Hello, I encountered some issues while using SPI to control L6482:
1. My read/write SPI logic seems to have failed, unable to read/write normally. Is this a problem with my SPI timing?
This is the timing sequence for me to retrieve the status register.
This is the timing sequence for me to read the 0x15 register.![lcc1111_3-1735090550487.png lcc1111_3-1735090550487.png](https://community.st.com/t5/image/serverpage/image-id/96828iA3D572EE5064AF07/image-size/medium/is-moderation-mode/true?v=v2&px=400)
But their SDO pin has always been at a low level.
2. Regarding the control process of the stepper motor through L6482, I saw on <<an4290-l647x-l648x-and-powerstep01-family communication protocol microelectronics>> that it says run the RUN command first, then run GOTO, run SPEED and POSITION commands, and finally SOFTSTOP. Is that correct? I don't understand what SPEED and POSITION mean here?
