Hi every one,
I try to drive a TCD1304AP linear ccd with PIC24Hj12gp201 Micro and share this driver with all of you,
This driver work about 60 Fps with minimum part and connection.
I connect TCD1304AP driectly to PIC and discard 74hc04 invert buffer driver that use in TCD1304AP PDF circuit. 2sa1015 transistor still remain.
try this and enjoy,
