GPIO Toggle Frequency in EZ-USB FX3 - KBA83988

Version: **

 

Question: How can I increase GPIO toggle frequency if I am using CyU3PGpioSetValue() and CyU3PGpioGetValue() with an EZ-USB FX3 device?

 

Answer:

Using CyU3PGpioSimpleSetValue() instead of CyU3PGpioSetValue() will increase the maximum output frequency. A lot of conditional checks are removed when you specify that the GPIO is simple.
