STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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 developped a graphical demo with the STM32H735 discovery kit, and the minimum frequency of the OCTOSPI to have a clean display is 66 MHz (framebuffer = 480x272x32). Now I want to use in my application an External RAM with QUADSPI (framebuffer...
Hello there, recently i have found a error in the application note an4839.The strongly-ordered memory region in the Table 2. Memory region shareability and cache policies is remarked as non-schareable. Howerver according to ARM DUI 0646B ARM Cortex-M...
Hello, has anyone ever used UART to read arrow key? I tried using STM32 MCU on CubeIDE, but can only get two characters ASCII number 27 and 91 and couldn't get the third character which is supposed to be 'A' for Up key, 'B' for Down key, 'C' for righ...
I have some projects that were left inadvertently with some function calls that write 0x00 bytes into the data EEPROM. They work properly. I have tested it.I detected the problem on a prototype board with an old sample of STM32L152C6T6 and this made ...
I am using STM32h753XI.The MCU uses 2 SPI channels (SPI1 and SPI2) in slave receive mode.The MCU uses 2 DMAs channels (DMA1 stream0 and DMA2 stream0) to read the data from SPI1 and SPI2 and write it to SRAM1 and SRAM2 respectively.The input SPI sclk ...
I want to synchronize multiple stream with one SAI DMA request. Is it possible? How?I know DMA streams can generate event and I can synchronize others with that, but I think this is just create event after transfer completion, but I don't want transf...
We have seen PVD triggers when there is transient load of 1A added on the 3.3Vdc (loaded additional to our design through electronic load) and it triggers when the transient load dips the 3.3V for duration of ~450 micro seconds.We have seen BOR trigg...
Hi there!I need your help before i became crazy. I configurate (with DMA) 9 ADC input plus one for Vrefint channel of my STM32F051 discovery, Now my problem:i read a wrong value of Vrefint channel the value is equal a Ing1. But if i configure ony Vr...
