UART Interrupt callback calling only when running in debugging mode using Stlink-V2 Debugger
Hi, I am working on STM303CBT6 MCU custom design board, USART3 Interrupt callback working fine when program is running in debugging mode.If program running in Normal mode without debugger, USART3 Callback function not calling.Note, MCU BOOT0 pin is c...
Setting up UART 1 on B-L475E-IOT01a using bare metal (Newbie)
I can see an output in my serial monitor if i am using CubeMX and CubeIDE but with baremetal in Keil, I dont understand why i am not seeing any . I have a B-l475E-IOT01a board with me, and from the schematic I can see both UART1_TX and UART1_RX conne...
UART-1 working code reads NULL
Hi clive I have interfaced UART DATA device(sender) and NUCLEOF401RE(receiver) I have set the proper BAUD RATE 115200I am using UART-1 to receive dataI generated the code in the IDE and first tested for transmit functionality and it works fineI took ...
STM32F4 wake up from stop mode with UART
I am using STM32F407VG MCU (STM32F4 Discovery board) and I want my MCU to wake-up from STOP mode when it receives a message from UART. I had to adjust some things manually because the STM32CubeMX is unable to set UART Rx pin as an GPIO interrupt pin ...
Resolved! I have an product using a STM32l486. It uses USART1 with transmit and receive DMA to communicate over a serial port. Serial port packets are all the same length. My application works in run mode, but not in sleep mode.
I can send and receive packets in run mode, but I never get a RX DMA interrupt when in sleep mode. I do not have any interrupts enabled in the USART hardware, and do have DMAR and DMAT enabled. Any ideas on what might be missing?Thank you.
SPSGRF-868 configuration, SPIRIT1 VCO calibration not working

Write time-out on STLink UART
Hello,I am using an STM32F072 Nucleo board. I use the STLink USB-to-UART bridge to communicate with the MCU.From time to time, the STLink UART on the PC gives a write timeout. I cannot reproduce this readily, it does not happen often.The COM-port sti...
How to configure two DMA channels (ADC and UART)
Hi I'm using STM32cubeIDE and I use two DMA channels,DMA1_Channel1 is for ADC1 and DAM1_Channel5 is for USART1_rx.USART1 is using for RS485 communication. HAL_ADC_Start_DMA(&hadc1, &adcVal[0], 8); HAL_UART_Receive_DMA(&huart1, &rxBuffer[0], DMA_RX_BU...
