PIC_PWM.zip
A timer1 version of a PWM encoder. All flags are set for the PIC18 family. With a 20MHz crystal we should be able to achieve at least 450KHz @ 8bits.

Interface_PIC4.c.zip
... for the USB-6008/9 DAQ of NI to use a fast incremental encoder since the 6008/9 only reaches 20KHz and the fast encoder can ... 50KHZ on a motor running at 200rmp s. The interface converts the encoder tick into a value from 1024 to 0 and sends it digitally. ...

hdbn_latest.tar.gz
This “core” is actually two cores – an HDB3/HDB2/B3ZS Encoder that converts NRZ
data into P and N pulses according to ITU-T G.703, and a HDB3/HDB2/B3ZS Decoder
that converts P and N pulses into NRZ data according to ITU-T G.703.
