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...
When the STLINKV3 is used with the additional connector board (MB1440) the lower back can no longer be attached. This means that the LEDs on the top are no longer visible. I have designed a 3d-printable lower cover that remedies this :I have also mad...
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...
Hi everyone,I'm experiencing an issue uploading a simple onboard LED blinking program to my STM32H755ZIQ board. Every time I try to start a debug session, I get the following error:STMicroelectronics ST-LINK GDB server. Version 7.9.0Copyright (c) 202...
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...
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?
I got my custom stm32F746 PCB Working! It is based on the STM32F746G-DISCO. So, for the first revision I used the same capacitive touch lcd used on the Disco. So that all works! But I need a resistive lcd, so I designed in a TSC2046IPWR controlle...
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 = '...
