I am using STM32H7B3I-DK running a touchgfx application and acting as SPI Master, and Nucleo-H743ZI as SPI Slave. Both are configured in interrupt mode not using HWNSS. The Master is sending 1,2,3,4,5,6,7,8 but the slave is receiving random numbersI ...
This is a question about programming style, preferences, efficiency, and risk.We are working on a state machine were multiple conditions are checked for a potential state transition. We are debating what is better, safer, more efficient, or simply mo...
We are currently using the ST32F4 MCU.During operation, we are using self-diagnostic code provided by ST, but after 8 days of normal operation, an EXT_SOURCE_FAIL occurs in STL_MainClockTest(), causing the MCU to reset.When EXT_SOURCE_FAIL does not o...
Hi All,I'm having a terrible (fun) time trying to get the DP83848 to work with the STM32H743 (RMII).No packets, no interrupts, nothing. - it's just dead to the world.I can get things working with the LAN7842 and I can get the DP83848 working with the...
Hello there. I am working on STM32G030 based FW. It appeared the TIM1x_CH1N doesn't work. I found out this part of code doesn't initialize negative channel(stm32g0xx_hal_tim.c). Moreover it may skip all channels configurations. It seems to be a hard...
Hello,Today, I was receiving my eeprom data normally with my normally working I2C code, but when I entered debug mode, the uwtick increased on my processor, but it was not receiving my commands. The LED indicating that the code was running was not bl...
I had debugging problems with a H7 target, and by stepping thru the boot process I found the following line in SystemInit(): /* * Disable the FMC bank1 (enabled after reset). * This, prevents CPU speculation access on this bank which blocks the...
i have interfaced stm32 and Sd card performed different operations separately and i have interfaced stm32 and tft wave share(ili9486) display and able to display some graphics separately ,now i am trying to fetch a image from sd card and display it o...
All my code works on RTOS.When I enable D-Cache，fs_mount() from FATFS on SD card returns FR_NO_FILESYSTEM，SD card can not work.When I disable D-Cache, fs_mount() returns FR_OK, SD card can write and read.But at the same time , i need to use Ethernet ...
Hi, I am using STM32h735g-dk development board, STM32CubeProgrammer and ST link to flash the development board. I tried to flash program the development board using the ST link and STM32CubeProgrammer. Once, it got programmed, but after some time, I ...
