Hello ST Community, I have setup a SPI master and a SPI slave, both use DMA in Normal mode. The word size is 8-bits and the data size is 8-bytes. The problem is that the slave transmits messages which contains old data. When it should send:MISO: { 0x...

Hello, I am working on a motor control project that is to be driven battery-powered. This means that the DC current has to be monitored in order to avoid overloading the battery. I have made a Control Loop which takes in a DC Current reference as inp...

Greetings,The motor I am working on is low inductant ~0.1mH with a max speed of ~2500rpm. I am wrestling with noise on the measured phase current signals, which distorts the control loop and in the end results in bad control or 'Over Current' Fault. ...

I am trying to drive a 250W BLDC motor. I started profiling the motor, which looked promesing. I based a project on the motor characteristics, but haven't been able to drive the motor as well as the motor profiler did. I have used same drive frequenc...

I am facing issues while running a BLDC motor using the 6-step algorithm on the STEVAL-SPIN3201 board. The only modification I have made is to the Hall effect sensor low-pass filter to address noisy input signals.I am encountering the following probl...

When cloning or downloading the STM32Cube_FW_WB_V1.19.0 the examples comes with relative include paths (../)Opening the Compiler Include Paths looks like this: When copying a example project the resources should therefore be included as well. This is...

Sorry for the unclear communication and the inconvenience it has caused. I tried communicated the desired functionality through the sequence diagrams. I will accept @PPopo.1 s soultion and start a new thread.

The only purpose of the DEBUG pin is to show that there is plenty of time between the TxBuffer is updated in main until a new transfer starts. I know that I should monitor whether a SPI transfer is ongoing before I update the TxBuffer. I will handle ...

Thank you for your replies. @BarryWhit I do want to understand why the current setup isn't working. I am well aware that if I only call the HAL_SPI_TransmitReceive_DMA in the main loop (or in the ISR) it would work as expected.I have setup this code ...

Ideally I would implement sequential first and then concurrently. The first screenshot i posted from the logic analyser it showed that the TxBuffer was processed way before the next transation began. How can it be that I still see old data in the fir...
