Posted on December 31, 2015 at 21:31Hi guys!Is it possible to use only assembler startup code without any libraries to create project for STM32F7? When I'm trying to include SystemInit() function in stm32f7xx.c file, I must include core_cm7.h header...
Posted on December 31, 2015 at 19:15Dear Friends and Colleagues!I'm interested to move from NXP chips to ST ones, so I've got a pair of devices and am currently trying to work with their bootloader via UART. The devices areSTMF030F4 (TSSOP-20)STMF03...
Posted on December 31, 2014 at 19:02hi every one i am a new elementary user of stm32f4xx(in particular stm32f4 discovery board) when i need to learn some new peripheral and that's application and functions, i Encounter a lot of Terms that i can not ...
Posted on December 31, 2014 at 17:20 Hi, I have a problem with proper main clock configuration in STM32F030K6T6. I've connected an external crystal 16 MHz with 2x15 pF caps, but the HSE is not starting. Variable HSEStatus remains 0, so the PL...

Posted on December 31, 2014 at 16:53I am using an STM32F407I want to generate exactly 400 pulses on PE5 or PE6 with a 50% duty cycle.I believe PE5 can be connected to TIM9 CH1, and PE6 can be connected to TIM9 CH2I have the PWM code running and I ha...
Posted on November 25, 2013 at 17:50Hi, This is a post that was posted before in a wrong thread, this post was : I would like to store my data in memory when the computing is done and used the data for the next use. I don't have the EEPROM memory o...
Posted on December 29, 2015 at 16:26I am developing application for stm32l0 using CUBEmx and keil, my intention is to transmit command to modem and receive response , so I have used to Transmit data and receive data through UART RX DMA.I am able t...
