Linker file bugs in LWiP HTTP Server examples for gcc
There's some problems with the .ld files for SW4STM32 for various processors in the LWiP demo projects in the CubeMX HAL distribution files.For instance F7 version 1.16.0 746 and 767 nucleo boards, the RAM section overlaps the ethernet DMA rx and tx...
Resolved! Why doesn't it enter when I press the button to enter standby mode?
I sleep at the time I set with rtc on the stm32f103c8t6 microcontroller. I wake up with the alarm I set. No problems so far. I want to sleep when I press a button. But when I press the button, it sleeps, then wakes up immediately and sets the alarm t...
Clock precision on a STM32L476
Hi all, I need to drive the ADC with TIM1 at 4MHz, drive by an external event.I want to know the clock precision on this timer. For the moment I use HSI16 and the PLL to have 80MHz on APB.I also have a LSE for the RTC.but what is the precision. I nee...
LPTIM match interrupt discrepancy on STM32U5
Hi,We are working with STM32U585AI processor. Our software is based on an RTOS and we are using LPTIM to generate OS ticks.Our system runs from either PLL@160MHz or HSI@16MHz depending upon system load. LPTIM is fed directly from LSE@32768Hz.We are f...
Flashing Issues
A strange issue is observed, i am able to flash using STM32 CubeIde and shows flashing successful, but when run command using debugger the code does not execute, it stays at while (1). Any possible reasons why such behavior happens? Please advise.
Resolved! CAN-FD stops mid-frame for higher data rates
I'm trying to setup a CAN-FD example with data rate switching (1MHz nom, 8MHz data) on an STM32G0B1. It seems to work up to 4MHz, but when I decrease my divisor to get to 8MHz, the CAN frames just stop after the arbitration. Here's my init code that...
Nucleo Board F746ZG, USART connection with ROS, issue: Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino
My Demo I need to establish a USART connection between my board and ROS1. The python code I run in ROS environment is in the package "rosserial_python" and it is called "serial_node.py". I followed this guide ( https://www.youtube.com/watch?v=cq0HmKr...
