I went through the examples on the ST site which have the direct implementations (not using CubeIDE generated code HAL for GPIO, SystemClock, ... config implementation)https://github.com/STMicroelectronics/STM32CubeL0/blob/master/Projects/NUCLEO-L053...
Hi everybody,I'm trying to configure the OCTOSPI1 bus as Single-SPI to read the status register of an external memory (MRAM).What I expect to see on the scopeWhat I really see:The MCU sends the comand (0x05) on the SI line, generates 8 clock cycles a...
Dear Team,We design a board in which one host controller si driving the STM controller over LPuart1 whose pins are as below.Part Number: STM32L073PC4 - LPUART1_TXPC5 - LPUART1_RXNow, We want to update the firmware of STM using the host controller on ...
Hi, I'm pretty new to stm32.My goal is to use HAL_TIM_Encoder_Start() , HAL_TIM_Encoder_Start_DMA(), HAL_TIM_Encoder_Start_IT() commands from Hal library. I have the stm32f407 Discovery board.in polling mode//-----------------------------------------...

I'm using the STM32U5 and when I create a basic project in Keil and compile, I get the following error:"Error: L6218E: Undefined symbol SECURE_SystemCoreClockUpdate (referred from system_stm32u5xx_ns.o)."How to fix this?I don't want to use STM32Cube ...
Hello, I'm trying to set up SPI communication between an MCU as master and the STM32 as slave. Data reception in the STM32 works fine, but I'm not being able to transmit data to the MCU from the STM32. I'm using the interrupt callback to read and sen...
Hello,I'm using STM32 NUCLEO board.In my application, I want to read GPIO PORT A input register (IDR) & (pins setup as inputs).With that variable, I want to do something, if specific pins are HIGH, execute the if cycle.As an example, I want to execut...
