/****************************************************************************** * README.TXT for count_binary software example. * * Project Contents * **************** * README.TXT This file. * count_binary.c The main C code. * count_binary.h C Header file containing various includes and LCD * convenience definitions. ****************************************************************************** * Description * ************* * A simple program which, using an 8 bit variable, counts from 0 to ff, * repeatedly. Output of this variable is displayed on the LEDs, the Seven * Segment Display, and the LCD. The four "buttons" (SW0-SW3) are used * to control output to these devices in the following manner: * Button1 (SW0) => LED is "counting" * Button2 (SW1) => Seven Segment is "counting" * Button3 (SW2) => LCD is "counting" * Button4 (SW3) => All of the peripherals are "counting". * * Upon completion of "counting", there is a short waiting period during * which button/switch presses will be identified on STDOUT. * NOTE: These buttons have not been de-bounced, so one button press may * cause multiple notifications to STDOUT. ****************************************************************************** * Requirements * ************** * This program requires the following devices to be configured: * an LED PIO named 'led_pio', * a Seven Segment Display PIO named 'seven_seg_pio', * an LCD Display named 'lcd_display', * a Button PIO named 'button_pio', * a UART (JTAG or standard serial) ****************************************************************************** * * Peripherals Exercised by SW * ***************************** * LEDs * Seven Segment Display * LCD * Buttons (SW0-SW3) * UART (JTAG or serial) ****************************************************************************** ** NOTE: For additional information, please see the top of count_binary.c. ** ** Behavior will be different on the 1C12 board, due to its of ** ** peripherals. ** ****************************************************************************** */
