The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello, maybe it's not the right place to ask this type of questions, in case I apologize.While trying to understand how ARM assembler works, I came across this problem and I'm currently struggling to find the answer.Before explaining better my questi...
Hello everyone!I have 2 fixed PWM of 40kHz (TIM1_CH1, TIM1_CH1N) and one modulation at 80 kHz fitted into the others, matching the steps by zero.Instead of this, I have this signals:There is a gap between them of 1us.This is the timers declaration: v...
I have a setup with a STM32L452 Nucleo-64, and has connected a CAN transceiver to it. This is in turn connected to a CANDO dongle to a PC. With the current setup I'm currently able to transmit data from the STM32 to the PC with no fail. The reception...
I am trying to adapt some code generated in Cube-MX for use on the STM32F4RG used in two very similar projects. The code was written for a drone flight control board and the oscillator used https://www.digikey.com.au/product-detail/en/murata-electr...
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...
