Hello,We use the CubeIDE generator for most of the code initialization. Therefore the HAL is also inizalized. The function HAL_Init(); is executed and TIM1 is started.The Hal ticks work fine.Now I want to use the Chanel 1 of Timer1 for a PWM signal o...
Hi,I'm trying to create multicore communication. I want to call interrupt in the second core. Firstly I thought that I can somehow make hardware semaphore release interrupt in the second core. But then I found something better in the CubeIDE:It looks...
Hi there. I am developing a bootloader application in IAR EWARM environment on my STM32f415 card. I'm having trouble uploading it to my stm32 card when I want to debug the bootloader code.Bootloader code starts from 0x08000000 and application code st...
/* USER CODE BEGIN 2 */ // CS pin should befault high HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12, GPIO_PIN_SET); uint8_t TX_Data[13] = "Hello World!"; uint8_t RX_Data[13]; /* USER CODE END 2 */ while (1) { /* USER CODE END WHILE */ ...
I'm writing code for the STM32F411 and STM32F103 MCUs using the ST HAL library. The firmware reads an IDR directly using the HAL function HAL_GPIO_Read_Pin. The function is called 2 to 3 times in main(), that is, the IDR register is 'polled' more tha...
In my application I need to design a multi purpose digital input which can operate in 3 modesON/OFF detectionFrequency measurement andPulse CountingI can do the last 2 using HW Timers in Input Capture mode and configuring it for both edges. In the al...

In Standby mode it is given like this.... (1.2 V domain powered off).All 1.2 V domain clocks OFFwhat does this means?
Right now, I am able to get I2C data from sensor. I have generated PWM signal separately with TIM_CH2. But I have no idea how to generate pwm from I2C signal. So, basically I need to control amplitude of pwm from i2c signal. I am using NUCLEO-L011K4 ...
