Charlie’s Angels ALL PROJECT CODE Audio Control /////////////////////////////////////////////////////////////////////////////// // // 6.111 Introductory Digital Systems Laboratory, Spring 2006 // Team 14 "Charlie's Angels" // Final Project: Piano Dance Revolution // // Audio Control Modules (Lucia Tian) // /////////////////////////////////////////////////////////////////////////////// // Below is the Labkit Code from Nathan Ickes, modified to suit our purpose. // The instantiations and wirings follow. /////////////////////////////////////////////////////////////////////////////// // // Switch Debounce Module // /////////////////////////////////////////////////////////////////////////////// module debounce (reset, clock, noisy, clean); input reset, clock, noisy; output clean; reg [18:0] count; reg new, clean; always @(posedge clock) if (reset) begin count <= 0; new <= noisy; clean <= noisy; end else if (noisy != new) begin new <= noisy; count <= 0; end else if (count == 270000) clean <= new; else count <= count+1; endmodule/////////////////////////////////////////////////////////////////////////////// // // 6.111 FPGA Labkit -- Template Toplevel Module // // For Labkit Revision 004 // // // Created: October 31, 2004, from revision 003 file // Author: Nathan Ickes // /////////////////////////////////////////////////////////////////////////////// // // CHANGES FOR BOARD REVISION 004 // // 1) Added signals for logic analyzer pods 2-4. // 2) Expanded "tv_in_ycrcb" to 20 bits. // 3) Renamed "tv_out_data" to "tv_out_i2c_data" and "tv_out_sclk" to // "tv_out_i2c_clock". // 4) Reversed disp_data_in and disp_data_out signals, so that "out" is an // output of the FPGA, and "in" is an input. // // CHANGES FOR BOARD REVISION 003 // // 1) Combined flash chip enables into a single signal, flash_ce_b. // // CHANGES FOR BOARD REVISION 002 // // 1) Added SRAM clock feedback path input and output // 2) Renamed "mousedata" to "mouse_data" // 3) Renamed some ZBT memory signals. Parity bits are now incorporated into // the data bus, and the byte write enables have been combined into the // 4-bit ram#_bwe_b bus. // 4) Removed the "systemace_clock" net, since the SystemACE clock is now // hardwired on the PCB to the oscillator. // /////////////////////////////////////////////////////////////////////////////// // // Complete change history (including bug fixes) // // 2005-Sep-09: Added missing default assignments to "ac97_sdata_out", // "disp_data_out", "analyzer[2-3]_clock" and // "analyzer[2-3]_data". // // 2005-Jan-23: Reduced flash address bus to 24 bits, to match 128Mb devices // actually populated on the boards. (The boards support up to // 256Mb devices, with 25 address lines.) // // 2004-Oct-31: Adapted to new revision 004 board. // // 2004-May-01: Changed "disp_data_in" to be an output, and gave it a default // value. (Previous versions of this file declared this port to // be an input.) // // 2004-Apr-29: Reduced SRAM address busses to 19 bits, to match 18Mb devices // actually populated on the boards. (The boards support up to// 72Mb devices, with 21 address lines.) // // 2004-Apr-29: Change history started // /////////////////////////////////////////////////////////////////////////////// module labkit (beep, audio_reset_b, ac97_sdata_out, ac97_sdata_in, ac97_synch, ac97_bit_clock, vga_out_red, vga_out_green, vga_out_blue, vga_out_sync_b, vga_out_blank_b, vga_out_pixel_clock, vga_out_hsync, vga_out_vsync, tv_out_ycrcb, tv_out_reset_b, tv_out_clock, tv_out_i2c_clock, tv_out_i2c_data, tv_out_pal_ntsc, tv_out_hsync_b, tv_out_vsync_b, tv_out_blank_b, tv_out_subcar_reset, tv_in_ycrcb, tv_in_data_valid, tv_in_line_clock1, tv_in_line_clock2, tv_in_aef, tv_in_hff, tv_in_aff, tv_in_i2c_clock, tv_in_i2c_data, tv_in_fifo_read, tv_in_fifo_clock, tv_in_iso, tv_in_reset_b, tv_in_clock, ram0_data, ram0_address, ram0_adv_ld, ram0_clk, ram0_cen_b, ram0_ce_b, ram0_oe_b, ram0_we_b, ram0_bwe_b, ram1_data, ram1_address, ram1_adv_ld, ram1_clk, ram1_cen_b, ram1_ce_b, ram1_oe_b, ram1_we_b, ram1_bwe_b, clock_feedback_out, clock_feedback_in, flash_data, flash_address, flash_ce_b, flash_oe_b, flash_we_b, flash_reset_b, flash_sts, flash_byte_b, rs232_txd, rs232_rxd, rs232_rts, rs232_cts, mouse_clock, mouse_data, keyboard_clock, keyboard_data, clock_27mhz, clock1, clock2, disp_blank, disp_data_out, disp_clock, disp_rs, disp_ce_b, disp_reset_b, disp_data_in, button0, button1, button2, button3, button_enter, button_right, button_left, button_down, button_up, switch, led, user1, user2, user3, user4, daughtercard, systemace_data, systemace_address, systemace_ce_b, systemace_we_b, systemace_oe_b, systemace_irq, systemace_mpbrdy,analyzer1_data, analyzer1_clock, analyzer2_data, analyzer2_clock, analyzer3_data, analyzer3_clock, analyzer4_data, analyzer4_clock); output beep, audio_reset_b, ac97_synch, ac97_sdata_out; input ac97_bit_clock, ac97_sdata_in; output [7:0] vga_out_red, vga_out_green, vga_out_blue; output vga_out_sync_b, vga_out_blank_b, vga_out_pixel_clock, vga_out_hsync, vga_out_vsync; output [9:0] tv_out_ycrcb; output tv_out_reset_b, tv_out_clock, tv_out_i2c_clock, tv_out_i2c_data, tv_out_pal_ntsc, tv_out_hsync_b, tv_out_vsync_b, tv_out_blank_b, tv_out_subcar_reset; input [19:0] tv_in_ycrcb; input tv_in_data_valid, tv_in_line_clock1, tv_in_line_clock2, tv_in_aef, tv_in_hff, tv_in_aff; output tv_in_i2c_clock, tv_in_fifo_read, tv_in_fifo_clock, tv_in_iso, tv_in_reset_b, tv_in_clock; inout tv_in_i2c_data; inout [35:0] ram0_data; output [18:0] ram0_address; output ram0_adv_ld, ram0_clk, ram0_cen_b, ram0_ce_b, ram0_oe_b, ram0_we_b; output [3:0] ram0_bwe_b; inout [35:0] ram1_data; output [18:0] ram1_address; output ram1_adv_ld, ram1_clk, ram1_cen_b, ram1_ce_b, ram1_oe_b, ram1_we_b; output [3:0] ram1_bwe_b; input clock_feedback_in; output clock_feedback_out; inout [15:0]
