The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
I have read previous posts ,,,I set up dma to read adc ,Although dma's destination address is allocated from AXI RAM, dma does not work when d cache is active.Can anyone share detailed information or a sample code about this?
Dear community,I have some issues with implementing an automatic wakeup with the RTC timer on my STM32L476RG (currently on the Nucleo-Board, will be later replaced with proprietary hardware). I generally have two wakeup sources: either the L476 is wo...
Hello all,I have W9816G6JH( Winbond) SDRAM interfaced with STM32f469 on a custom board.SDRAM is interfaced on FMC Bank2.I have generated SDRAM initialization code for MDK-ARM using CubeMx. When I Write and Read back on SDRAM address 0xD0000000 it sho...
I use a lot of STM32s in my work. The reference manuals, datasheets and so on are excellent but often contain a lot of near repetition between families. What I mean is that the details of the registers for (say) GPIO are often identical. But not alwa...
Hi,My slave device has only one bidirectional data line. Now I want to configure the SPI in the half-duplex mode. And I noticed that the reference manual gave an descripiton of 1 clock and 1 bidirectional data wire.I want to ask if ST has peripheral ...
Hi,I would like to know if MCUs of ST can operate in a vacuum environment.Thanks
Hello, I'm trying to use I2C and SPI simultaneously on an STM32F103C6TX.Both are working properly when only one of them is activated. However, when activating I2C peripheral with SPI already activated, SPI clock still works but the MOSI pin stops wor...
Hi there,here i'm for ask another help. I compile my program with keil and i read this data :Program Size: Code=15988 RO-data=360 RW-data=24 ZI-data=2088 How i can interpret ? I use one STM32G031F4P6 wher i have 8K of RAM and 16K of program. So i ju...
Im currently building boot loader to securely boot the firmware by signing the firmware images and verification during the boot of the firmware.So i'm using controllers like stm32f411,stm32f446,stm32f746 and stm32h723 ,I believe from the available do...
