Help Needed: Implementing UART and SPI on Altera MAX II EPM240 CPLD

Hi everyone, I'm currently working with the Altera MAX II EPM240T100C5N CPLD and I'm trying to implement UART and SPI communication protocols on it. I'm using Verilog HDL and targeting a 3.3V logic ...

Hi,


For SPI master, you may check this design example https://www.intel.com/content/www/us/en/docs/programmable/683277/current/serial-peripheral-interface-master-in.html

This application note details the implementation of the SPI master in MAX II, MAX V and MAX 10 devices.

Design link: https://www.intel.com/content/www/us/en/design-example/715016/intel-max-10-fpga-an-485-serial-peripheral-interface-master-design-example.html


Will provide the UART part later.


Thanks,

Regards,

Sheng

@ShengN_Intel I have reviewed the links you provided, but I couldn't find any working sample Verilog code for SPI implementation on the MAX II EPM240 CPLD. As I am new to CPLD programming, could you kindly share any resources or sample source code for implementing SPI and UART on this device?

Thanks in advance.
