I am trying to design a USB to SPI converter with 24 data bits per word. How can I increase the number of data bits in the SPIM & SPIS components?
Is there any specific reason why you would like to use 24-bit data?
By parsing 24-bit word into three 8-bit data, communication can usually be achieved.
The SPIM and SPIS components support data width from 8-16bits only.
