Posted on February 14, 2016 at 21:24 Hi, i write bootloader with sdcard upgrade option. During first bootloader start (after power on, or MCU programming using stm-vldiscovery programmer) everything works well. When I restart MCU using N...
Posted on September 02, 2016 at 19:53I am unable to get any output from the COMP1 comparator on an STM32F072RB on any pin other than PA0. The datasheet ''STM32F072x8 STM32F072xB'' states on pg 41 that COMP1_OUT should be available on pins PA0 PA6 an...
Posted on September 21, 2016 at 02:43Hi dear all,I am using STM32F070RB-T6 to control a buzzer for 10 sec beeps and a power ON press key in my circuit.How to use RTC, DMA here in LSI mode?Kindly share code and disscuss it.Thanks in advance.
Posted on September 01, 2016 at 05:34Hello, We bought 10 of these boards and want to run USB host and log screen outputs through UART6 to Hyperterminal. When we run the USB host example, things work fine. When we run UART_com_IT standalone, things w...
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 (...
