I have used this method many times on this board (Nucleo-H743ZI) to transmit printf() to usart3 using the following: int __io_putchar(int ch) { /* e.g. write a character to the USART3 and Loop until the end of transmission */ HAL_UART_Tra...
Hello, good afternoon.I have two Nucleo boards STM32G071RB that I have written an I2C interface for. It is basically a command interface, where Master sends a command, and polls the slave later to get the response. I have tested my application thorou...
I am using a Nucleo-H743ZI as a SPI slave device for the following coms method: Master Pulls SS low, Delay 1ms. Master Transmit/Receive 1 Byte (Wait for high busy line) Slave RXP Interrupt-> Lower Busy Line Slave Transmit/Receive 1 Byte Slave Process...
I am having issues with my slave responding to my master. I am trying to lessen complexity by only using RXP on the slave, without TXP. The slave (Nucleo-H743ZI) responds one byte late.On the CS interrupt I send 0 for the first byte and enable RXP.*(...
I am trying to get the Ux_Device_CDC_ACM application working on the NUCLEO-U5A5ZJ-Q development board. I see the VCOM port activated on the PC but how do I get the UART port? It appears that the application writes from the UART port to the VCOM por...
Hi All!I'm trying to use USB high speed in STM32h723 with an external phy usb3300.I started the program from the CubeMx Ux_Device_CDC_ACM which uses the internal phy.I modified the clocks and the USB module to use an external phy USB3300 and so far i...
Hello Techies, We are using STM32H743, we would like to run mcuboot on stm32h743, but we haven't find the example for stm32h7xx devices, Is there any specific reason not to provide mcuboot example for h7 devices?
I am trying to read multiple channels of ADC (like Temperature sensor channel, Vbat channel, Vrefint ...) using the interrupt method, but I am not able to read all the Channel readings , only the readings of first channel is being reflected for all t...
Hello everyone,I have setup my stm32 to use interrupts and have enabled them to work on spi1 and all 4 i2c ports. The relevance of the i2c ports is that they run continuously and may call the interrupt service routine while the spi one is being calle...
Friends, which algorithm do you use to control the LEDs in this structure? I need your ideas. I have prepared a table of the LEDs' turn on order.
