Hello all, I have encountered unexpected behavior on the voltage level of PC12 when I enable PB12.My setup:PC12: Level high, output mode PP, no PU no PD, Output speed High. PB12: Level low, output mode PP, no PU no PD, Output speed Low.Without PB12 t...
Hello, I've an error in the interrupt but I don't see where it can come from.
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 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 ...
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...
