How can I maually calculate the values of SCLL and SCLH for the I2C modules?
I'm using a custom STM32L452RE with the processor clocking at 80Mhz.
Changing MITx_CRRx and ARR on the fly
Hi, I am trying to change MIT4_CRR2 on the fly to change the period of the PWM output by doing:void EXTI4_IRQHandler(void) { /* USER CODE BEGIN EXTI0_IRQn 0 */ htim4.Instance->CNT = 0; htim4.Instance->CCR3 = 0x0000A978; /* USER CODE END EX...
voltage regulator
where is BYPASS_REG pin of voltage regulator in stm32f407vgt6 and how it was enabled and disabled?
Unstable work on STM32H743IIT6 mcu.
Hello community! My mcu is STM32H743IIT6 tqsp176 from blue waveshare board. I create a new project from Cube with HAL. Then I make the simplest flashing cycle of the LED:volatile unsigned long x = 0; while (1) { while (x++ < 2000000) {} x =...
STM32F105RBT6 Spi read wrong data.
I am configure w5100 using spi.but at the time of reading its show wrong data.Refer Code link: https://www.carminenoviello.com/2015/08/28/adding-ethernet-connectivity-stm32-nucleo/
SPI1 Clock speed
Hello,i am using a Nucleo - F411RE board and i want to create a sine wave with an external DAC (mcp4922). So i initialized a SPI connection to send my sine wave table to the external DAC. The frequency of the ouput sine wave should have 40 KHz. At ...
STM32F0 and SPI with CPHA=1 an NSS pin
Hello Forum,I am new to STM32 but familiar with MCUs. My Problem is the SPI interface.In the datasheet there is a figure (figure 277 of document RM0091) where all four possible combination of CPOL/CPHA are shown. There is also the signal nss in the f...
I am looking for an example for STM32H747 (dual CPU) MCU, best way to share data between processors.
1. Array of bytes? Read and write between CPUs.2. Peripheral allocations to CPU1 or CPU2? Should allocation of peripherals handled by only one CPU? What will happen if both CPU's are asking for same peripheral. How to handle this scenario.
