Which values can I suppose for Cin, Cout and Board Strays for STM32F103 and STM32L4 for HSE and LSE using the ecuation 1 in the following datasheet of the abracon "https://abracon.com/uploads/resources/PierceOscillator_Fundamentals.pdf"
Hello,while DS12110 Rev 4 for the STM32H7 has such a section as 6.3.33 I did not see such a section in datasheets for other CPUs and I miss these section!
My code to write directly to registers for I2C communication between Lis3dh accelerometer and STM32L053R8T6 is not working. Only CMSIS drivers are used. Could you give some suggestions. [I am looking to learn the basics of STM32 and have tried HAL d...
I write a delay function using systick,it works well in stm32f103rbt6，but the same function does not works well when I select another chip stm32f105rbt6.when I toggle the led every 500ms,it is actually toggled every 1562ms,much slower than expected ...
Posted on September 26, 2017 at 18:04Hello,as part of a larger project, I want to connect a custom JTAG-based debugger to the Cortex M3 present on the Nucleo STM32 L152RE.My debugger has already been fully tested on other development boards and wor...
Posted on December 28, 2017 at 11:00I'm trying to setup the STM32F7 device with the LCD driver using STM32CubeMx. But despite the description, I don't see the STemWin library in the Middleware tools list in the STMCube. What I'm doing wrong? Or what...
Am working on a SPI driver for STM32H7 (for Ada language).I use the board Nucleo-H743ZI.I'd like to make SPI4 working as a master in full dulplex mode (no DMA mode).What are the proper steps to follow? the reference manual is not very specific (for m...
Dears I'm using the board STEVAL-SPIN3202 to drive a BLDC motor using hall sensors for speed sensing. When creating the code using STM MCWB 5.3 software, I choose hall sensors mode for speed sensing with one shunt resistor for current sensing. The pr...
Hi guys,I'm using the latest ST generated I2C hal driver on an STM32L0. On my I2C master, I'm requesting to read from a register, which sends the following sequence:Start -> Address (W) -> Register 1B -> Stop -> Start -> Address (R) -> Data 4B -> Sto...
