Hello,I am trying to route printf-like data streamed from the SWO pin of an STM32L432KB MCU to a Windows command prompt using a STLINK-V3SET/MINI probe. I need to do this while flashing new firmware or debugging. The SWO pin uses UART encoding at 2 M...
Hi ST tesam,When I use the HAL of STM32C031, I have some trouble about SMBus.Q1:When I use the SMBus of STM32C031 series. If I do not got the feedback from the slave, sometimes the SDA will pull down(similar to the yellow line show as below) and syst...
Hi Team, where we are trying interface ENC28J60 in STM32F407VG Microcontroller to use Ethernet, Is there any procedure to create a project in cube ide are any link related to this board how to interface ENC28J60 to STM controller. Best Regards,Gagan ...
Working on a product-based STM32F203, getting multiple ARM exceptions of all kinds, Bus Fault, Usage Fault, Hard fault, and Mem fault. The issue is I have a year-old debug Log for debugging purposes. I can't recreate any ARM exception to check the st...
I want to connect 2 Nucleo F103RB as slave (2 Nucleo slaves) to one master (PC for now) over Modbus (RS485). how can I do that? Please note I am new to STM32, so I have limited knowledge.P.S. I have connected one master (PC) and one slave (Nucleo) bu...
Hi team,I am currently developing a board with the STM32L476RET6. This project involves UART communication (UART4, PA0 and PA1), and I am concerned about EMI due to the fast rising and falling edges of the TX signal. To address this issue, I am imple...
Hi!I'm using Nucleo-f429zi board and my trying to configure it to read and write data over modbus RTU (RS485)and i'm using keil uvision 5 to program. I have referred some videos and post on how to configure STM32 and its USART port for modbus communi...
I am trying to figure out why the state of GPIO pins are changing after entering Stop2 mode. I've got an ADC chip connected with Reset lines being held high by GPIO pins configured as push-pull with pull-ups enabled. When the device enters Stop2 mode...
I’m using CubeIDE and I want to internally connect peripherals to the comparators. This doesn’t appear to be supported by CubeIDE, but I’m wondering if its still supported by hardware somehow.I’m using an STM32G4 and I see that COMP6 INP lands on PB1...
The maximum HCLK of STM32F407 is 168MHz, while the calibration value of Systick is 150MHz HCLK. What is the reason for setting the calibration value of Systick like this? Why not set the calibration value for Systick based on 168MHz HCLK?
