Posted on September 21, 2016 at 17:07Hi,I'm having difficulties with STM32F4xx SDIO when using DMA transfer in circular mode (single buffer or double memory buffer alike). SDIO transfer (multi-block read or write) completes successfully, however DMA...
Posted on September 18, 2016 at 17:47Hi. The function BSP_AUDIO_OUT_Play stops the program flow completely even before the return value can be read. The audio buffer is output as a never ending loop. The BSP_AUDIO_OUT_Init worked well with no error ...
Posted on September 21, 2016 at 17:42I discovered ~450uA additional current draw coming from the STM32F101 in Stop mode. This condition occurs when an external pin interrupt from a peripheral goes active during Stop mode even though the NVIC is dis...
Posted on September 21, 2016 at 11:30We are using STM32 L0 series controllers (STM32L031F6P6, STM32L051R6T6) in our new product design. We are using STLink-V2 debugger with Keil IDE to program and debug the target. In the process we are not able to...
Posted on September 20, 2016 at 15:11Is it possible to prefetch flash data to the ART data cache without stalling execution? As far as I can see the only possibility is using DMA, probably using the DMA2D engine. So the idea is not to copy data fro...
Posted on September 15, 2016 at 12:53Hello everyone,i am using CubeMX 4.16.0/1 with Nucleo-F401RE or Nucleo-144_F746ZG. I want to attach an ili9341 Display on SPI2 and an SDcard in ''SD 1bit'' mode. If the initialisation of the SDcard is performed (...
Posted on September 20, 2016 at 13:55Hi thereI am trying to set up the output compare value of timer3 in my STM32F030 to trigger a single channel, single shot ADC conversion every 60ms. I'd like to use the HAL drivers (see UM1785, I am bulding the p...
Posted on September 21, 2016 at 00:27Hi all, I am using stm32f746disco and working in the LWIP stack, having the provided examples as a guide.I can receive and transmit data successfully, but only I can send data to the current tcp_pcb running in th...
Posted on September 20, 2016 at 16:14Hello, I try to count impulses from a rotating motor (pulse length: 280 us) I use STM32CubeMX (Version 4.16.1; STM32Cube V1.0) to configure the STM32F746. I configured TIM9 slave mode for external clock source mo...
Posted on May 15, 2015 at 19:15Hi, I'm porting an implementation of SD over spi to stm2 using Cube library. It seems that the communication micro to sd card is ok, it seems that the sd card answers like it should but it looks like the microcontroler...
