Posted on November 02, 2012 at 04:04Dear Friends,I would like to use more than one pins PA0, PB0, PC0 for external interrupt 0, for detecting 3 buttons. I tested with PA0 and it's working well but I want to expand more PINS in similar interrupt. Doe...
Posted on November 01, 2012 at 18:35I have a peripheral bursting 8-bit parallel data at 56MHz gated by a data valid signal. Can the STM32F4xx support peripheral to memory dma at this rate? What is the max rate the STM32F4 can handle dma requests? ...
Posted on November 01, 2012 at 20:17Hello, I am trying to attach external PHY chip to my STM32F4Discovery board. I am using the 'stm32f4x7_eth_lwip' example from the ST site. I think for people that have the bigger evaluation board with already sold...
Posted on November 01, 2012 at 17:29So does the whole family of STM32M0-STM32M4 have their own StdPeriphDriver offering? Under the advisement of my hardware guide, I am trying to test out the Freescale Freedom board after I have developed on the ST...
Posted on November 01, 2012 at 15:27hi ST experts, i am testing Virtual COM Port function using stm32F105(connect line),the USB OTG FULL SPEED library is 3.3.0 and PC driver is VCP_1.3.1 on Win7,i find when send just 64 bytes(Max packets size) f...
Posted on November 01, 2012 at 07:44Dear all, MCU we are using is STM32 F103CBT6, on a motor driver application. Wehave encountered a strange phenomenon that Bus Fault occurred randomly duringnormal operation, and the fault message shows that the PC...
Posted on October 31, 2012 at 08:05I emulate an I2C eeprom. I first receive the address, then I set the DMA-Source pointer to my tx-array (DMA_MemoryBaseAddr). As I have configured autoincrement, several bytes will be transferred. When the second re...

Posted on October 31, 2012 at 16:38 I want to capture a systick time by occurence of an edge. I see the value is captured but the DMA is not done. Why? (STM32F4) TIM_ICInitTypeDef TIM_ICInitStructure; RCC_AHB1PeriphClockCmd(RCC_AHB1Pe...
Posted on October 31, 2012 at 12:58There's no examplo using CCM RAM on the STM32F303 stantard library. I need to know how modify the EWARM liker icf file to add the CCM RAM section and how to put an assembler routine in this section.
