Hi, there's something confusing in the schematic for the H755 Nucleo's reference PCB schematic (MB1363).I don't mind adding that I'm getting a bit tired of confusing and contradictory documentation from ST Micro.The description of changes when config...
Hello, I'm trying to use this nucleo board with the camera DCMI interface. This camera has operation condition between 2V8 and 3V1.Currently, I power the camera with a external source of 2.9V but the nucleo board is in 3V3.Is there a solution to powe...
Hi all.Am working with the STM32H573-DK, trying to get the ethernet connection working with FreeRTOS & LWIP over DHCP.I can see with Wireshark that it's sending the DHCP discover out ok & the DHCP server is responding with an offer but the code seems...
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 ...
