Hi all, I want to connect a digital module max6675 with thermocouple to a FX3U-14MT-RS485-RTC PLC. This is PLC from AliExpress *click* The problem is that the device I have has a spi interface. Is there available to connect SPI interface for a FX3U-14MT-RS485-RTC PLC? I have to admit I know very little about SPI. thanks
