Hello all,I'm using STM32 F103CBT6 MCU on a custom board where MAXRS485 is used. Rx and Tx of the Modbus chip is connected to USART1 on the MCU.To receive and Transmit data I'm using UART in interrupt mode. The program also has 8 GPIO interrupts on m...
I created a button widget with stem win library. The button click is detected but button release is not happening. I tried using some demo programs there it is working. I have attached a basic program which shows when a button is pressed and released...
I have an stm32f407g.In the reference manual (in the ADC section) I found several terms I am afraid I have confused between them.I would like to explain my reasoning with an example and get your feedback if I said something wrong. -------------------...
Hello everyone,I'm trying to set up VREFBUF as an internal reference at 2.5V, but the configuration isn't working. I've seen there were issues with this (VREFBUF Enable Problem - STMicroelectronics Community), but even after rearranging the function ...
Hi, I'm using stm32f429 disc1 adc1 PA4 and GND to get the ADC signal, the voltage of the signal is 300 mV. The signal that I'm getting after conversion has some noise, But the same signal when seen through an oscilloscope has no noise. The noise or d...
Using the CubeIDE Rev 1.12.1, I have loaded an application and set a breakpoint in an STM32L562 uC. I am using a Segger J-Link Plus probe (does the same with ST Link V2) to debug. I know something has happened to the CPU from a code stand-point as t...
Hello ! I've got a problem because I tried to check the SDA and SCL pins like in the picture : Sorry for the paint picture (the oscilloscope was during classes so I don't have it right now).The output was all the time noises even thought the code wa...
Hi everyone,I am trying to implement a system that counts pulses that can be as narrow as 20 nanoseconds using an STM32F746 MCU clocked at its max 216MHz.The first thought was: "Can such narrow pulse even be detected by the MCU?"To confirm, and inspi...
Hi,I'm using STM32H743ZI with STM32CubeMX 6.9.2 and STM32CubeIDE 1.13.1.I added new STM32 project using the CubeIDE GUI - selected the STM32H743ZI device and automatically the project was generated, I opend the IOC file and enabled the ETH + LWIP opt...
I am working with STM32H747i-DISCO board and I configured ADC1 with DMA1 stream0 and ADC3 with DMA2 stream0 both with Cortex-M7 core as initializer and I created the MDK-ARM project using STM32Cubemx and compile the code in CrossWorks when I debug t...
