looking at the STM32F103REY6 chip on the SPWF01SA, it has 3 SPI's. Are all 3 of these available to be programmed (I don't see them mentioned in the datasheet) or is it possible to use one of the SPI's MOSI/MISO,SCLK pins and then just use 3 separate GPIO's for the chip select CS pin for my 3 slaves? I need to be able to run 3 SPI slaves, a 20x4 LCD screen and 3 triac relays thru optoisolators. Is my SPI config possible on this chip/wifi module to get what I need out of it plus the wifi features or do I need to run another MCU along side this chip to do all this?
