Posted on August 15, 2016 at 07:22Hi,I am running a STM32L152 into stop mode. The MCU sleeps most of the time (waking up every 1hr to read sensors). As I have the watchdog running, I am using RTC to generate an alarm every 10s (watchdog period is ~2...
Posted on August 13, 2016 at 00:06Hi,I have a big problem where I seem to overload the AHB bus. The main components that are involved are SDRAM and LTDC. I am using one layer (at the same time) in svga resolution and the frame buffer is in SDRAM.Jus...
Posted on August 16, 2016 at 20:12Hi! I have a CS4344 DAC connected via I2S to my STM32F407, converting values at a rate of 44.1kHz. In parallel, I would like to convert values through the internal DAC, at the same rate, in a synchronized way (every...
Posted on August 16, 2016 at 18:09 Hi, I have the attached code. This is supposed to set up the ADC for 2 injected channels, 0 regular channels and DMA. Additionally, this is supposed to use TIM1_CH4 to trigger the conversion start of th...
Posted on August 08, 2016 at 22:39Hi, I just set up DAC output on the STM32F303 Discovery Board and I'm noticing a lot of wideband noise on the output (about .5 volts peak to peak), even when I set it to a constant value within my program. Is there ...
Posted on August 12, 2016 at 01:40dear all,I have studied the camera sample project, it uses dma from camera address to LCD memory address. I do not have lcd in my design, so when i run the camera project, i see one whole black image. Is there a way...
Posted on August 16, 2016 at 09:56Hi all,Is there a way to calculate the size of used RAM at running time. So that I can calculate how much RAM is still available for use. Actually I have to show used RAM in percentage to my product customer.
Posted on August 16, 2016 at 13:29 Hello, I want to read/write files on a usb stick in my application and I already have generated a project with the help of ST32CubeMX for my Nucleo-F746ZG board. The configuration in CubeMX is: ...
Posted on August 13, 2016 at 00:31Hi, I'm new to programming the STM32 micro. That's way the Cubemx tool is very helpful for initializing the STM32. Also ther are a lot of examples in the repository, but i don't understand why the examples are not w...
Posted on August 16, 2016 at 04:31I have a project generated by ST32CubeMX that uses the SDIO hardware to talk to SD cards that is generating a hard fault when doing any sort of file access. I'm not sure exactly what is going on since the project i...
