fpga - Altera DE2 interfacing with analog sensor



Can Altera GPIO pins read the analog output of a light sensor? The light sensor output is analog and I want the Altera to turn an LED on whenever the signal of the sensor is greater than some specific value.


Can I do that directly, or do I have to connect the output of the sensor to an ADC? How would I go about that?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
