SPI communication with X-NUCLEO-OUT02A1

[Zuffouille]

I order the X-NUCLEO-OUT02A1 and I work with a NUCLEO-F746ZG.

These two boards aren't directly compatible I know.

But they communicate with SPI, so I'm sure that you just can implement the communication with a bit of mapping with some breadboard wires.

It should works.

I saw that there is some library to use with other board but I don't want to install it. Because I don't need all that stuff, Ijust want to implement the SPI communication.

And in the HTML compiled program, nothing.

Impossible to find any documentation about the communication between these two boards !

Were can I find it ?

Welcome, @Zuffouille​, to the community!

As can be seen from the schematics, the ZIO connector is compatible to the Arduino Uno one used by the X-NUCLEO-OUT02A1.

Examples of communication can be found in the source code package X-CUBE-OUT2, which so far only contains drivers and BSP for STM32F3xx and STM32F4xx. However, it should not be too much of a problem to add the missing parts for STM32F7xx and other families.

Does it answer your question?

Ok thanks, i see

Now i have another problem.

I've implemented the SPI communication and i can transmit and receive the fault byte from the board.

But there isn't any led that turn on...

Here is the code that I add to my project. I didn't add the X-CUBE-OUT2 package.

// Communication with relay shield
uint8_t Iso8200aq_Board_SpiWriteByte(uint8_t *pByteToTransmit, uint8_t *pReceivedByte, uint8_t nbDevices)
{
	HAL_StatusTypeDef status = HAL_OK;
	uint32_t i;
	HAL_GPIO_WritePin(GPIOD, GPIO_PIN_14, GPIO_PIN_RESET);
	for (i = 0; i < nbDevices; i++)
	{
		printf("SPI TX : ");
		print_bin(pByteToTransmit);
		printf("\n");
		status = HAL_SPI_TransmitReceive(&hspi1, pByteToTransmit, pReceivedByte, 1, 1000);
		printf("SPI RX : ");
		print_bin(pReceivedByte);
		printf("\n");
		if (status != HAL_OK)
		{
			break;
		}
		pByteToTransmit++;
		pReceivedByte++;
	}
	HAL_GPIO_WritePin(GPIOD, GPIO_PIN_14, GPIO_PIN_SET);
 
	return (uint8_t) status;
}
 
void testSpiCom()
{
	uint8_t state1Relays = 0b11001100;
	uint8_t state2Relays = 0b11110000;
	Iso8200aq_Board_SpiWriteByte(&state1Relays, &spiRxByte, 1);
	HAL_Delay(5000);
	Iso8200aq_Board_SpiWriteByte(&state2Relays, &spiRxByte, 1);
	HAL_Delay(5000);
}

And here is the output console :

And nothing on the output also (i've measured the voltage).

What i'm doing wrong ?

Has the ISO8200AQ been fully initialised?

Have you enabled the ISO8200AQ via ISO_OUT EN before writing to the SPI port?
