Hello, first of all I'm completely new with microcontrollers and I really don't know anything. This is my first experience trying out one. I'm a total noob.I'm using STM32F103C8T6 with STLink V2. I have 4 units of STM32 and 3 of STLink. I upgraded th...
Hello,I am starting a project using this eval board.I need to route octo-spi flash and ram (like on the eval board).Do you have information about the stackup used ? Altium files give me a stackup but I find it a bit weird :Cu1 is 42µm / D1 is core 10...
Hi,I read (here) that it's possible to use a Nucelo board's in-built ST-Link Vn debugger to program/debug a custom STM32 board. However, I have a doubt about this.Please can anyone tell me whether such an approach is possible? I have available two Nu...
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...
