STM32H745ZI Quad-SPI: Delay before accessing MemoryMapped storage

Hey together,I have a question regarding the Quad-SPI used in MemoryMapped mode. First of all some context for you. Our plan is to use an external Flash at the moment 25Q16JV to place some code/data onto this chip. Our planed processor will be the ST...

Has anyone been successful in getting a STM32F7 series to work with Raspberry Pi 7" touchscreen?

STM32F769I-DISCO offers a part to get it compatible with the RP MIPI DSI 7" Screen (B-LCDAD-RPI1) but there is no firmware support from either company. Does anyone have any information on how to get the two compatible? and if not, is there any other ...

STM32F103CBT TIM4 PWM with DMA results in Hard Fault

Hi, Beginner question: Over the last few days I've tried to generate a PWM signal with a STM32F103CBT on Pin 46 (PB9) with a variable pulse width, but apart from generating a signal with a fixed Duty Cycle at the desired frequency (800kHz - I want to...

STM32L442KC, shutdown mode and RTC alarm to wake-up?

The datasheet says that shutdown mode while RTC is running (via external crystal, aka LSE) is definitely available. I need to wake up at exactly midnight once per day, hopefully for several years.If I understand correctly, the shutdown mode allows wa...

UART is not working in interrupt mode

Uart is not working in interrupt mode in Stm32f205.​​HAL_Uart_Transit ​is working but HAL_UART_Transmit_IT is not working for UART of Stm32f205.​Please suggest what is missing in configuring UART.

STM32F103C8T6 SPI capabilities

I've been trying to use SPI on the STM32F103C8T6 for a project I've been working on for a while now. I still can't figure out how to buffer data using SPI to an array in a continuous stream.This stream is continuous because there is no pause or break...
