In AN2606, it goes into pin specific detail about the pins when look at your specific chip line. Does this mean that I am limited to those specific pins in order to use the bootloader and that I cannot used an alternate assigned pin?
Hi, I am using STM32H743 nucleo board on one of my design. On my board I have installed nucleo board on board to board connector. For FDCAN interface we are using TCAN3414 transceiver IC. Our bit rate is 1MHz and data rate 2MHz for FDCAN communicatio...
What I want to achive:I2S Audio Output on the included Arduino Header of the STM32F746G-Disco Board to drive a MAX98357A class-D amplifier.PB4 I2S2_WS on Ardunio D3 PI1 I2S2_CK on Ardunio D7PI3 I2S2_SD on Arduino D13To ensure that no configurable sol...
So, the situation has been pretty uncomfortable and frustrating.I'm trying to implement the code to make the USB-C on the STM32U5A9J-DK work so that my PC recognizes the board as a Device.I first started to try to implement it with my currently runni...
Hi, I have created a program to send UDP using NetXDuo on a Nucleo-H755ZI.I used the URL below as a reference.Creating a dual IPv6 & IPv4 NetXDuo UDP application for STM32H7 using CubeMX I checked the operation in debug mode and could see that it is...
Hi,I am connecting ESP32 with STM32G474RET6 Nucleo board via SPI. I have configured SPI in DMA mode to transfer data. With NSS pin enabled for chip select I can see the pin remains low always during transmission of data and also in idle. So that I co...
My project is using a GPIO to enable/disable a buzzer on a software timer. This boils down to a call to HAL_GPIO_WritePin(), which does GPIOx->BSRR = pinmask (0x80 in this case) to enable the buzzer. This works as expected most of the time. There ar...
Hi, The SPI communication between an ESP(Master) and the STM(Slave) is failing when i configure the SPI clock at 10MHz.I have STM32F429ZIT6 DISC1 board and i have used SPI3 as slave, the SPI3 is on the APB1 bus which is configured at 45MHz PCLK.The c...
Hello!I just received some custom PCBs with the STM32H747BIT6 MCU, but I’m having trouble connecting to it. I’m using a J-Link V12 and initially tried to establish the connection with jlinkexe. It correctly detects the voltage, but when attempting t...
The pins for USART3 are listed as PD9 and PD8; however, these are not available on the microcontroller.What are the correct pins? Similar to posts:https://community.st.com/t5/stm32-mcus-products/stm32h5-bootloader-uses-usart-pins-that-do-not-match-ro...
