Hello, I was looking for an stm32h7 part where I could provide voltage to the internal ldo from a vddldo pin to achieve lower power consumption using an external smps. I'm looking at the h743 lineup but cannot find any package with such exposed pin e...
So I adjusted the ARR and Prescalar values to adjust the pwm frequency(20KHz). Timer Clock is 200MHzI want to change the resolution in the run time with a function. How can I change it?Changing the ARR value will change the resolution?Thanks in adva...
I want to use ADC1 16 channels to read different analog values. So whenever there is a data in the channel then I want to read the 16 channel data in Interrupt mode. I dont want to use DMA Interrupt mode and Poll Conversion mode. Is it possible to do...
Hello,I've a MT25QL128 IC interfaced with STM32F767 controller on QUADSPI. there is external crystal of 8MHz. I want to check timings req for read, write and erase the flash IC, so that I can write some data into flash. I've referred application note...
MCU:STM32F0discoveryTools:STM32CubeMX5.6.1+Keil5.3OS: Windows 10proQuestion:When I use the PLC system`s interrupt, always the interrupt just trigger once in the first scan time.But in the MCU system, I find that the interrupt can be triggered by the ...
Hi guys, I recently posted similar question but now I have some actual measurements.I have measured the frequency of the clock signal comming from st link to microcontroller which was 8 MHz (correct). Then I did setup of prescalers, configure system ...
I'm setting the SPI input clock for the port I'm using at 50MHz to allow SPI speeds up to 25MHz for use with an SD card under SPI. However, this gives a minimum speed of 50MHz/256 = 195KHz and this is too fast for initialising some SD cards. I need t...
HiI am using the STM32F407 discovery board. Yesterday evening, I tried to init the SPI1. Then something strange happened. I suddenly receive the error message "Fail to insert all hardware breakpoints: You may have requested too many hardware breakpoi...
I am writing an application and bootloader to STM32H7.I append some data to the end of the application. My bootloader needs to be able to read this appended data.When my bootloader first writes the application via (erase->write to memory).When the sy...
In Cube, setting the Comparator to work with the DAC requires the DAC to be set as a GPIO however, I'd like to use the GPIO pins for other tasks, is this possible or does the DAC need to output on the GPIO for the comparator to work?
