' Buffered outputs management: it drives two relays through the serial console, ' in RS 232, that selects the enabled and disabled status. ' The relays are driven by two I/O lines of microcontroller, connected to CN4 ' connector of GMM TST3, as described in electric diagram. ' The program describes its functionalities and uses a serial console provided ' of monitor and keyboard with a fixed physical protocol at 19200 Baud, 8 Bit x ' chr, 1 Stop bit, No parity. ' This console can be another system capable to support a serial RS 232 ' communication. In order to simplify the use it can be used a PC provided of ' one COMx line, that execute a terminal emulation program as HYPERTERMINAL or ' the homonym modality provided by BASCOM AVR (see IDE Configuration). ' The program works only when the GMM AM08 is mounted on Z2 socket of GMM TST3!! ' ' Added instructions: None. ' ' 29.07.12: uk_BASAVR_067.BAS - Ver 1.1 - By G.A. ' First version. ' ' '**************************** IDE Configurations ******************************* ' NOTE: in order to coorectly use this demo program, please execute the following ' steps: ' 1) Check the availability of M8DEF.DAT file into the directory where the ' BASCOM AVR is installed, copy it if not present and then restart the IDE. ' 2) Into the window "Options | Compiler | Chip" set: ' Chip: m8def.dat ' XRAM: None ' HW Stack: 64 ' Soft Stack: 32 ' Framesize: 64 ' XRAM waitstate: disabled ' External Access Enable: disabled ' 3) Into the window "Options | Communication" set: ' COM port = the PC line connected to GMM AM08, through GMM TST3 ' Baudrate = 19200 ' Parity = None ' Databits = 8 ' Stopbit = 1 ' Handshake = None ' Emulation = TTY ' Font = Terminal, Normal, 12 points, white colour ' Backcolor = Navy ' 4) At the end of compilation, after the code is programmed on GMM AM08, open ' the terminal emulation window of BASCOM AVR with the option: Tools | ' Terminal emulator (Ctrl+T) and then reset or powen on the Mini Module.
