I have an STM32G4 board that is to function as a virtual COM port via USB. This is my first attempt at implementing USB. Within CubeIDE, I enabled the USB feature and configured a middleware device for the virtual COM port. I’m not seeing the PC rea...
Problem : GPIO PB7,8 is pull up in reset state.Reproduction: After Clearing Reset (Reset Goes low) the voltage on PB7 and PB8 goes high. uc is erased. We have external pull down connected to those pins (100k), but the signal stays at 2.5V Could you...
Hello,I am currently trying to setup a timer to measure time in between two pulses. I have managed to get it working with the code below but the issue is that I get very imprecise readings on the frequency. I get an error that is hovering around 1-1....
Hi All,I am using a STM32U575QI and I am wondering if it would be possible to create my own boot loader and then split my FLASH into 2 sections. I know I can get the boot loader application to start at address 0x0800000 and I have offset the vector t...
Posted on September 01, 2017 at 16:21Hello,we want to set path for 'Mcu and Firmware Package' to path relative to CubeMX project directory. Rationale - in case you store CubeMX and other source files into VCS, the absolute path to the Firmware packa...
Sorry, Google Translate changed my previous post to Polish. That's probably why no one answered me.Now the post is correct. This code was generated by STM322CubeIde UINT MX_USBX_Device_Init (VOID *memory_ptr) { UINT ret = UX_SUCCESS; UCHAR *poi...
if i load a 95KB code in stm32l44kcu6 controller ssd1306 display is hanging
I am using a STM32L431KCU6 microcontroller and reading data from I2C every 90ms. I would like to implement a sleep mode to achieve lower power consumption, I am using timer6 which generates an interrupt every1ms for system run time. I was thinking I ...
I am trying to use DMA with PWM data on STM32 I need clarification on few parameters setting and facing few issues.Q1. While configuring DMA for PWM data in tha CUBE MX, there is a option for increment Address and selector for Peripheral or Memory.Wh...
Hi i want to hard reset my MCU once after 5 minutes is there any way to implement it i know i can do this by NVIC_SystemReset(); but i just want to do it once after power on the mcu
