some random notes about the parallax readers
* em4095 to pic16f627a (20pin ssop package) ** DEMOD_OUT (13) -> RB3/CCP1 (10) ** RDY/CLK (2) -> RB6/T1OSO/T1CKI/PGC (13) ** SHD (14) -> RA1/AN1 * pic16f627a to edge connector ** RB0/INT (7) -> OE# ** RB2/TX/CK (9) -> SOUT * pic16f627a to discretes ** RA7/OSC1/CLKIN (18) -> LED (1) ** RA6/OSC2/CLKOUT (17) -> LED (2) * em4095 xmit is controlled by MOD (12) ** this follows the same modulation scheme as DEMOD_OUT (13)
