STM32H7 - SPI test will not work unless I add pull down resistors to the MISO line

I have a test running on a Nucleo-H743ZI2 board which consist on a SPI master and a SPI slave sending data to each other. In particular, the master sends the slave the following sequence: {0xaaaaaaaa, 0x55555555} and the slave sends the master the op...

STM32H750B-DK sample multiple GPIO with DMA

Hello thereI am trying to port a logic analyzer from STMF407: https://code.google.com/archive/p/logicdiscovery/to work on my STMH750B-DKI even found some pins I (think) I can use (PB4,PB6,PB7,PB15 (right arduino connector (D0,D1,D10,D11)I tried to po...

STM32Cube IDE I am converting a basic program that I have written ages ago running on a CUBLOC CB30 connecting to a Picaso processor by 4D Systems (4.3inch touch display) I am converting it to c using STM32F401 Nucleo-64.

The serial output sent to the uart in the 4D displayis typically a string consisting of the following 3 items,#define Put_string                        &H00, &H18Const m_Alarm_Set                     As String = "Alarm set" #define NUL             ...

The data is not coming on MOSI line when using the DMA forSTM32H7

Hello,I am trying to transmit data to DAC using SPI DMA method on STM32h745 I tried all the methods that mentioned on forum. But i did not get the data on MOSI pin, when I use the polling method the data is successfully transmit .const uint16_t addr[...

Is it possible to make TIM1 of STM32F103 capable of both timer interrupts and capture interrupts? Is there any sample code available?

STM32H7 ADCs with DMA when D-Cache enabled

Dear all,I am trying to configure ADC1, ADC2 (ADC1 and ADC2 in multimode) and ADC3 running simultaneously with DMA.I have a running code for STM32F7 series and I assumed that I could use DMA in the same manner but DMA cannot store data taken from ADC...

First time programming a stm 32 - key matrix

Hello all!I'm in the process of designing my first full custom sim racing steering wheel. I have designed and ordered a pcb with a stm32f103cbt6 mcu. The pcb works good (so far) and i have it connected to my pc via a swd clone st link debugger. I am ...

In STM32U5, What is the right Oversampling Ratio for ADC1 14bit to achieve 16 bit. Is there a formula?

following is observation with different OR 

STM32H7, MDMA IRQ double hit... and working only with debugger attached.

Hello,I configured the following ADC flow:ADC3 => DMA2 => SRAM => MDMA => DTCMEverything was working well using the MDMA in single buffer transfer mode. In each MDMA interrupt I was reconfiguring the MDMA channel to get ready for the next DMA2 transf...
