The download above is the complete assembler source code for Scriber v2.1, It may be viewed in Notepad or loaded into Microchip's Mplab X IDE, assembled and the hex file loaded into a PIC16F1615 chip using a PICkit3.
Version 2.1 of Scriber is identical to v1.0 with two exceptions :-
The TXD output on pin 7 is inverted so now both TXD and RXD (pins 7 & 8) are UART polarity (idle = 5v) for direct connection to a USB to TTL serial module.
The optional use analogue input on pin 12 has an input range of 0 to Vcc/2 for direct interface to a MAX9814 mic amplifier module. An internal 300 to 3KHz digital filter with HF pre-emphasis has also been added .
