network_wiznet5k.py SPI id

Open jay6621 opened this issue 4 years ago • 3 comments

The link https://maixpy.sipeed.com/en/libs/machine/spi.html#parameters clearly states that 'id' for SPI allowed is 0 to 3 but example here under Network folder - network_wiznet5k.py has id: 4 , How? what is the right data ? I would love to help writing or developing Ethernet support for Maix Dock. Any Help is appreciated.

4 is the same as SPI.SPI_SOFT

So, it is using software SPI ? How about using hardware SPI ? I couldn't find any pinout diagram for Maix Dock.

The documentation isn't so clear on this side. You have 4 hw SPI devices. SPI2 can only work in slave mode, but I read somewhere. maybe in the documentation, that the slave mode isn't implemented. SPI3 is reserved the the flash. SPI0 is the lcd, I think and SPI1 is the SD card, but also not sure. If I use SPI1 the SD card isn't available.

So there is no free hw SPI device for the network. Some interesting material can be found here.
