Float variables print on Debug UART

With the help of STM32 CUBEMX generated basic code for IAR-EW and I have design a small code to print float variables on UART for debug purpose in STM32F413RH. This is working fine in IAR-EW but same things when I used in Atollic TrueStudio it is not...

STM32F429 SDRAM and FMC/LTDC/DMA2D priorities

Posted on October 04, 2015 at 15:16Hello!I'm trying to run STemWin/FreeRTOS/HAL on STM32F429IG revision Y at 168MHz.SDRAM (IS42S16400J-7TLI) connected to FMC controller and runs fine by itself (CAS_LATENCY_3/CLOCK_PERIOD_2/RBURST_ENABLE/RPIPE_DELAY_...

SDIO doesn't work - STM32F429ZIT - FreeRTOS - CubeMX 5.0

Hi,I had a working project on the STM32F4-Discovery board (STM32F407) with FreeRTOS and FATFS on uSD card. I wanted to move to the STM32F429 because the FMC provides a lot of flexibility over the FSMC for my project. For the life of me, I couldn't g...

How to come out of HardFault in STM32 program

I am getting signal trap at HardFault_Handler ​while I am running a program. How to debug and solve?

The original software embedded in

Hi Everyone!I've been working with STM32F769I-Disco & STM32H753I-Eval boards, and I lost the original / demo software / demo firmware / with which both boards comes.Please, Can you help me in the way to find both software packages? In st.com WEB page...

Invalid RTC readings after initialisation.

Hi I am using the RTC on the STM32L433 processor , and works well in periodic and Alarm. I can read in the date and time without any issues within these interupts. But after the RTC is initialised for the first time, reading the date and time regis...

STM32F730R8 status

Hi there,For my upcoming project I am planning to use STM32F730R8. Which is suitable for all the requirement I have. Can you suggest me is it a good dicision. Or this model is on the way for obsolete. Because I need this controller at least 5 years....

Regarding Controlling of DAC in STM32F303

HelloI'm trying to implement 4-20mA output using DAC CH1. I found out a strange phenomenon during the experiment for the DAC output test.the issue has at both non-triggered mode and software trigger mode of DAC.[phenomenon]I found that the DAC output...

STM32L071RBT6 is in use. There seems to be a TTL port and a CMOS port, but where is the description of which port is TTL and which port is CMOS? Also, how should I switch when all ports support TTL and CMOS?

Hard fault error while step into or step over, But not during free run of debuggging

During the debugging of my code, I see a strange behavior.I am using STM32F767ZI and trying to debug using ST-Link flashed with jlink firmware.While debugging the firmware using the gdb, at a particular assembly instruction, the control jumps to hard...
