Source files: -------------- dkactiontable.S Table of all supported action functions dkclock.c Clock configuration (Xmega oscillator) dkclock.h dkebi.c EBI configuration (external memory - 8MB SDRAM on Xplained board) dkebi.h dkfile.c File interface (used for stdio support and dkfopen() etc functions) dkfile.h dkfile_uart.c UART file interface (used by terminal emulation) dkfile_uart.h dkinteractive.c Interactive shell dkinteractive.h dkstring.c String manipulation functions dkstring.h dktables.h dktables.S Flash table manipulation dkterm.c Terminal emulation interface (uses dkfile.c file interface) dkterm.h dkvt100.c VT-100 terminal emulation dkvt100.h Makefile xplainer.c main() function actions/beep.c BEEP action - make a loud beep with the Xplained speaker actions/button0.c action executed when Button0 (SW0) pressed actions/button1.c action executed when Button1 (SW1) pressed actions/button2.c action executed when Button2 (SW2) pressed actions/button3.c action executed when Button3 (SW3) pressed actions/button4.c action executed when Button4 (SW4) pressed actions/button5.c action executed when Button5 (SW5) pressed actions/button6.c action executed when Button6 (SW6) pressed actions/button7.c action executed when Button7 (SW7) pressed actions/disco.c DISCO action actions/help.c HELP action actions/hotbutton.c HOTBUTTON action - set commands performed when buttons (SW0-SW7) pressed actions/hotkey.c HOTKEY action - set commands peformed when hotkeys (F1-F12) pressed actions/led.c LED action - turn on/off LED0-LED8 actions/peek.c PEEK action - read byte from a memory address actions/poke.c POKE action - write byte to a memory address Compiled files: ---------------- xplainer.eep Generated EEPROM contents for ATxmega128A1 xplainer.hex Generated FLASH contents for ATxmega128A1 In progress: ------------- actions/temp.c TEMP action - read temperature from NTC, using ADCB.0 Compiling: ----------- Type 'make' build Makefile. 'make clean' will remove object and linked binaries. 'make prog' will make clean, make, and use avrdude to program the target device. In the Makefile: ----------------- DEFS = -DF_CPU=32000000 -D_GLITCHER_VERSION_NUM=2 -DF_CPU=32000000 The 32MHz RC oscillator is selected by dk_clock_init() in xplainer.c. If oscillator settings are changed, this should be adjusted to match. -D_DK_VERSION_NUM=2 The version number for the compiled project. Adding an action: ------------------ 1) create actions/new.c with "char *dkaction_new( char *line )" function - return value isn't actually used, but unprocessed remnant of line should be returned 2) add action to dkactiontable in dkactiontable.S .string "new" .word dkaction_new 3) add actions/new.c to CSRC line of Makefile 4) add description and usage to actions/help.c "Hello, world!" example action: -------------------------------- 1) All action program code is in actions/hello.c 2) Add to dkactiontable: (dkactiontable.S): .string "hello" ; keyword "hello" - "Hello, world!" example .word dkaction_hello ; dkaction_hello() in actions/hello.c 3) Add actions/hello.c to CSRC = in Makefile 4) Add to printf_P() in dkaction_help() (actions/help.c): "HELLO (\"Hello, world!\" example action)\n" Hardware usage: ---------------- (as per Xmega-A1 Xplained board (blue PCB), 2011-05-22) EBI (SDRAM - 3-port EBI) PORTK.DIR = 0xFF; PORTJ.DIR = 0xFF; PORTH.DIR = 0xFF; LEDs (LED0-LED7) PORTE.DIR = 0xFF; buttons (SW0-SW7) PORTD 0-5 (inputs, pullup enabled) PORTR 0-2 (inputs, pullup enabled) thermsistor (NTC) PORTB 0 (ADC) PORTB 3 [NTC_EN] light sensor PORTB 1 (ADC) speaker PORTB 2 (DAC) PORTQ 3 [AUDIO_SD] dataflash (optional) SPIC PORTC 5-7 PORTQ 2 [DATAFLASH_CS] USB serial adapter (32UC3B1256) USARTC0 (PC2=RXD, PC3=TXD) 128-byte buffer for incoming data (96-byte limit before flow control kicks in) flow control disabled (not supported by 32uc3) 57600 8-n-1 comm to 32uc3 JTAG PORTB 4-7 J1 = PORTF (shared with board controller spi/board controller twi) J2 = PORTA <adc0-7> J3 = PORTD 0-5, PORTR 0-1 <gpio0-7> (shared with buttons) J4 = PORTC (PC2/PC3 USARTC shared with board controller) VPORT configs no vports needed/utilized interrupts: global interrupt enabled PMIC = LOLVLEX enabled interrupts: USARTC0_RXCINTLVL button presses Interactive interface: ----------------------- VT100 terminal emulation (cursor keys, insert/delete, function keys) Lines are terminated with carriage return (\r). On input, newlines (\n) are ignored. On output, newlines (\n) may be converted to carriage return (\r) - or expanded into CRLF (\r\n) sequence. NOTE: ctrl-Z works as pause! Terminal software: ------------------- Tested using minicom in Linux and PuTTY in Windows 7 using PJRC generic CDC ACM driver Settings: - 115200 8-N-1 - VT100 terminal emulation
