+Memory Summary: (V 1.8)

+    Program space        used   C6Fh (  3183) of  1000h words   ( 77.7%)

+    Data space           used    9Bh (   155) of   100h bytes   ( 60.5%)

+    EEPROM space         used     0h (     0) of   100h bytes   (  0.0%)

+    Data stack space     used     0h (     0) of    5Eh bytes   (  0.0%)

+    ID Location space    used     0h (     0) of     4h bytes   (  0.0%)

+

+

+Testaufbau: 

+

+Zwei Steckbretter,

+urspruengliche Version des Programms als Empfaenger, 

+aktuelle Version als Sender, Aufzeichnung mit putty,

+angeschlossen jeweils per USB2RS232-Kabel von Conrad

+(972543, basierend auf Prolific PL2303). Soft-UART 

+fuer Input, da 12F1820 keine Kontrolle ueber Input-

+Polaritaet erlaubt und ich fuer Testaufbauten eine

+Minimalbeschaltung bevorzuge.

+

+Kurze Distanz

+(~30 cm) zwischen Sender und Empfaenger), keine genaue Ausrichtung.

+Stromversorgung wahlwweise mit 5V via PICkit 2 oder 3x1.2V NiMH-AA.

+OFF mit VAOVA TV-2900HDD FB

+Simple minded software bit banging async RS232 implementation for Microchip XC8

+

+http://en.wikipedia.org/wiki/Bit_banging

+

+Tested with 2400, 9600 and 19200 baud on a 4 MHz 16F675 so far

+Tested with 9600 baud on a 32 MHz 12F1840. 

+19200 softuard doesn't work.

+Necessary definitions (examples)

+#define FCY 1000000             // cycles per second (4 MHz PIC)

+#define SOFTUART_RXPIN  GPIO5   // if input is desired

+#define SOFTUART_TXPIN  GPIO4   // if output is desired

+

+Optional definitions

+

+#define SOFTUART_BAUD 19200     // default: 9600

+#define SOFTUART_STDIO 1        // if definition for getch, putch is desired

+                                // default: 0

+#define SOFTUART_DI 1           // if interrupts are to be disabled during IO

+                                // default: 0

+#define SOFTUART_MARK 0         // 0: not inverted (default: 1)
