Hello all,I've spent several days trying to ping my STM32H735 discovery kit with FreeRTOS and LWIP, to no avail.I've followed this tutorial as a starting point: https://community.st.com/t5/stm32-mcus/how-to-create-project-for-stm32h7-with-ethernet-an...
I have purchased STM32F769 Discovery Kit. I'm new to this board usage. I tried an led blinking example using STM32CubeIDE. After Debugging the code I lost the factory default code and now nothing is showing on LCD display.Is there a way to get back t...
Hi,I am using STM32f107vct6. I want to create generalized GPIO function which can set gpio mode. I am using pointer to access peripheral registers. I have tested following1] Configured gpio using structures which are available in library(i.e. GPIOA...
Hi!I want to use STM32 U5 for communication with smart cards. USART is configured in a smart card mode, but I don't know how to read ATR, send APDU commands. Is there existing firmware for this use case?Can you give me advice which firmware can I use...
Hi, I'm trying to jump to a FreeRTOS app via a bootloader that i made. I'm pretty new to this. I know there is a lot of similar topic on the internet but none of them fixed my problem. When I try to jump to my FreeRTOS app with my bootloader, nothing...
Hi all,I'm making a clock and I wanted to update the display every minute (I do not display seconds) so I thought I'll set the alarm mask for minutes only but that didn't work. I read here that the RTC is more meant to trigger an alarm at specific ti...
Hi,i am using a STM32L010K8 MCU and i want to wake up from stop mode when a RTC-Wakeup interrupt occours. Here in this example i set the RTC wakeup interrupt for 30 seconds. Without entering the sleep mode the RTC IRQ works fine. But if the MCU enter...
Not getting expected responses from motor according to ST manual. @Enrico Poli maybe you knowIs there something wrong with our Modbus packets or is what we are seeing correct and the manual is wrong? The answers here seem OFF TOPIC and cause confusi...
Is there any known quantification for how the calibration improves the accuracy of the ADCs?
Hi, I have a problem entering Stop Mode 2 with STM32L451CCU6. My current consumption is around 600 uA, while expected should be much lower. What can cause this problem? Here is the code: use cortex_m::asm; use cortex_m_rt::entry; use stm32l4xx_hal::...
