Some basic questions regards Altera Max V

[Altera_Forum]

hi, I have a project which using Altera Max V for reading data from a sensor and transmit it to a PC. I'm totally new to FPGA/CPLD as well as Altera Max V and I have some basic questions as following: 

- How to read/write data numbers from/to I/O pins ? since most of tutorial I have seen, they only work with logic value (0 or 1).  - In the datasheet of Altera Max V https://www.altera.com/en_us/pdfs/literature/hb/max-v/max5_handbook.pdf , it says global clock frequency fcnt = 152MHz (e.g), is this   value also the operating frequency of the device?  - And if I want to use a trigger, do I need an external timer/trigger ?  Thanks very much Le

Try to redo some simple sample projects, and implement them on FPGA. 

Reading from Input & writing to outputs is simple in Verilog/VHDL. Depending on your sensor interface you may need simple or complex interface. The frequency of device will be determined after you implemented your design. It may be 100 MHz or 250 MHz, etc. TimeQuest reports how fast your design can run.
