Hello,I have a question regarding doing a firmware update via the USART-pins and IO-Link.Would it be possible to use a IO-link master module to sent an update to the L6362A which translates it to 3.3V UART for the STM32G0B1KEU6 we are using in our cu...
We have a new revision that has a significant population of boards with this intermittent power issue. steps to reproducepress power buttonpower applied to the MCU the MCU only prints a single debug message, then haltspress reset: device works normal...
Hi,I used PA12 & PA11 as input gpios(pull-up) in STM32U595VJT6Q ,read the pins are always '0'.The IOs connected NOTHING.I reference RM0456 : I config USBPWREN and VDD11USBDIS bits used the HAL functions before GPIO_Init():HAL_PWREx_EnableUSBHSTrance...
Hi, Community,I'm trying to understand the OCTOSPI peripheral on my STM32L4P5. I'm new to STM32, but old in embedded. Particularly, I need to know/affect the idle level of the data line of the OCTOSPI. I thought that the last transmitted bit would re...
Hi! I'm looking to implement a phase vocoder algorithm on an STM32F4/STM32F7 and I was wondering if anyone has already done this and can provide suitable resources?Thanks!
Hello,I am using "NUCLEO-H743Zi2" eval board. I am using it for UART communication. I had configured UART4 in it as following;PA0 as UART4_TXPA1 as UART4_RXWhen I tried to transmit, it is not transmitting more than 2 bytes. While receiving, it is not...
Hi,I'm attempting to set up an STM32U575 as an I2C slave. (The master is a F301)My problem is that the slave only receives one byte, and then proceeds to disregard all of the following data.I have set up a switch that turns on an RGB LED, depending o...
Hello im Khoi. i get big trouble with stm32l431rct, when i using freeRtos . Task1 i using spi comunication . Task2 i get ADC DMA . When i disable Task2 program no problem. But i enable task2 get problem spi hardfault-Handler . Excuse me :((
Hi during development of program I found weird behaviour. I am using STM32G030C8T6 MCU. I am trying to connect external device using HC-05 bluetooth module. In my project I also connect with devices using MAX3485 module for RS485 communication. I wro...
I have a breakpoint in the interrupt, but when i debug this point, the scope does not show the signal (red) as expected.It should be high and not low, as you can see in the picture.
