g_spi0. The SPI HAL module can support a transfer driver, whereas the data-transfer controller can be used to transmit and receive data between the hardware peripherals and data buffers in RAM (rather than the CPU performing the transfers). By default, a transfer driver is added for both transmit and receive. SPI읽기 동작시 바이트 단위로 잠시 쉬는 구간이 발생하는 것이 칩의 원천적인 특성인지, 혹은 제공되는 라이브러리 함수인 HAL_SPI_Receive() 에서 의도된.

STM32 + HAL + FreeRTOS Part III: SPI (blocking) Serial Peripheral Interface (SPI) is quite widely used in embedded systems for connecting all kinds of ICs - sensors, memories, screens, you name it. It seems to be somewhat less popular among the beginners/Arduino crowd than I2C, because of relatively more complicated setup. General Description. High level interface for interacting with the Quad-SPI interface. QSPI is an SPI-based communication interface, often used with external memory devices. The QSPI driver supports sending and receiving commands to/from from another device via a single, dual, quad, or octal SPI interface..

我正在使用STM32L476RG板和HAL SPI功能: HAL_SPI_Transmit(&hspi2, &ReadAddr, 1, HAL_MAX_DELAY); HAL_SPI_Receive(&hspi2, pBuffer, 4, HAL_MAX_DELAY); 我需要以最大速度从加速度计的缓冲区接收数据,但是这些功能的延迟存在问题。如您在示波器屏幕截图中所见,在几微秒内什么都没有发生。.

Best Answer. With a quick glance I see two potential issues. 1. You need to put the HAL_UART_Receive_ITinside the super loop. 2. The IRQ handler needs to be kept short. What you want to do is put the code in the HAL_UART_RxCpltCallback function which is.

I also attempted using HAL_SPI_Transmit() and HAL_SPI_Receive() separately instead of HAL_SPI_TransmitReceive(), but the same issues still appear. Also, I would like to use HAL_SPI_TransmitReceive() on both to verify on the Master and the Slave that the devices are communicating properly.Any help would be greatly appreciated. Thank you!.

Re: BMP388 MULTIPLE DEVICES USING SAME SPI BUS. Hello Honoju, I suggest you could do a test first. 1.spi master was connected to BMP388, read BMP388 chip id and capture SPI waveform by logic analyzer. 2. spi master was connected to BMP388 and your other spi slave device, read BMP388 chip id and capture SPI waveform by logic analyzer.
