Hello everyone,I am trying to receiver a DMX frame using STM32 UART interrupts. I'm trying to receive the data byte-by-byte using a state machine logic. The problem I am facing here is that none of the debug LED code to toggles the LEDs when the prog...
I am trying to read ADC from two channels without using DMA. For that I use this code: /* USER CODE BEGIN 0 */uint16_t ADC_VAL[2];void ADC_Select_CH1(void){ ADC_ChannelConfTypeDef sConfig = {0}; sConfig.Channel = ADC_CHANNEL_0; sConfig.Rank...
Hi all,I am using an STM32F429 discovery board to develop a DSP platform for making some sound effects. I have I2S streaming and passing through, and I have SDRAM configured where I can talk to it and even transfer my buffers on and off it.Where I am...
The below oscilloscope capture appears to show that disconnecting the ST-Link from the Windows laptop adds 80 ms to the NUCLEO startup, until the first UART packet is sent. If that is correct, what can cause this delay?Thank you in advance for your f...
Hi,I'm trying to set up a USB host using a Nucleo144-F767ZI, which should exchange data with a Nucleo64-F103RB through USB. Since the Nucleo64 doesn't have a USB interface for the F103, I want to utilize the VCP (Virtual Com Port) of the ST-Link on t...
I am trying to bring up the MX25UM51245G NOR Flash connected to OctoSPI 1 on a STM32U5xx development board. I have implemented most of the actions specified in AN5050 to set up this NOR Flash.Since my use case does NOT require the ability to have the...
I try to setup a SPI COmmunication to do some "cross-communication" for Safety Reasons.So in my test setup, i read characters from UART, send them via SPI to the Slave, the Slave logs them via UART and ackknowledges them through sending an "39".Sendi...
I am trying to read and write to the MT25TL01G on the STM32H747I-DISCO board via the QSPI interface during runtime. I followed https://community.st.com/t5/stm32-mcus/how-to-add-a-bsp-to-an-stm32cubeide-project/ta-p/49812 to add the BSP to my project,...
Hello everyone!I'm trying to use ADC1 and ADC2 with DMA from a NucleoBoard STM32H732 under STM32CubeIDE. I am following the tutorial presented here:https://www.digikey.de/en/maker/projects/getting-started-with-stm32-working-with-adc-and-dma/f5009db3a...
I have completed an initial version of embedded C-code using the NUCLEO-F103RB. As a next step I plan to 'break off' the ST-Link portion and use the remaining NUCLEO board for building prototype hardware.Question: is there an Application Note or best...
