I'm using i2c to connect MPU6050 in asynchronous mode (means interrupt driven). I've implemented dfa for that. Everything works fine, but there is strange interrupt right after Re-Start. SR1 == 0. Right after second read of SR1 there is right value (...
Posted on September 28, 2017 at 16:47Hello everyoneYesterday i buy a Nucleo-F746ZG, i installed SW4STM32, ST-LINK/V2 Drivers and http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-...
I have a project that uses the internal RC clock used by the STM32L071VBT6 as the system clock. During the test, it was found that some of the other communication ports were not working properly under the low temperature of -40 degrees. The latter an...
How can I check the revision of the m7 core without checking the registers?The revision r0p0 and r0p1 have a problem. When debugging jump to a timer interrupt or debug sequence is bad.So I would like to know how to check revision in advance when buy...
Hello, I'm wonder if the F303RE Nucleo board can be configured to use an external 16MHz TCXO. If so, where can I find documentation on how to configure.Thanks in advance,Dave
Hi,I'm writing a bootloader, the application binary is read from a SD card connected via SDIO and will be written into the SECTOR 2 of the micro controller (starts at 0x8008000 == APP_ADDRESS), the bootloader is stored in SECTOR 0 and SECTOR 1, start...
So somehow through my chain of execution I end up herevoid _exit (int status){ _kill(status, -1); while (1) {} /* Make sure we hang here */}From disassembly it seems that the functions preceeding it areITM_SendChar()and before thatHAL_CAN_Rx...
Hi,We are using STM32F479 processor in our design. Now we are in process of optimizing our code, How can I determine the maximum Stack and Heap used in the Project. We are using Keil Compiler and application is based on RTX OS. For thread level optim...
Hello,We have a custom System-On-Module based on the STM32F750N8H6 MCU. We successfully installed 50KB-size U-Boot SPL and 220KB main U-Boot images into the internal Flash, and they work.Could please someone explain how is that possible? Device datas...
Hi,I have experience of 16bit microchip micros using embedded C, and i am about to move across to ARM RTOS C++. I have narrowed my chip vendor down to ST. As i am starting from zero on ARM development, could you offer advice on which is the easiest d...
