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...
Posted on September 20, 2016 at 21:49Hi, I've been struggling to get interrupt for DMA working. I got it working for USART interrupt. I'm configuring for USART1 and DMA1_Channel5. My problem is that I don't get an interrupt for the DMA. So is ther...
Posted on September 17, 2016 at 23:25Hello,I have a STM32F469-DISCO board with an WL1835mod SDIO on it. I'm running linux on the board with all kernel, drives and fs. It was running properly with and without DMA enabled. So I decide to remap my exte...
Posted on September 21, 2016 at 01:16Hello all,I am using a STM32F411 on a custom board I built and am programming it using mbed with gcc under Linux. I am trying to understand how all the interrupt priorities work and think I have it figured out, b...
Posted on September 20, 2016 at 21:50Hi ,I am working on STM32F415RG, I recently wrote a bootloader program, which is doing its job of jumping to a specified location. Now my bootloader(at addr 0x08000000) is able to jump to my main application(at a...
Posted on September 19, 2016 at 16:47Hi, I have some code running when on a certain condition, it goes into standby.I have pre-configured the RTC to wake the processor after 30 seconds. Everything works as expected except if cycle the power whilst i...
Posted on September 20, 2016 at 17:31We have written a blog post describing how to get the best out of the combination of the DRT tools (with advanced debug and optimization) and the STM32Cube and STM32CubeMX components. Hope you find it useful: htt...
