Regarding the cause of HardFault_HandlerHardFault_Handler occurs at a specific timing in our software.I was able to determine which process was causing the problem by looking at the call stack, but is it possible to investigate the cause further by l...

Regarding function calls when performing SPI communication in half-duplex mode.We would like to develop a product that performs SPI communication in half-duplex mode.Are there any sample programs in which the slave side transmits and the master side ...

We are trying to develop a device that uses SPI communication (Receive Only Master).Are there any sample programs for SPI communication (Receive Only Master)?Which should be executed first: "Receive Only Master HAL_SPI_Receive" or "Transmit Only Slav...

We are trying to develop a device that uses SPI communication (Transmit Only Slave).Are there any sample programs for SPI communication (Transmit Only Slave)?What should be the trigger for calling HAL_SPI_TransmitReceive? Master's CS?

This is a question about Receive Only Master (SPI_DIRECTION_2LINES_RXONLY).I was able to output the waveform shown in the attachment using Receive Only Master.However, no data is being received(tmp). Why is this? The process is performed in the foll...

Thank you for your response.They are very helpful. And we are very close to realizing it.it is really helpful.Please tell me one more point.I would like to change the SPI Mode to “Recieve Only Master” and “Transmit Only Slave” from this state.I thoug...

You are certainly right.However, there is a reason why I am posting my question here and hoping for answers from others.Because I am not fluent in English, I cannot provide details.Basically, What I want to do is the opposite of what DGast.1 wants to...

”slave must be started first.”I see. That's how it was. Does this mean that "Transmit Only Slave" cannot be achieved with a MUC program?Is there any way to achieve this by combining the following APIs?・HAL_SPI_TransmitReceive・HAL_SPI_Transmit・HAL_SPI...

In the future, these will be connected to separate devices.The spi2 will be connected to the slave's transmitter device and the spi4 to the master's receiver device. So we are using two SPI peripherals.↑Is this correct as an answer?Is that what you m...

I forgot to point that out. Sorry.The reason for the two transfers is that the customer has requested that the pins used for spi2 and spi4 be separated.spi2 is the master receiving pin, and spi4 is the slave transmitting pin. Also, the spi2 clk line ...
