Posted on June 13, 2013 at 16:04Hi everyone!Could you give me a complete example for SDIO raw read/write with 4-bits wide bus and DMA?I'm trying to do it in Coocox CoIDE. Unfortunately there are no examples included. Could you write a manual step-by...
Posted on July 17, 2013 at 13:24I'm trying to create a position-independent application that will run in one of two possible locations in flash as part of a firmware update process. A 'live' application will download a new application, check it for ...
Posted on May 12, 2013 at 18:52 hello forum , I want use only RX of USART1 of my F103 becouse I need TIM1_CH2 function on PA9 in what happens to PA9 if I enable both USART1 and TIM1 ? I dont want TX be enabled on PA9 - I ...
Posted on July 17, 2013 at 08:00Hello, I am making a project with STM32F407. I have a development board EasyMx PRO v7 from Mikroelektronika. When I am trying to connect (through SWD) the STM32F407 present on the board, there is no problem, the SWCLK...
Posted on July 17, 2013 at 05:19 I tried configuring. Im using the STM32F103RB /* Setup GPIO pin GPIO_USART1_TX. */ GPIO_InitTypeDef GPIO_InitStructure; // GPIO structure USART_InitTypeDef USART_InitStructure; // USART Structure USART_ClockIn...
Posted on July 16, 2013 at 16:42Hi,I need to do some timming analyses on signal. I use the capture mode of a timer.When I use the interrupt to capture event, it works but when the signal is fatser I get into overrun issue, I cannot run my CPU faster...
Posted on July 16, 2013 at 00:26Hi, I'm trying to communicate with a smart card using the usart on a STM105RC. I was successful doing that with normal interrupts, and now I'm trying to use the DMA with the USART for better performance. My problem is...
Posted on July 16, 2013 at 12:39Hi,I was wondering if it is possible to define software triggerd interrupts, i.e. an ISR is triggered by a value change of an arbitrary register.Any help is appreciated! #stm32f4
Posted on July 15, 2013 at 15:03 Hi, I'm working with STM3220G. I have to create a project that: configure GPIOA(pin1) in output for 20msec. After 20msec, starts a PWM for 5msecand so on... My problem is: when I see in myosciloscope, the wave...
Posted on July 02, 2013 at 18:51 Hi. I am using the KEIL exemple RL-CAN software for MCBSTM32F200 with and board that use stm32f207IF. The problem is that I can't change the pins of CAN2 sucessfully. The CAN works to send a messange but rece...
