In your last webinar about the 6.2 release of the STM32 Motor Control SDK I asked about this and I got the next reply:No native support is planned for SPI encoders. However, we have many customers doing this very thing. The FOC Scheme needs position ...

It would be very useful to be able to use an external encoder using any serial protocol.I'm working with a RLS AksIM-2 with SPI, and I don't see an easy way to integrate this encoders with the code generated by the MC Workbench.As at the moment the o...

It would be very useful and I think relative easy to implement: To have an alternative pinout view but instead of the the IC, a view of the nucleo board with the morpho and arduino connectors.Something like this but interactive: https://os.mbed.com/p...

I'm using a general-purpose timer to generate low level pulses, configuring one channel as PWM. The problem is when I disable the channel, the signal goes low, and I want it to remain high.I played with the OCPolarity and PWM modes 1 and 2, but only ...

Hi,I´m trying to transmit (send only) 3 bytes with the SPI using interrupts, and deassert the chip select line from an interrupt routine that should be triggered when the transmission ends.The line 11 (// more stuff here ...), doesn't run immediately...

Thanks for the answers. What @AScha.3 suggests is only for advance timers and I'm using a general purpose one (I'm regrating this, but the PCB is already made)So I will reconfigure the pin as gpio output and change the level before stopping the time...

To clarify, my configuration is STM32 as master with several slaves and by "end of transaction" I mean just after the last clock pulse. I was expecting an interrupt there, when is safe to deassert the CS for that slave and the SPI is ready to be used...

can you please elaborate? The only RX related flag I can find is RXNE (Rx buffer not empty) and I don´t see how to detect the end of the transaction based on that.

Done it, and works for me. Thanks!
