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...
Posted on January 21, 2013 at 19:48I have a STM32-F4 discovery board, specific model ♯ STM32F407 VGT6. Having connected it to my computer via USB I have successfully run its test programs. Additionally I have successfully built a test program that c...
Posted on April 10, 2013 at 15:44 Hello, I'm using a STM32F4DISCOVERY to program the firmware of my future board. I want to use the integrated 12 bit DAC of the board to generate analog simple signals on the A4 and A5 pins, but I don't wa...
