STM32F303 UART TX with DMA stops after two bytes under high traffic
Hello,I am experiencing an interesting problem on the STM32F303VET:UART1 is used to receive and transmit messages (460800 Baud), DMA1 Channel 4 is used for memory to UART TX buffer transfer, DMA1 Channel 5 for UART RX buffer to memory transfer.Under ...
I want to do ADC on 5 channels with stm32f722ze, but cannot obtain data on the latter 2 channels.
I want to do ADC with 5 channels using STM32 Nucleo-144 development board with STM32F722ZE MCU.I can collect data by DMA, but I can only get data from in0~in2.Finally, I want to get ADC data from 5 channels at 1kHz using timer interrupt.This is my fi...
After adding BL and changing the FW flash position, core communication doesn't work
Hello!I have developed a firmware for the STM32H745 where I have communication between the two cores. I am using a specific ring buffer library and the semaphore method. Meaning:First core gets the semaphore, puts something into the shared memory, re...

How to use Hyperflash/Hyperbus with STM32H562
Hello,I am trying to use infineons S26KL128SDABHI020 HYPERFLASH memory with a STM32H562VI microcontroller.For now I am just trying to do a simple write and read manually to make sure that everything is working.I use the OCTOSPI module with Hyperbus-m...
How to use multiple timer capture Interrupt in stm32
Hii....i AM WORKING ON stm32l475rg MCU. i want to use two different timers for measurement of two different PWM inputs signals. for this one i am using capture call back function but i am facing problem to measure duty cycle of both channels at a tim...
Resolved! JTAG signals on STM32L433 [RESOLVED]
Hello,for the project I am developing I am using a STM32L433.We have connected a motor encoder signals to PA15 and PB3, that are CH1 and CH2 for timer1 TIM2 configured in encoder mode.We used CubeMX to configure the HW, and that worked perfectly for ...
I3C TxFIFO target limit
Hello, I am working with the STM32H503 board and using the I3C TX FIFO in target mode for communication. However, I have encountered an issue where, when transmitting data, the FIFO is only sending 8 bytes in total. I would like to configure the TX F...
Resolved! documentation error AN4777
In the first page of AN4777, the RM0411 is listed as the reference document for STM32L4x6. There is no link to the document and i am unable to found it. Also in STM32L4x6 page, the reference manual is named RM0351 instead of RM0411.
