My NUCLEO L496ZGP stopped working.

I was Displaying HSI on Serial Port using Alternate Functions, as soon i enabled the HSI i got the following error messege.Target no device foundReason: No device found on target.Looking Forward for help.Regards.

Resolved! STM32H7 UART DMA Receive unknown length of data.

I use STM32H753 and USART1 with DMA to receive data of unknown length (Min: 8 bytes Max: 512 bytes) from PC. Data will be sent in burst after every one second. My baud rate is 9600. So approx 1ms per byte.So, maximum, I'm going to get all the data in...

problems with timers and i2c

hello, i'm using a stm32f4 discovery to control a dc motor, for this i've used different timers for the different actions i have to do in this one, TIM2 is in charge of reading encoder, TIM3 is the pwm generator that goes to a H bridge, TIM4 i use it...

Unable to receive complete data into my SPI slave receive buffer?

I am using stm32h745zi-q board and I am working on the full duplex SPI. Here I aa using spi1 and spi4 . I used interrupt based at the spi1 means master side and I used DMA for SPI4 means slave side .Here I am able to get the complete data in the SPI1...

Resolved! USART with DMA circular buffer transfer only the first byte

Hello,I have to transfer the bytes received from UART2 to the circular buffer via DMA. The microcontroller I am using is STM32L010F4 with LL instead of HAL.When I send a sequence of bytes to UART2 I notice that only the first byte is loaded into the...

How can I attach a function to an interrupt on the SensorTile.box lsm6dsox sensor.

I have a interrupt that is generated from a finite state machine on the LSM6DSOX sensor. I have routed the interrupt to the INT1 pin. How can I attach an interrupt handler function to this interrupt so the function is executed whenever the interrupt ...

Resolved! AN4661 interface signal layout guidelines for high speed SDMMC operation states "keep the same number of via between data signals". Am I interpreting this correctly?

I am interpreting this to mean that each data signal (including CMD line) should all contain equal number of vias. For example if line D0 is routed to MCU and this trace requires 2 vias on its path to the MCU then all other data signals should also c...

Resolved! Clock recovery system CRS

Hello,I have problem with CRS (Clock recovery system) in STM32F091xx. I use HSI48 and I want to generate synchronization with LSE (32.768 kHz).How to set FELIM in CFGR register and TRIM in CR register ?Thank your for help.

How to use FMC in main while loop and interruption at the same time correctly?

Hello everyone. I am using STM32H743IIT with a sensor and two external SRAMs. The sensor is connected to the STM32H743x by SPI5 and EXIT2. The external SRAMs are connected to the STM32H743x by FMC.The sensor triggers the EXIT2 and in the interrupt fu...

PWM capture with TIMER (with DMA)

I have configured TIMER2 to capture PWM input (Basically PWM inputmode). Both CCR1 and CCR2 captures period and ontime of the PWM signal respectively. I configured DMA to captures these two registers CCR1 and CCR2 by configuring array of two 32bit bu...
