Hi,I have a board with STM32F103VET6 mcu. Sometimes when power on at startup, my mcu sometimes does not start as it should start, and it only start to work when the software is reinstalled.When the problem occured, I have checked the flash data from ...
I want to achieve high sample rate into stm32f446, so I found that I can triple the sample rate using "triple interleaved mode" and DMA. I thought I can make this easily by defining each of ADC1, ADC2 and ADC3 as continuous conversion mode with direc...
When I calibrate the HSI frequency of an STM32F7 writing to HSITRIM in RCC_CR register, which is the calibration step? I mean, how much the frequency of HSI change if increasing or decreasing HSITRIM in 1?Doing the same with an STM32F0, ref. manual s...
The firmware I want download is on https://my.st.com/content/my_st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32-standard-peripheral-library-expansion/stsw-stm32027.license=1542095271296.product=STSW-STM32027....
https://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-expansion-packages/x-cube-mems1.htmli downloaded this software.i also used the gui program. but i have to read under 0.01g so gui...
Posted on January 21, 2014 at 14:29I use NVIC_SystemReset() in order to reset the system. I am using STM32F103 in my application and RTX rtos. The problem is that if called NVIC_SystemReset() before the RTOS started, the software reset worked. If ...
I'm using the STM32F767ZI MCU and with its RTC function. But my quartz crystal is not accurate. According to the document of the MCU, the accuracy can be calibrated (it said in page 35/255: Digital calibration circuit with 0.95 ppm resolution, to com...
I found a version macro in the library but it seems to be wrong. Please see attachment. What should I do to check the SPL version in the code?
Hello, We are developing a watch-like wearable device with LCD. STM32L4R-Discovery board is a nice reference design for STM32L4R+AMOLED development. It would be also nice to have a schematic for the adapter board MB1314B, which the AMOLED is attached...
Using STM32F030 / F042. I have a GPS receiver onboard which produces a very accurate pulse-per-second signal (~40ns). I want to use this timing source to keep the system clock, or at least the RTC accurate. The user may wander in and out of GPS recep...
