RS485 Uart DMA Tx
I am using stm32f4xx, and I am using UART with DMA normal mode. I have a problem with the Transmit Completed state, When I using the TxCompletedCallbacks I get hard fault error so I learned it does not using with normal mode so I am trying the Transm...
STM32L475 RTC interrupt for every 1s
I want to configure the RTC interrupt for every 1s in L475. Since all RTC interrupt are routed through EXTI, is it possible to generate the interrupt periodically without depending on external signal? Something like second interrupt (SECIE) in STM32F...
Resolved! ST’s secure service in STM32H750
We are working with STM32H750VBT6. Our project works with an external QSPI flash. We planned to put our bootloader in STM’s internal flash and our firmware in the QSPI flash. We need to protect the internal flash (bootloader) for reading from the ext...
Reading in ADC on STM32H753
I am trying to run a simple program that can read in data from a potentiometer through ADC. The pot is connected to PF10 or A5 on the nucleo board. My code is below:When I run this it prints "Value is: 32767" once then stops. Because I am in conti...
Resolved! STM32H743 ADC with DMA for continuous acquisition and processing
Hi everyone,I'm working on projet which does the acquisition of signal continuously with sampling frequency is 25kHz. The length of acquired signal is about 1s (25000 samples), then some signal processing will be applied on this signal to obtain some...
STM32F429 Discovery Kit LEDs does not blink
Dear STM Community,I am a Fresh learner of STM32 technologies. I got myself an STM32F429 Discovery Kit.As expected, I tried to do Led Blinks on my board since it is the hello world of this technology.However, I couldn't turn on the LEDs on board. I c...
What is out put data rate of lis2dh and lis3mdl ?
i read data sheet of lis2dh and lis3mdl. i am using st linux driver to read raw data of accelerometer and magnetometer. Now when i set sampling frequency 1600 for accelerometer i get data of x axis at 40 ms. when i set sampling frequency 80 for ma...
USART1_IRQ HANDLER ISR is not getting executing after enabling RXNEIE is set in cr1 and setting priority in NVIC_ISER1 register in stm32f401re nucleo board.anyinputs?

Can't see the data using DMA and ADC
I'm using STM32F303RE, and I'm trying to sense analog values from different ports of the ADC using the DMA, but at the moment the application is running, I don't get any data. I tried to put an interrupt routine to see if the DMA is at least been cal...
