Posted on July 18, 2015 at 23:13Hi,I'm trying to enable the cortex's fault exeptions for my stm32f7 board.Everytime I call HAL_NVIC_EnableIRQ(UsageFault_IRQn); or try to enable some other Fault I get an Hard Fault.I already tried to access the reg...
Posted on July 19, 2015 at 15:46I have been using the following setup for trying out a few demo programs. I use the jLINK OB. However it appears that I have blocked my STM32 by uploading bad code.Is there some means of resetting the board in the cur...
Posted on April 08, 2014 at 20:48Hi I'm working on STM32F401,I configure I2C1 port as an I2C Master at ''init_I2C1(void)'', and I succeed to communicate with the slave side. Now I'm trying to configure I2C3 port as an I2C Master at ''init_I2C3(void...
Posted on July 17, 2015 at 17:44Hello,After my first steps with the discovery board, I designed my very first PCB with a STM32 MCU (STM32F417VGT6), which I intend to program via SWD (SWDIO, SWCLK, GND, 3.3V). Unfortunately I don't get a connection t...
Posted on July 19, 2015 at 08:10I know that when a c program is compiled and flashed it goes into the flash memory and the flash memory contains the text section, initialized variable section and Read only section. So I just want to know when a prog...
Posted on July 14, 2015 at 22:12Hi Everyone.I'm having some doubts about the discovery boards.I have a nucleo board and a STM32F429I discovery board (the one with a LCD).In the nucleo board I had next to no problems sending data to the serial monito...
Posted on July 14, 2015 at 07:15I am a beginner in STM32. Recently I surf the Internet and find some codes written by others. They all says that the RCC should be configured at first as follow: 1. Reset the RCC register; 2. Open HSE; 3. Wait for HS...
Posted on July 17, 2015 at 05:54Guys, where can I find ''main.h''....? I use Keil MDK... Thanks I read from : ''Developing applications on STM32Cube with LwIP TCP/IP stack '', page 39 How do I choose between static or dynamic (DHCP) IP address alloc...
Posted on July 17, 2015 at 18:46I'm new to the STM32 and am trying to read three ADC channels on an F0 part. I've used the STM32CubeMX utility to configure my hardware and then have looked over some of the ADC examples in the STM32Cube_FW_F0_V1.2.0...
Posted on July 17, 2015 at 00:17The user manual for the STM32L053 discovery board shows an ''MFX'' module that looks like it does interesting things, including perhaps measuring the current consumed by the chip. Is there any documentation / app note...
