I am developing the board using STM32H7R7L8H6H. So in our design we uses multiple interfaces like TFT LCD RGB888, Ethernet(RMII), RS485, Wi-Fi-BLE module, External Flash and PSRAM.So for better signal integrity, can you please provide impedance and l...
I have a "NUCLEO-H723ZG" dev board. My current configuration is to power the dev board by 3V3 (CN8 pin 7 or CN11 pin 16), with all jumpers from the "PWR JP2" removed, as according to section "6.4.5 External power supply input from 3V3_EXT (3.3 V)" of...
Looking for some input for selecting an lcd for my custom stm32F764 application.Currently I have the LCD that came with the stm32F746G-DISCO board working with my custom board.The "DISCO" lcd is 4.3: capacitive 480x272. I need a 5" resistive LCD. I...
I have a Nucleo 32 board with STM32L432KC. I am using Power Profiler Kit II to measure the power consumption. I connected PPK Vout to Nucleo's 5V (pin 4 on CN4), GND to GND and the PPK is set as a source meter.Program on MCU is running for 2s in RUN ...
Hi, I've been trying to receive 5 bytes of data from a master MCU using SPI in slave mode.I have a timeslot control signal, and on each falling edge of that signal, I need to receive 5 bytes from the master.The timeslot control signal consists of one...
Hi all,I'm running into an issue when trying to deploy a model from to my STM32N6 board.I am following this guide: https://github.com/STMicroelectronics/stm32ai-modelzoo-services/blob/main/object_detection/deployment/README_STM32N6.mdrunning script:p...
I have made an project from touchgfx and opened it from subeide.The project is loading normally and i have overwritten the write function:/* USER CODE BEGIN 0 */ int _write(int file, char *ptr, int len) { int DataIdx; for (DataIdx = 0; DataI...
Hi STM Community,I'm trying to use the X-NUCLEO-LPM01A board to measure the current consumption of an Arduino UNO during simple blinking states.Setup Description:Power output is taken from CN14 (OUT and GND pins) on the LPM01A.These lines are directl...
Hi, i'm currently working on the STMH747I-Disco board, and integrating the STEVALSMKI227AA, and within using the LSM6DSV16X IMU sensor fusion to get the game rotation vector data via FIFO. The problem is that we are ready the status of the fifo 0x00 ...
HiI'm trying to sample a sine wave between 400 and 500 kHz with the Nucleo H723ZG. I'm using the 16 bit adc 1 with following configuration:sampling rate: 2 MSpsT_sampling: 16.5 clock cyclesf_adc: 50 MHz (from PLL2P: 100 MHz)DMA circular modecontinuou...
