Hello,I'm looking for a board that provides all program/debug signal on a header while allowing to disconnect on-board MCU.I've looked at a few NUCLEO boards - only JTCK, JTMS, NRST, SWO are exposed to a header (with possibility to disconnect on-boar...
I wrote a simple program using interrupts: Turns on the LD2 the diode if signs "O", "N" and enter are received respectively, turns off if "O", "F", "F" and enter are received otherwise (Im passing only the parts where I made changes :( /* Private inc...
Hello,I am working on a project with a Nucleo-G431KB. I am using UART1 to receive GPS data (LEA-6S module, 9600 baud, 3.3V) on pin PB7 (RX), and I send data to a LoRa module (Ebyte E32868T20 module, 3.3V, 9600 baud too) on PB6 (TX).I configured UART...
Hi, guys, I've bought STM32H745I-DISCO board to make an EtherCAT master, so I successfully employ EtherNet controller, USART3 for debugging but SPI2 has a problem. (I'm mostly novice fir H745) I decided to use SPI2 for communication with exte...
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...
Hello, I have seen in the post That many users had a problem with the LDO power supply for STM32H757ZII wanted to ask, can you confirm that I have a correct implementation of the power supply for LDO?
hi im using stm32g474vet6 mcu , im using spi in dma mode of both tx and rx and made dma in circular mode.what happens means when i start a first tx or rx itself spi clk is coming continuously. what to do , it is due to circular mode.if (send_spi_cmd ...
I m trying to communicate through USART with my NUCLEO-L476RG but the STM console is displaying nothing. I have created a simple project:I m overriding the __io_putchar function:int __io_putchar(int ch) { if (ch == '\n') { uint8_t ch2 = '...
I am making a stm32f411ce board and I want make sure everything works because it's very expensive to order a pcb in my country. I want to use components like Hc-49 8mhz crystal(and dt-38 32.768khz) oscillators with ceramic PTH capacitors, the only sm...
