I'm using STM32H747i-DISCO board. In Stm32Cube_FW_H7_V1.11.2 STM32H747I-DISCO example project -- stm32h747i_discovery_sdram.c, cas is 3. SDRAM worked fine with this setting. It didn't work when I changed cas to 2. Datasheet of Is42s32800G-6BLI shows...
Hello thereJust tried connecting my STM32F4DISCOVERY board to my PC. It appears that the underlying operating system recognizes the driver/device correctly. I've tried this on both Windows 10 and Linux and this seems to be the case on both.Here is pa...
Hello. I have a STM32H747XI project. This MCU has both CM4 and CM7 cores. I can reset both of them, when I use NVIC_SystemReset() function. How can I reset only CM7 core from CM4 core?
The data sheet on page one shows 0 to 3.6V input range but rm0440 says the ADC input range is -Vref to +Vref.where I believe the Vref is 3.6V? Can you explain the difference in specifications? Also, can you explain how this range changes with being s...
Hello, I am trying to transmit 64 byte data with DMA but if I am not use at least 10ms delay the data is not transmitted. How can I check the is data transmitted without any need of delay ? I try to check UART is busy or not fort that but its not wor...
I have found an issue with code generation from .ioc file. Using STM32H7S78 DK when choosing pins for FDCAN2 (I chose pb5 and pb6), after code generation it doesnt set pb 6 as an RX. Even if you manualy add it in the code it will remove it after code...
