A lot of unanswered and unsolved questions

The quality of this forum is low. Look at all the unsanwered posts (0 answers). Also sorting does not work. And this forum works differently than all the others.

L433 UART Tx Output is Not What is Being Sent

Hello:I am trying to determine why the LPUART is transmitting out the values I am seeing. They make little sense. Here is the UART setup:void MX_LPUART1_UART_Init(void){ hlpuart1.Instance = LPUART1; hlpuart1.Init.BaudRate = 9600; hlpuart1.Init.WordLe...

ITM_SendChar on NUCLEO-F767ZI with ST-Link Utility

Hi,I've got a NUCLEO-F767ZI and I've just tried calling ITM_SendChar and watching for the output using ST-Link Utility SWO Viewer.I see some strange characters in the SWO Viewer but not what I've sent.It looks like it is sort of working but that the ...

SQLite on STM32F7 series

I'm trying to implement a DataBase connection with STM32F779NIHx. I included the sqlite sources but received an error because the ioctl.h file is not present within the STM32F7XX HAL Driver. Where can I retrieve it?

What's the meaning of this compile/debug error. I didn't have it before.

I made a very simple code following youtube tutorial. I made it work a month ago. I come back and run it in debug mode, it works. I want to make a change in the PWM's length. It doesn't change. I notice the debug mode saying that my source files a ar...

Cycle Counter different when stepping

Hello,I'm currently doing some performance measurements using the DWT's CYCCNT register. As I understand the RM, the CYCCNT counts up for every core clock cycle (except when halted). However, I get different values in CYCCNT when stepping through the...

I am trying to create keil project for STM32L476VG Discovery board, I tried to include LED API through board support packages from Manage Run time environment.It leads to open STM32CubeMx and I have generated the code, While building the code I am ge...

Running STMCUFINDER in 64-bit Linux (Opensuse)

Hello,recent STMCUFINDER installs without errors on Opensuse Leqp-15.0. Running as in the 32 or 64 bit ennvironment however gives: LANG=C linux32 ./STMCUFinderchdir /devel/STMCUFinder/.current dir /devel/STMCUFinderError: Unable to initialize main cl...

Is it possible to use the external SRAM or external SDRAM for code space on the STM32F469I-Eval board?

Run code from external RAM

Hello,for a new project I plan to execute the code from an external SRAM connected via FMC.Are there any experience on speed leakage?In an other Topic I read that there are losses of 4 times the speed compared to the embedded Flash.https://community....
