Hello everybody,I'm trying to learn about stm32 microcontrollers and I thought the best way to do that was to start with assembly (well, maybe I was wrong about that, but I started with that). I'm just trying to turn on the user led on my nucleo stm3...
Hi, I have a code in which I am controlling a PWM output in Center Aligned Mode using Timer 2 Channels 2 (inverted polarity) and 3, both having their duty cycles changed by the functions:__HAL_TIM_SET_COMPARE(&htim2,TIM_CHANNEL_2,(duty_c-0.05)*400);_...
Hi everyone,I am using an STM32L412KB chip and I currently have an ADC channel configured to trigger a conversion on the rising edge of TIM15. I have the timer setup to be a 1kHz square wave. In the ADC interrupt handler I toggle an LED on my board, ...
I have a STM32L031K6 Nucleo Board...I want to use the DWT.. but I become this errors:../Core/Src/../Inc/stm32_delay.h:35:30: error: 'DWT' undeclared (first use in this function) uint32_t clk_cycle_start = DWT->CYCCNT;How can I Use DWT or Enable it...
Hi, I'm not being able to make LPUART work.What I tried:Use HAL drivers.Clock LPUART with LSE.Use different board.I also configured PB11 as output and it toggles normally.PB11: TX(output)PB10: RX(input)This is my code:LL_IOP_GRP1_EnableClock( LL_IOP_...
We have a system that uses hundreds of modules. Each module has 4 STM32F303 MCU's. Within a single module we would like to have one programming interface. Is there a means to program 4 MCUs with one programming interface?
Hi everyone,I can write to flash of STM32F103, max value of uint32 variable 4294967294.It is possible to write when you write it to flash directly.But I want to write it to flash with uart receiving. But when I put the rows (which is writed Bold in c...
Hello,I'm trying to understand: When will the HAL_UART_Receive function return HAL_TIMEOUT ?Will it happen only when the "Timeout" value has passed ?/** * @brief Receive an amount of data in blocking mode. * @note When UART parity is not enable...
There's an error either in the datasheet and CubeMX or in the IBIS and BXL files.In the datasheet and CubeMX, J14 pin on STM32H745IIK6 (UFBGA 176+25) is labeled as VSS, but in the BXL file (Altium SchLib) and in the IBIS file, it is labeled as VDD.Co...
I'm trying to run the aws_demos project from X-CUBE-AWS on the B-L4S5I-IOT01A development board. I've successfully programmed and run the provisioning image. I've successfully built the aws_demos project, and have the "B-L4S5I-IOT01_aws_demos.sfb" an...
