Posted on June 15, 2016 at 15:41 Hi there, I'm working on custom board based on STM32F103 and the IDE is Keil. I will use UART2 to print some debug logs. To do this I add the fputc function to my code in order to redirect printf to...
Posted on June 16, 2016 at 14:26Hi.I am using discovery board with STM32F100; I have made a code to generate a sinusoidal waveform through pwm via lookup table method.I think I miss something in computing the output frequency of the sine wave.Here i...
Posted on June 16, 2016 at 16:43 I'm facing with a problem regarding continuous acquisition of ADC channel in STM32F I use the interrupt at the end of conversion to call a callback function to store the acquired value. The problem regards t...
Posted on June 16, 2016 at 13:17Hello EveryoneI am trying to run my code on stm32f4, with use of interrupt routines. I have an 9dof imu including mpu6050,hmc588,bmp058. So i am interfacing 3 EXTI rsubroutine to read imu and this has been successfull...
Posted on June 15, 2016 at 17:43Hello guys, I'm trying to install u-boot on my development board STM32F407 . After loading the binary image, the UART1 interface does not work . I'm using the version available from the website emcraft for the board S...
Posted on June 10, 2016 at 17:23The purpose of this post is to save other developers the time I have spent tracking this down. Bear with me on this - its messy. Line 1108, of stm32f1xx_hal_rcc.c is if (pllmul == aPLLMULFactorTable[(uint32_t)(RCC_...
Posted on June 16, 2016 at 10:22Hi,I have found some errors in the IAP over Ethernet example. I don't know it this forum is the right place to inform ST about errors, is there a better way to do so? Here are the issues:- stm32f4x7_eth.c line 299: as...
Posted on June 16, 2016 at 10:30 Hi, I'm facing a strange problem with UART DMA int in a FreeRTOS-based project. When I call the DMA setup function (below) from a given FreeRTOS task, it works just fine and the ISR is executed. However...
Posted on June 16, 2016 at 08:09Hi all. In our system we use one of the general purpose timers in ''Encoder interface mode'', that means, the encoder clocks the timer counter to count the pulses. I found this in the documentation:''Encoder interfac...
Posted on June 16, 2016 at 08:28Hi. I would like to ask if speed setting of a pin in GPIO->OSPEEDR register is relevant also if a pin is configured in input/alternate mode? Or is this setting relevant only for output mode? I am asking specifically f...
