Hi All,I have a B-U585I-IOT02A board and the freeRTOS is flashed- https://github.com/FreeRTOS/iot-reference-stm32u5It has 2 digital microphones, but /iot-reference-stm32u5 does not include the BSP for audio.So I merged the audio BSP from STM32CubeU5 ...
Hello,Communication details (for now, the data transfer is only from master to slave): (i) NUCLEO-F413ZH is the master (ii) Arduino Uno R3 is the slave.(iii) DFF is 8 bit(iv) I want 2-line unidirectional Using HAL: The SPI communication worked and I ...
STM32F103C8Cube IDE 1.10Greeting,I tried to send data (count from 13 to 15 every 500ms) thru i2c1 using HAL_I2C_Master_Transmit.slave is pcf8574, scl & sda line pulled up with 3k3 resistor.usb scope shows master send correct address, but data always ...
Hello everyone,I encountered a weird situation concerning I2C on a project at work. We are using an STM32H743XIH6.We have an I2C device sending data, the I2C is setup with a DMA. Everything works fine until we have a physical disconnection of the I2C...
Current implementation of the SPI transmit HAL function handles incorrectly interrupts. Actually the interrupt handler is implemented like this:static void SPI_TxISR_8BIT(struct __SPI_HandleTypeDef *hspi) { *(__IO uint8_t *)&hspi->Instance->DR = (*...
In P687, right bottom part of Figure 248, it says "GRXFSIZ[31:16]", while P715 says that GRXFSIZ[31:16] is "Reserved, must be kept at reset value.".Besides, also in Figure 248, it says "GNPTXFSIZ", but there is no such register in this Reference Manu...
Hi everyone,I am working with STM32l452RC and trying to transmit 16bit data using CANBus line including several units (motor controller, Bms and other circuits). Our CANBus line works fine for a long time. Now I am trying to add one more device to ou...
Hi everyone,I am working with STM32F405 and trying to transmit 16bit data using CANBus line including several units (motor controller, Bms and other circuits). Our CANBus line works fine for a long time. Now I am trying to add one more device to our ...
I note that the XCube-AWS software employs FreeRTOS as a task scheduler. I'm using the STM32F769NI-DISCO development board to do some testing. That software is working out of the box. I can see the Ethernet handled as a task. I also see the USB CDC (...
