Pins connection SWD st-link to an external STM32F103RBT6

Hi!I'm trying to use my ST_linkV2 debugger to program an external STM32 microcontroller using SWD, is this configuration ok ?: CN4 (STLlink) Vdd----------> Vdd (stm32 MCU) SWCLK------> PA14 (SWCLK) ...

Reading data from external ADC chip using GPIOC port and DMA2, does not work as espected.

Hello.I am trying to read data from a 12bit ADC AD9226 connected to port GPIOC, on STM32F407VGT6 clocked at 168MHz. On port PA8 there is a 42MHz clock for the external ADCand also the same TIM1_CH1 I triggers the DMA2 to transfer data from pheripher...

STM32H750VB SPI Slave MISO last bit returns low to early

Hi there,I am using the STM32H750VB as an SPI Slave in Interrupt mode and it is working but I am not happy with what I see with my analyzer.SPI is working with Idle-Clock Low and aquiring data at leading edge. LSB first.That's all how it should be bu...

On STM32F429, why DMA2 MemoryToMemory transfer can go up to 96MHz???

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...
