I'm using an area of Flash in an STM32U5 to store some information that I need to retrieve connecting the board to the SWD port. Data is sent out using the ITM port. All is working as expected connecting the board using the STM32 Cube Programmer, all...
Hi all,when running the same piece of code (math operations with random access to RAM) on the CM4 of the STM32G474 we measure smaller execution times than on the CM4 core of the STM32H745.The STM32G474 is clocked at 168 MHz and uses the SRAM mapped a...
Not sure why my previous post was marked as spam:Hello,I'm trying to do something relatively simple but can't figure out the issue. It might also be possible that there is no issue and my expectations are wrong about timer synchronization. I am using...
Finally after a long struggle, I was able to get into the system memory by changing to CP2102 ttl wire. Now I have another problem. Any solution to fix this? The PCROP_PDP bit is unchecked also.
Previously, I had a Raspberry Pi CM4 connected to an existing WebSockets server developed with Django Channels. The Raspberry Pi CM4 received data from an STM32F4 and forwarded it to the server. It also processed commands from the web server dashboar...
Hey everyone, new user here!In our project we are using:STM32F334R8T6STM32CubeIde Version: 1.14.1STM32CubeProgrammer release v2.17.0Debugger probe - Nucleo-F334R8 along with HAL implementation of handling communication using UART + DMA. Due to error ...
Hello, I have been working on the STM32G030K6T6 with DMX512 and TM1651 display for 8 months, and I am unable to find a solution to my problem.I am creating different patterns according to the DMX controller. One pattern involves the speed of blinking...
Hi!I'm a new STM32 user. I acquired a Nucleo-144 board today and noticed that there are no pins in CN11 & CN12. Just curious why.Thanks in advance.
We want to use HAL_SPI_Transmit to send data (master) in 8-bit units.However, even though we have set SPI_DATASIZE_8BIT, data is sent in 16 bits.Is there anything incorrect in the code below? uint8_t *spi_txdata;spi_txdata = (uint8_t *)malloc(2 * siz...
I am trying to change the system clock on my STM32F410RB using register programming. I have setup an SPI protocol to an external DAC IC which needs a minimum of 100ns (10MHz) clock period. The SPI allows for a maximum of 8MHz (fPCLK/2) at default clo...
