control SK9822 2020 LED's via SPI using Registers

HiI need to control some SK9822 2020 RGB LED's.I figured out that with the information on this website I can control them over SPI in transmitt only mode.The Problem I have now is, that I need to do it using Registers and can't use CubeMX for setting...

What is the startup time of PVD?

I want to use the PVD function of my STM32U5(but I think this applies to nearly all STM32s) to detect when my supply voltage goes over(!) a specific threshold. But it might already be there when I enable PVD. Since this means looking for a zero on PV...

Flash memory size STM32F303RET6

Good morning,I need to create a shared memory space between two applications (Bootloader and Application).I am working with STM32F303RET6 MCU.I want to do this inside flash memory and not SRAM.For that reason I found many examples and codes where fun...

how to write on the CCR2 register.

removing chip cause unexplainable artifact.

I have a st chip (HT35) with the STM32H735G-DK Discovery Kit. Projects was complete and running fine. We then had to remove the OCTO SPI nor flash chip because we need access to Pe2. but after removing the chip the app froze after MX_TIM4_Init(). The...

Stop flag is not generated with STM32H743BI manually written i2c driver.

Hello, I am trying to write manual I2C driver for STM32H743BI controller. Here system clock is configured for 200MHz and APB1 clock for 50MHz. Below is my initialization code. While testing stop flag and TXIS flag is not set after setting CR2 registe...

Multi-channel ADC reading in continuous mode.

Using an STM32H757-EVAL (don't use CM4) with CubeMX. Configured my ADC1 as follows:DMA is:Start the process as follows (both calls return HAL_OK):I allow the code to run for 10 seconds and break. The m_hv_status_values buffer still has the initial va...
