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...

Does the STM32CubeIDE have a truncate function?

I am working with a Nucleo-L476RG board, and I am writing a program that generates HMAC-SHA-256 values. I want to truncate the output of the generated HMAC value to only output n amount of bits. For example, if my generated HMAC value is 80 bits, I w...

How to wait for Interruption to continue code execution ? Or better non CPU blocking solution for my code.

Hey,I'm basicly filling a tank with liquid and I have 2 level sensors in this tank. These level sensors are connected to GPIO_EXTI of my MCU so when the water reached the sensor level, an interrupt occure. If the tank is filling or emptying, I must d...

STM32L4 ADC oversampling - What is the total sampling time ?

I using STM32L4 ADC in my project to sample analog acceleration data. The ADC conversion is triggered by 10kHz timer by which i was able to achieve 10kHz sampling rate using DMA. Now, i wanted to implement oversampling by a factor of 2. Now what is m...
