Zephyr SPI Codes Translation for The STMCubeIDE

[AE104]

Hello,

I am working on the SPI interfacing with STM32F4 microcontroller. I found an application which was written Zephyr. My aim is translating that code in to STM32CubeIDE format. Could you help me on this?

Here is the code,

static u16_t tx_buffer[1];
static u16_t rx_buffer[1];
	const struct spi_buf tx_buf = {
		.buf = tx_buffer,
		.len = sizeof(tx_buffer)
	};
	const struct spi_buf_set tx = {
		.buffers = &tx_buf,
		.count = 1
	};
 
	struct spi_buf rx_buf = {
		.buf = rx_buffer,
		.len = sizeof(rx_buffer),
	};
	const struct spi_buf_set rx = {
		.buffers = &rx_buf,
		.count = 1
	};

Thank you,

assert(tx_buf.len == rx_buf.len);
HAL_StatusTypeDef st;
st = HAL_SPI_TransmitReceive(hspi, (void*)tx_buf.buf, (void*)rx_buf.buf, tx_buf.len, timeout_in_ms);
 

And, of course, you need to call HAL_SPI_Init before, with suitable settings.
