I want to use my CY8CKIT-042-BLE to configue an SPI that will drive an external Sharp Memory LCD.  The Sharp must be clocked at a frequency between .5 and 1.0 MgHz.   And it must also have a 1Hz or so clock for non-polarization purposes.  Not having any luck with the (widely spread) documentation on how to make an SPI or PSoC 4 BLE system output a .5-1 MgHz clock or a 1Hz clock.  Any suggestions?

Use two TCPWM and configure it as PWM to generate pulses of a defined frequency and duty-cycle.

   

Feed them with an appropriate clock and connect the outputs to pin components. Quite easy, goes faster than it takes to write tis message.
