have been using version 4.2.0 without problems but I had a DMA problem which I thought that could be fixed in version 4.30I did the upgrade from Check for Updates option. No issues there.However version 4.3.0 ...
Posted on June 17, 2014 at 11:31Hi all,I'am using USB device CDC class to communicate datas with a host. But I've a strange problem. (I'am using the STM32F429i Disco platform)The STM32 code create a memory area with 00 01 02 03 04 ... datas and then...
Posted on June 24, 2014 at 21:06Hello, I am using the STM32F4 discovery board. I have a project in which I have a timer which generate an interrupts @ 100Khz. In the ISR it stores a new value to a variable. Now how can I use the DMA to ...
Posted on June 25, 2014 at 19:36Hello all,I am looking for some suggestions or help on locking the Flash ROM during read and writes. I am using STM32Cube with FreeRTOS and have implemented the FS OTG MSC for accessing the Flash ROM on my board (it i...
Posted on June 25, 2014 at 15:47Hi,Using STM32F405RGTx, pin 64 is labelled PDR_ON while datasheet contains VDD.Which one is the correct one ?Thanks.

Posted on June 25, 2014 at 15:07I'm sure that this is a really silly question, but is there actually a reference manual for the STM32F401 chips? I can't see one on the design resources page. The STM32F401 Discovery documentation refers to ''RM0344''...
Posted on June 25, 2014 at 16:07The problem was indeed the reenumeration. Pulling DP low shortly triggers reenumeration, and than Windows recognizes the new mode. Works for both directions, from regular mode to DFU mode and vice versa.
