We have built the evaluation board as per design document from "Programmable Logic Controller (PLC) I/O Module Front- End Controller with Tiva C Series ARM® Cortex™-M4 MCU"-- TIDA-00123. The document ID is TIDU191 - January 2014。
However, we can not find the CPLD source code for the SPI insterface. The CPLD chip is LatticeLC4064V-75TN44I.
Can you please privde the CPLD source code?
Many thanks!
