Posted on September 19, 2013 at 17:37Hello everybody,Is it possible to link same pin number of different GPIO ports on the same EXTI line ? For example, create an interrupt on line_0 for the GPIO pin A0 and the pin B0. It seems impossible to achieve...
Posted on March 31, 2014 at 02:51I am experimenting with the STM32F429 and wish to use the LCD-TFT controller (LTDC).I am interested in generating monochrome 640x480 VGA video and hence only need 1-bit output rather than 8-bit RGB. Does anyone know ...
Posted on March 31, 2014 at 02:29Hello, I am trying to activate the interrupts on PC4-7 so that a flag will appear whenever these pins are set high. I have the base structure of the code completed, however whenever I try to place a break point to se...
Posted on February 17, 2014 at 16:07 Hi, I'm using the F407 (Discovery) as a SPI-Slave with DMA enabled and a ''data ready'' signaling line. I'm currently trying to transfer data in dual buffer mode (the host cpu might also send configura...
Posted on March 29, 2014 at 02:21 Hi, I'm entering in STOP mode with the command: PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI); But, when it resume from STOP, I cannot write to EEPROM anymore. I'm unlock...
Posted on October 29, 2013 at 15:56Hello everybody, I'm looking for a working example using OUT Endpoint on STM32F4 Discovery board. I have no success with it. I modified Demo sample for an OUT Endpoint and Custom usage, and try to send one byte rep...
Posted on March 29, 2014 at 17:53 Hello stmGuys. I'm having a problem configuring my DMA. I've tried everything I can imagine and it still doesn't work. I want the DMA to transfer data from a memory array to the GPIOD->ODR register. Here is my DMA...
Posted on March 30, 2014 at 08:39Hello,I want to use WFI, but I'm wondering how it works, what triggers the WFI to exit low power.I've defined systick for 1uSec (I'll use it later for some delays).I've defined timer2 for 100mSec.I need to do some ca...
Posted on March 28, 2014 at 21:35 Hello, For a project I am working on I would like to generate interrupts on both edges of the HSI clock, for synchronization purposes. The sysclk is based on the main PLL, sourced from HSE. ...
Posted on March 19, 2014 at 19:43Dear All,I would like to create a 1.5 MHz Sine Wave using TIMER + DAC + DMA.I have started from the DAC_SignalsGeneration example for Discovery board and then I have modified the TIM_TimeBaseStructure.TIM_Period fro...
