you are unfortunately right , no SCK = no SPI it is a shame , but it is advertised so you have to do SPI manually , or chose another MCU the only thing one could do with MOSI pin is to generate one wire command signal , like WS2811 (but not sure as never tried it)
I am looking at the SOP16 variation of the ch32v003. It says everywhere that it supports SPI. Although I see both the MISO and MOSI lines, the SCK pin is not broken out in this package (PC5). Has anyone used this package / know what's up with that and how one can use SPI without SCK? Both in the smaller as well as the larger datasheet it seems it is not configurable to a different port. Help appreciated!
