    PSOC4 SPI Using

      Hi All! 


      I am using the CY8C4126AZI-M445 as MCU. I will control 31 capacitive sensors and I will drive to led display also. So, I have to optimize pin using.


      For this reason, I plan to use HC595 ICs to drive display via SPI. But I won’t use MISO pin in our project and I don’t want to assign any pin for MISO of SPI. When I try don’t assign, after build operation, complier assign automatically. What can I do ? PSOC4 SCB Module(Ver 3.10) has not bidirectional option for SPI. Could you guide to me what can I do use SPI module with only 3 pins ( MOSI,SS,SCK) ? 


      Thanks in advance
