This project is intented for people who are new to VHDL. Code for this design can be found on armadeus sourceforge GIT into firmware/leds/button_led/.
We will connect a switch and a led to the FPGA and use some VHDL code to toggle the led state each time the switch is pressed.
Some usefull informations:
The main FPGA page [1] of the armadeus wiki.
This document [2] gives a lot of usefull information on how to use ISE Webpack.
Page 9 of this document shows the devlight pinout matrix: [3]
Pages 28 and 29 of the APF datasheet shows the mapping of the devlight pinouts with the FPGA pinouts :[4]
Schematic
Anatomy of the circuit
The led_top.vhd is a VHDL file where the components of the circuit are instantiated and connected between them.
The functional diagram of the circuit is :
