I have a requirement for implementing firmware upgrade feature for one of our products which is based on STM32F412ZG microcontroller. I know that ST provides a system memory bootloader which already supports firmware upgrade using USB DFU class. But ...
I can build and run a program fine through IAR, but this board will not run when powered from a PC without using the IAR debugger. I assume this has something to do with the bootloader.
Hi, thereI am studying the sample codes : STM32F429I_Discovery_FMC_SDRAM and was wondering if the starting address of the SDRAM 0xD0000000 can be changed to something else. I don't see SDRAM memory section in the linker file and don't find any SDRAM ...
I am getting data from a current sensor through the adc of stm32f407. I want to export that data to MATLAB at real time or at least at sampling frequency of 10 kHz. I tried STM Studio but its sampling rate is only 1 kHz. So please let me know what sh...
Dear all,I'm checking if a variable assignement is atomic or not. I know that are many stuff on this subject but I need to approach from a low level perspective to better know what happen under the scene and then have better control of my code.To do ...
I'm in doubt about the transconductance parameter of the HSE oscillator in STM32L443.To select an appropriate cristal I studied AN2867.If the datasheet of STM32L443 which notes "Gm = 1.5mA/V" refers to gm the transconductance of the passive elements ...
Hello,Am using STM32F407IGT6 in my design. I power the VDD, VDDA & VBAT from 3.3V.I use an external voltage reference using LM4121AIM5-ADJ which generates 3V from 3.3V input.When I use this external reference of 3V as VREF+, I would like to understan...
I am using STM32CubeMx to generate default files to build with Makefile. I edited the main.c to print some logs using printf. I am unable to see the same logs in the serial. Am I missing anything ?
hello! I was devolving my project on the "STM3220xG eval-board" (based on controller "STM32F207IGH6"). Now as my custom made controller board is ready (based on "STM32F205ZGT6"), I ported my code for it by changing in peripheral's Pin-numbers and Ke...
Posted on September 28, 2017 at 06:50HI.Now I'm trying to implement TIM into the STM32F429i-DISCO kit.But I need to help how to calculate the prescaler and period value for user?As I know currently I used 180Mhz as system clock. and I want to set TI...
