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 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 15:47Hi,Using STM32F405RGTx, pin 64 is labelled PDR_ON while datasheet contains VDD.Which one is the correct one ?Thanks.
